for me, needing administrator privileges is a no go. Also, suppose
that symlinks are implemented, should we also add lstat() and other
Unix functions that have a symlink as argument ?

[Mingw-w64-public] _access and predefined modes

2021-08-10 Thread Vincent Torri
Hello

according to MSDN (see
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/access-waccess?view=msvc-160)
the valid modes of _access are 0, é, 4 and 6.

But in io.h, we have :

#defineF_OK0/* Check for file existence */
#defineX_OK1/* Check for execute permission. */
#defineW_OK2/* Check for write permission */
#defineR_OK4/* Check for read permission */

is it normal ?

"Setting a higher resolution can improve the accuracy of time-out
intervals in wait functions. However, it can also reduce overall
system performance, because the thread scheduler switches tasks more
often. High resolutions can also prevent the CPU power management
system from entering power-saving modes. "

It's more a Windows question than mingw one

basically :

to load the DLL : LoadLibrary()
to get the function pointer of the function in your DLL : GetProcAddress()
to free resources : FreeLibrary()

example attached

I suggest that you download dependency walker [1] to see if your
functions in your  correctly exported

[Mingw-w64-public] missing C api for direct composition

2020-11-06 Thread Vincent Torri
hello

so trying to port in C the code in
https://docs.microsoft.com/en-us/archive/msdn-magazine/2014/june/windows-with-c-high-performance-window-layering-using-the-windows-composition-engine,
i've seen that there is no C API in dcomp.h (dcomp.h/idl does not
exist in wine)

I hope someone will be able to add it.

thank you

i'm not familiar at all with the mingw-w64 headers, indeed. I'm just
guessing stuff by comparing what is in d2d1.h,  d2d1_1.h and the
d2d1_1.h generated with widl.

Question:

I have added ID2D1Properties C API (see attached diff). In d2d1.h,
STDMETHOD_ was used for the functions in the Vtbl struct. Should I do
the same ?

i can add what is missing part by part in d2d1.h. What is the standard
procedure ? if there is a github mirror and if PR are a possible way
to provide patches, i can do that

i also have an error that i do not understand

when i use

ID2D1Factory1_CreateDevice(***);

the compiler says that

d2d.c:12:60: error: 'ID2D1FactoryVtbl' has no member named 'CreateDevice'
   12 | #define ID2D1Factory1_CreateDevice(this,A,B)
(this)->lpVtbl->CreateDevice(this,A,B)
  |^~
d2d.c:301:16: note: in expansion of macro 'ID2D1Factory1_CreateDevice'
  301 | if (FAILED(ID2D1Factory1_CreateDevice(factory,
dxgi_device, _device)))
  |^~

i don't understand why. I've properly defined

#define D2D_USE_C_DEFINITIONS
#define _WIN32_WINNT 0x0A00

before inclusion of d2d header

any idea why ?

for example, adding in d2d1_1.h around line 1054 :

i know how to use fgrep...

what is missing is the classic C API, like (in d2d1_1.h) :

ID2D1Factory1_QueryInterface

that is, a define that call the method from the "virtual table" :

#define ID2D1Factory1_QueryInterface(this,A,B)
(this)->lpVtbl->Base.Base.QueryInterface((IUnknown *)(this),A,B)

it calls QueryInterface from the IUnknownVtbl structure, through
Base.Base in the define above

These are those defines that are missing.

Same for BeginDraw and EndDraw

i know, i already do that and i already call direct3d, direct2d and dxgi C API

btw, without linking to the dxgidebug dll :

DXGI_DEBUG_ALL and IID_IDXGIDebug are defined only with C++ in dxgidebug.h

if i link against the dll directly, IDXGIDebug_ReportLiveObjects is undefined

so i guess that ass all the other symbols work, there is something in
the import lib that takes care of the C API

hello

i've updated mingw-w64 with pacman in MSYS2 and i have this warning
each time gcc is called :

C:/Documents/msys2/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe:
warning: --export-dynamic is not supported for PE+ targets, did you
mean --export-all-symbols?

gcc has been updated to 10.2.0

is it a bug in the msys2 package ?

that makes sense. Is it possible to tell gcc to use msvcr*.dll instead
of msvcrt.dll ?

i've checked in cmd too, same result

But there is anyway something strange to me :

myprog_gcc.exe and myprog_vs are *both* run in MSYS2, and the result
is different. So I don't think it's related to path translation. It
would suggest something related to how gcc builds the binary

the file is : Moș_Crăciun_cântece.txt
I print it in the prog with printf :

[Mingw-w64-public] runtime difference between code compiled with VS and gcc

2020-08-26 Thread Vincent Torri
hello

(sorry, the previous mail has wrong topic)

I have this simple code :
-
#include 

#include 

int main(int argc, char* argv[])
{
FILE* f;
if (argc < 2)
{
printf("%s\n", argv[0]);
return 1;
}

f = fopen(argv[1], "rb");
if (!f)
printf("bad\n");
else
printf("good\n");
return 0;
}
-

of course, both compile with VS and on MSYS2+mingw-w64

The problem is runtime. I don't know if it is important or not, but I
am running Windows 10, french edition.

So, I have a file which has a romanian symbol : Moș.txt

1) if I run in MSYS2 ./myprog_gcc (compiled with gcc) Moș.txt, "bad"
is displayed

2) if I run in MSYS2 ./myprog_vs (compiled with VSc) Moș.txt, "good"
is displayed

does someone have an idea why there is such difference ?

thank you

If you are familiar with unix, you can install MSYS2 (which simulates
a posix terminal) and use the pacman command to install gcc and
mingw-w64

in addition, i prefer cross compile cmake-based projects instead, even
in MSYS2. you must open the MinGW 64 bits shell to cross compile for
64 bits :

- cross.txt -

set(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_SYSTEM_PROCESSOR AMD64)
set(CMAKE_C_COMPILER x86_64-w64-mingw32-gcc)
set(CMAKE_CXX_COMPILER x86_64-w64-mingw32-g++)
set(CMAKE_RC_COMPILER x86_64-w64-mingw32-windres)

- end of cross.txt -

cmake -DCMAKE_TOOLCHAIN_FILE=cross.txt -G "Unix Makefiles"

Re: [Mingw-w64-public] errno not set by bad call to strtof()

2020-01-08 Thread Vincent Torri
try to load the symbol to bypass the mingw defines (LoadLibrary +
GetProcAddress and call the symbol)

also try without -std=c99 (and with -std=c89, as gcc sets itself by
default to gnu11 or something like that, iirc) to see if it works.
strtol always exists in Windows, whatever the standard is on Unix.

the look at the official doc :
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/strtof-strtof-l-wcstof-wcstof-l?view=vs-2019

as strtof is a function in msvcrt.dll, maybe it's a bug in the implementation.

[Mingw-w64-public] wrong declaration of InetNtopA and InetNtopW

2019-04-19 Thread Vincent Torri
hello

in ws2tcpip.h, i have the following declarations of these 2 functions :

WINSOCK_API_LINKAGE LPCWSTR WSAAPI InetNtopW(INT Family, PVOID pAddr,
LPWSTR pStringBuf, size_t StringBufSIze);
WINSOCK_API_LINKAGE LPCSTR WSAAPI InetNtopA(INT Family, PVOID pAddr,
LPSTR pStringBuf, size_t StringBufSize);

that is the 2nd parameter is a void *

But in the doc :

https://docs.microsoft.com/fr-fr/windows/desktop/api/ws2tcpip/nf-ws2tcpip-inet_ntop
https://docs.microsoft.com/fr-fr/windows/desktop/api/ws2tcpip/nf-ws2tcpip-inetntopw

the 2nd parameter is a  const void *

is it normal or is it a bug in the declaration ?

thank you

use the mingw-w64 toolchain (sould be available in your freebsd distribution)

i686-w64-mingw32-gcc, etc... for 32 bits

x86_64-w64-mingw32-gcc, etc... for 64 bits

those 2 files are in your gcc installation directory. They must be

these above should be part of Windows.

normally you only need to copy the 2 above gcc dll where your dll is located.

2017-05-28 Thread Vincent Torri
it seems that it is part of gcc, so maybe the mingw-w64 maintainers should
be able to answer you

you wanted a library which provide stack traces.

for libbacktrace, I can see in
https://github.com/gcc-mirror/gcc/tree/master/libbacktrace so PE/COFF
commits and file. So I guess it is possible

try

autoreconf -vif

and

./configure --host=i686-w64-mingw32
or
./configure --host=i686-w64-mingw32

for respectively 32bits and 64bits support

I have written a small library and app around memory checking and PE
files. It is called examine and can report backtraces (using libbfd
for stack trace). It is here :

https://vtorri.github.io/examine/
https://github.com/vtorri/examine

I use MSYS2 + mingw-w64 for compilation, or Visual Studio.

[Mingw-w64-public] GUID definition in guiddef.h

2017-04-28 Thread Vincent Torri
Hello

in guiddef.h, a GUID is a struct organized as : 4 bytes, 2 bytes 2
bytes and 8 times 1 byte

but according to
https://msdn.microsoft.com/en-us/library/dd354925.aspx at the bottom :

"The correct format of the GUID string is
{CDEF7890-ABCD-1234-ABCD-1234567890AB} where 0-9, A-F symbolizes
hexadecimal digits. "

that is, the GUID structure should be organized as : 4 bytes, 2 bytes
2 bytes 2 bytes and 6 times 1 byte

is it normal that the GUID structure does not follow the MSDN doc ?

indeed, your test works here too

after a fgrep in the entire repo, FLT_EPSILON is defined as
__FLT_EPSILON__ in lib/***, not include/, the latter being defined
somewhere

sorry for the noise

Re: [Mingw-w64-public] [PATCH v7] Add include/iscygtty.c

2016-11-12 Thread Vincent Torri
i still don't understand why not using GetConsoleMode() and see if it
fails or not.

if it fails : redirection is done with named pipes
if not : it's standard win32 I/O

it's simple and works in my tests (DOS console, MSYS1, mintty, MSYS2
and cygwin terminal >= 1.8)

Re: [Mingw-w64-public] [PATCH mingw-w64] Add include/iscygtty.c

2016-11-10 Thread Vincent Torri
two cases :

1) pipe redirection : mintty and therefore cygwin (>= 1.8) terminal
and MSYS2 terminal (as the 2 latters are based on mintty)
2) MSYS1 and CMD console

ConEmu is a specific case as, if i'm not mistaken, it can switch from
one redirection to the other one

PS: i've also replied to the mingw-w64 ML, Mihail, maybe you should
send again the files to the ML

advapi32.dll depends on kernel32.dll (you can see that with dependency
walker for example), and the order of the -l flags is important : from
right to left : the "less dependent" to the "more dependant". So pass
to the linker "-ladvapi32 -lkernel32" because advapi32.dll depends on
kernel32.dll

[Mingw-w64-public] does linker correctly set the creation date of a PE file ?

2016-02-07 Thread Vincent Torri
Hello

with my little Examine tool, or with the 'sigcheck' tool from
sysinternal, it seems that the TimeDateStamp field of the
IMAGE_FILE_HEADER structure, which is "the date and time the image was
created by the linker" (see
https://msdn.microsoft.com/en-us/library/windows/desktop/ms680313%28v=vs.85%29.aspx
) is not correctly set. It returns 01/01/1970 as date (the local time
vary from file to file)

Can someone confirm that ? If yes, is it possible to fix this ?

thank you

2016-02-07 Thread Vincent Torri
It's not a problem of striping files or not (the debug section is not
involved here). But anyway, i've just did this :

gcc -g -O2 -o pi pi.c

then, I run the sigcheck tool. Here is the output :

$ /sigcheck.exe ./pi.exe

When I parse myself the TimeDateStamp field in the IMAGE_FILE_HEADER

ft.dwLowDateTime = uli.LowPart;

my point is that the timestamp is incorrect (it is set to 0, which is wrong)

Hey

it's indeed RtlInitializeCriticalSection() which is called. You should

No luck. I have removed all the hooks except HeapAlloc. If I test
Examine with a program with only 1 malloc(), malloc is not detected.

I've already patched HeapAlloc(), but malloc is already patched. I'll

[Mingw-w64-public] patching IAT and _strdup() and malloc() functions

2015-12-14 Thread Vincent Torri
Hello

I am still working on Examine, my small valgrind-like memory leak
detector (http://vtorri.github.io/examine/) and I have 2 questions.

First, I recall that it works by doing DLL injection with
CreateRemoteThread, and API hooking by patching the IAT.

So Examine is working well, now, but I have 2 questions, about
_strdup() and malloc() :

1) If I call malloc() in a program, it is detected by Examine. If I
call _strdup(), malloc is not detected at all, while MSDN says that
_strdup() "calls malloc to allocate storage space" (see
https://msdn.microsoft.com/en-us/library/y471khhc.aspx). Does someone
have an idea why malloc() is  not catched ?

2) So to fix 1), i've just patched the IAT to detect _strdup() (but
i'm not satisfied with this). Now if I call strdup(), _strdup() is not
detected. I thought first that strdup() was a macro, but it is
actually declared in string.h. Does someone know why strdup() is not
catched too ?

thank you

[Mingw-w64-public] WS_EX_NOREDIRECTIONBITMAP is not available

2015-06-14 Thread Vincent Torri
Hello

I wanted to use WS_EX_NOREDIRECTIONBITMAP on my Win 7. According to
MSDN, there is no Windows version information for that flag. Maybe it
has been introduced in Windows 8.0 or 8.1

[Mingw-w64-public] Fwd: Examine - a small Windows memory leak detector and PE file viewer

2015-06-06 Thread Vincent Torri
Hello

i have been working on a small application named 'Examine'. Its
features are basically 3 tools:

1) 'memcheck' (same name than valgrind's tool): a memory leak detector
with some memory checks for Windows,

2) 'depends': a PE file dependency viewer (CLI and GUI) ala dependency walker,

3) 'view': a PE file viewer to view the data values of the PE file.

Both 'depends' and 'view' tools can be run on Windows and Linux (and
any UNIX I think as Idon't use anything Linux-specific) but the
'memcheck' tool can only run on Windows.

The source code is hosted on github: https://github.com/vtorri/examine

It is a Work In Progress (tm) so it's not complete and certainly have
some bugs that I am not aware of.

If you want to give it a try, follow the instructions below.


INSTALLATION

1) Windows:

I've tested only with MSYS + win-builds

If gcc is installed in /opt/windows_64:

CFLAGS=-g -O0 ./configure --with-libbfd-prefix=/opt/windows_64

(./autogen.sh instead of ./configure, the first time)

then make  make install

2) Linux:

./configure
make  make install


USAGE

1) 'memcheck' tool

Of course it can not be run on Linux (use valgrind on linux...). The
usage is like valgrind:

examine the_app.exe the_app_arguments

the_app.exe should be compiled with -g -O0 to have a useful backtrace.
I use libbfd to get the backtrace (-On with n 0 adds
-fomit-frame-pointer)

The output mimics the valgrind output.

Currently supported functions: malloc, calloc, realloc, free,
HeapAlloc and HeapFree. More will be added soon

I have provided a test example, named examine_test :

examine /usr/local/examine_test

With that test, the output is the following (mimic also the valgrind
ouptput) : http://codepad.org/uRR1HnYm

2) 'depends' tool

It tries to mimic Dependency Walker

you have 3 possible outputs:

a) text output, with the dependecy tree:

examine -q --tool=depends pe_file

It should work on Windows and linux

b) text output, with the dependency list (like ldd):

examine -q --tool=depends --list pe_file

It should work on Windows and linux

c) GUI output, with a GUI which mimics Dependency Walker

examine -q --tool=depends --gui pe_file

The GUI is not perfect and should actually not be tried right now (it
can be very very slow)

2) 'view' tool

It views the content of  a PE file

examine -q --tool=view pe_file

It should work on Windows and Linux. There is also a GUI but not
really finished yet



Feel free to give remarks, ideas, etc...

thank you

Vincent Torri

 Hi,

 I've just pushed a redirect from http://mingw-w64.sourceforge.net to
 http://mingw-w64.yaxm.org in order to serve a new website.

 I have been taking care of the website for at least a couple years now.
 Not that I particularly enjoy doing PHP, CSS and Javascript but there
 was a need. However I suck at design and I had very little time
 available, which meant all the changes I could do were minimal.

 Last week I finally bit the bullet and spent half a day assessing
 whether something based on dokuwiki could work and then spent a day
 moving the data from the website to that dokuwiki and tweak its them and
 plugins.
 This was discussed a bit over IRC and the switch has been hurried by the
 release of 4.0: I was feeling miserable each time I had to update
 anything on the website and I really didn't feel like taking one hour
 just to add a section to the existing layout, especially knowing the
 website replacement was going to occur soon.

 The now-old website is still available, only masked through a redirect.
 Please speak up if you are not pleased with the new one.

 One notable change is that the website is not served through
 sourceforge.net anymore. I had started with everything on SF but more
 often than not, the pages would fail to load. Unfortunately this means
 there is a user-visible redirection on a temporary subdomain; this is
 expected to remain for one month at most.

 NB: this does not change anything else; nothing but the website that has
 been visible on http://mingw-w64.sourceforge.net changes.

 The wiki from sourceforge is going to be abandoned. Well. Noone has
 touched wiki2 since it was set up a year ago so it's not a big loss.
 Dokuwiki should be a nicer place for wiki changes (faster, cuter, and
 fully integrated into the website obviously).
 The only minor downside currently is that users cannot register
 themselves to change the website. This is minor since I can do it on
 request and because the set of pages that is currently up will not be
 editable by most people anyway (i.e. main page, downloads). This will
 be fixed.

 On a final note I'd like to thank the author of the initial mingw-w64
 website. As far as I remember he had a company named CodeCamel but
 currently the website is MIA but the domain name has been parked with
 seemingly-innocuous link spam. That website has served mingw-w64 well
 for around 5 years.
 Its replacement did not happen out of discontent but because a lot has
 happened over these 5 years, both the web (mobile, many new viewport
 sizes, saner browsers, ...) and for mingw-w64 (so many more users,
 contributors, activity on all fronts and much more content).
 Working with sourceforge.net SSH access was the painful part as it was
 slow and not having a CSS theme used (and tested) by many other websites
 made the process brittle and time-consuming.

 I wished there had been time to bring the topic on the mailing-list
 before doing the switch but v4.0 timing made that hard and I've also
 taken great care to not lose anything in the process. Any constructive
 criticism is welcome; don't hesitate.

[Mingw-w64-public] Help required about process and dll injection

2014-11-14 Thread Vincent Torri
Hello

My question is not related to mingw-w64 itself, I know, but i'm
desperatly trying to find help. Kai told me that maybe some people
here could help me.

I'm trying to write some kind of debugger to find leaks in a program
by injecting a DLL in the process I want to debug [1]. I have already
a code that injects a dll in a child process (but not in its
dependencies, and that is the problem). I use the CreateRemoteThread
method. So I do basically :

1) CreateProcess of the process I want to debug, in suspend mode
2) I inject the DLL.

but it is not good because :

a) the state of the process is not in a good shape when it is in suspend mode
b) and at this stage, the dll of the dependencies are not even loaded.
And I need them

so I've read here and there that a (and certainly the correct)
solution is to patch the entry point of the process with an infinite
loop. A rough description is here :
https://opcode0x90.wordpress.com/2011/01/15/injecting-dll-into-process-on-load/

but :

i) there is no detailed code (there are some non-detailed functions
and i'm not good enough to write them :-( )
ii) even if it works it's only for x86 (32 bits) and not x86_64 (the
CONTEXT structure has no Eip member on x86_64. Maybe using the Rip
member ?)

So does someone know where I can find detailed description for i) and
ii) (a piece of code would be the best :-p) ?

thank you

 Possible solution:
 0) Load the debugee in suspended mode;
 1) Calculate the address of its entry point (typically mainCRTStartup or 
 WinMainCRTStartup) from its PE header, since its header should now have been

I guess that I call CreateFilemapping() like that :

CreateFilemapping(pi.hProcess, NULL, PAGE_READWRITE, 0, 0, NULL);

with pi the PROCESS_INFORMATION structure passed to CreateProcess() ?

 2) Overwrite the byte at that address with 0xCC (a.k.a. int3 instruction on 
 both x86 and x64);
 3) Resume the process and it should hit the breakpoint, after all 
 statically-linked DLLs have been loaded successfully, before any static 
 constructors are invoked;

shouldn't I have to wait a bit so that all the DLL are loaded ? It
might take some time to load them, no ? That's what is done in the
link that i have posted

 4) Restore that byte;
 5) Inject your DLL;
 6) Resume the process as normal.

 I haven't tested it, but it should work. Some debuggers (specifically, 
 OllyDbg) have an option to decide where the first breakpoint should be set, 
 at system breakpoint(before any DLLs are loaded), PE entry(the point 
 mentioned above), or WinMain.

 Hmm have a test yourself. :
 Since you are writing a debugger you can wait for the breakpoint. The system 
 generates an exception with code EXCEPTION_BREAKPOINT and your debugger 
 should handle it. Otherwise your program would be terminated.

i'm currently writing something more like valgrind, actually. Not a
program like gdb. So i'm not sure i can call what i write a debugger

[Mingw-w64-public] about localtime_r()

2014-09-27 Thread Vincent Torri
hey

in the mingw-w64 version i have (installed by win-builds 1.4),
localtime_r() is guarded by _POSIX (see time.h), so any program that
uses localtime_r has to pass -D_POSIX.

jony mentioned on IRC that, as guards were removed for strtok_r(),
maybe it should also be the case for localtime_r.

also note that http://linux.die.net/man/3/localtime_r gives another
set of guards.

what do you think ?

 to speed up work on that a bit and would like to do a 5 day hackathon
 to port VLC to WP ARM, and Xbox 1 targets.  And of course this needs
 also some work on mingw-w64.  The ARM support in mingw-w64 is already
 about 50% completed.  A rough binutils/gcc compiler support is already
 existing, nevertheless we still need to do all target-libraries for
 PE-ARM in gcc.  Later is depending on complete crt-support for ARM
 architecture.

 So if you feel like being helpful and interested in joining such event
 please contact JB or me, or reply to this thread.

 This event is still in planning phase. We thought about let this event
 happen at end of September (tentative 24th up to 28th). And it is
 intended to run in .de.

i was the one who ported the EFL (set of graphic libs) to Windows CE
