Is it possible/reasonable to check the settings by default? Maybe more
people will be affected by the Win10 issue and not by disabling load
symbols by default?


If we could get a more uptodate gdb for 64 bit that should solve it
(providing it passes the gdbmi test case without crash)

If the option is active and you develop a library project, then you can
not debug it.

-
In the past 64 bit did not work because of SEH, so the error was
encountered with 32 bit. For 32 bit gdb was updated to 7.7.1 and that
should (afaik) fix the issue. (On 32 bit gdb > 7.7.1, tested up do gdb
10 are less stable, they crash in the testcase)


What about fpdebug? Does it work for Win64?

Better read Jonas' comments on that commit first:


The code that was committed for UTF8Delete(utf8string) in 
http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/components/lazutils/lazutf8.pas?root=lazarus=50850=50849=50850
 makes no sense:
* it's the "string" version that needs this wrapper, not the utf8string one (it's 
probably done because the "string" version is more commonly called, but that doesn't help 
if the current approach is wrong)
* changing the codepage of tmp at the start is a no-op, since it's an empty 
string at that point and you can't change the code page of an empty string 
(it's a nil pointer)
* if you can reasonably expect any custom string type to already have an utf8 code page, 
it's utf8string. It's not guaranteed of course, but it's much more likely than for a 
random "string"-typed variable (even if defaultsystemcodepage = CP_UTF8, 
because system unit routines may return rawbytestrings that have different code page) -- 
so if you want to change the code page of strings to make sure it's utf8, that should be 
done in the plain string version rather than in the utf8string version.

I also made an error in my original code (apart from the missing rawbytestring typecasts when 
calling SetStringCodePage). The "s:=tmp;" at the end needs to be 
"s:=RawByteString(tmp);" to avoid a codepage conversion in that assignment.

Re: [Lazarus] [offtopic] Debugger is not working...

1) Antivirus. I ve seen it before, the AV removes the exe before it
can run. (some av do that without asking, even if they are set to
ask first). The list of AV is always changing, as they get updated
and may stop doing so.

I don't use antivirus, if you don't count WDefender as antivirus. As on W10 we 
can't let it disabled, so, now I use an antivirus.
Anyway, he isn't removing any file.


2) Can you find and run the exe outside the IDE?

Yes, I'm using a lot of ShowMessage to debug...



3) which lazarus? 1.4 (32bit ?).x or 1.6 (32 or 64 bit?)

For 1.4 (32 bit) try download the alternative gdb 7.7.1 from our
sourceforge site. 1.6 already has that.


It's heappening since 1.4.2. I always use 32bit. On Laz 1.6RC1 the problem 
still lives...


4) name of directory in which you saved the project, and where the
exe is. For testing use a folder without spaces or accents (in
the entire path, so no "documents and settings". Use C:\mytest

Well, I'm thinking about special chars on path now. Old projects that has 
special chars on path worked fine on past but now they don't work. Spaces never 
was a problem, maybe now? Another thing to think about is that my projects are 
store on Onedrive's and Google Drive's folder.

Does it work outside the IDE? (without gdb).

If 64 bit: We currently have no maintainer for 64 bit gdb, so the gdb 
exe for 64 bit is rather old. It may not work well on modern windows.

My issue is not really the --pcp option to separate the lazarus
configs. I have done so already for the older lazarus.

Instead it is about actually being able to build the RC1 lazarus on
the Pi2 using the fpc. I have now tried both the 3.0.0 version and the
older 2.6.4 with the same results. So somehow it seems like there is
something amiss in the lazarus sources, which depend on the platform
it is being compiled for, or else the fpc 3.0.0 installation is
incomplete in some way. Is the process unit part of lazarus code or
fpc code?

Building Lazarus worked fine in the Linux Mint 17.2 virtual machine
but won't work here. Same sources checked out from svn in both cases,
yet there is this error about the missing process unit...
>Fatal: (10022) Can't find unit process used by RegisterFCL

Does RegisterFCL work differently on Linux x64 than on Linux ARM?

By the way I found a process.pp file in the fpc 3.0.0 sources:
packages/fcl-process/src/process.pp

Maybe the lazarus "make bigide" does not search the correct directory
so it misses this on an ARM platform? Just guessing now of course...

There is no const modifier in this excerpt.

Re: [Lazarus] Debian Packager released

[Alexsander Rosa]

I've tested it, congratulations, it works fine.
However I have a suggestion: an option to select the destination.
It seems it always installs at /usr/local/bin.
I would like to install into /opt/company-name/app-name to add other files.
What do you think?

Hi,

always get that message ('Hit stop and hope the best, we're pulling

I thought updating lazarus should help but I got no success.

It heappens with all projects.

Is there a way check what is heappening?


1) Antivirus. I ve seen it before, the AV removes the exe before it can 
run. (some av do that without asking, even if they are set to ask 
first). The list of AV is always changing, as they get updated and may 
stop doing so.


2) Can you find and run the exe outside the IDE?

3) which lazarus? 1.4 (32bit ?).x or 1.6 (32 or 64 bit?)
For 1.4 (32 bit) try download the alternative gdb 7.7.1 from our 
sourceforge site. 1.6 already has that.


4) name of directory in which you saved the project, and where the exe 
is. For testing use a folder without spaces or accents (in the 
entire path, so no "documents and settings". Use C:\mytest

Yes.

I don't know, TBH.

Re: [Lazarus] how to Draw Data Matrix by TLazBarcode

Thank you for your answer. I solve this problem. I'm so so so appreciate.

But I have one more problem. How to change Data Matrix width and Height.

if you know any way, please share me.



Hello,

Can you be more precise ? Which kind of width & height ? With StrictSize 
checked the widget size would be 1x, 2x, 3x,...,Nx to fill as much as 
possible of the print space keeping pixels exactly as expected by the 
format so no "half pixel" dots appears. Non StrictSize can be used if 
the generated image would be big enought that non expected pixels 
(lines, "half pixel") will not affect the read capability (usually 
bigger than 4x original size).

Maybe an anti-virus and file locking issue?
With windows 8.1 I can't run and debug my apps within Lazarus if AVAST's 
services are running.
