[Mono-dev] Generic Variance
This is a patch to add runtime support for generic variance. This patch
lacks certain features of the spec. For example, only reference type
variance is supported. Also, the runtime does not enforce the validity of
variant parameters (that they only appear in interface and delegate types,
that covariant parameters only appear as return types and in interface
inheritance, and the contravariant parameters only appear as by-value method
parameter types). This means it is possible to violate type safety will
invalid CIL. The patch is contributed under the MIT/X11 license. It is
attached and inline.

This is a yes, me too response, but I've done some analysis on my own.
First I was stuck on the DllNotFoundException. My next step was to call
GDALAllRegister on gdal_fw (Gdal_wrap uses this one).
(*All code was not cut and pasted*)
[DllImport(gdal_fw)]
public static extern void GDALAllRegister();
And created a small console app that runs this. When run from command line
it runs just fine, but when run with mono it gave a DllNotFoundException
(startled). The DLL could be found just fine, the environment path was the
same, it pointed to the bin of gdal (I've used fwtools 2.2.8) ,.. so what
could have gone wrong?
I've PInvoked LoadLibrary from Kernel32
[DllImport(Kernel32), SetLastError = true)]
Public extern static int LoadLibrary(string name);
When you run :
Console.WriteLine(LoadLibrary(gdal_fw));
With normal .net it runs fine, a handle is returned. under mono it fails
with error code (getlasterror) 182 meaning invalid ordinal?
I've checked the dll dependencies of gdal_fw,.. and long story short, it
seems the ssleay32.dll fails to load (182) when mono is run. The
dependencies of ssleay32 load just fine. btw folks these are all unmanaged
dll's..
Now it's time for me to give up. Hoping someone finds a solution, or an
explanation why this would occur with mono running.
regards
Floris Briolas
(used mono 2.0.1 on win xp)
Sorry but i don't speek english...
i was found the solution to the ssleay32.dll load problem.
command line del c:\your mono path\bin\libeay32.dll
and if you run this code snippet:
[DllImport(Kernel32, SetLastError = true)]
public extern static int LoadLibrary(string name);
static void Main()
{
...
Console.WriteLine(libeay32.dll: +
LoadLibrary(libeay32.dll).ToString
());
Console.WriteLine(ssleay32.dll: +
LoadLibrary(ssleay32.dll).ToString
());
...
}
command line mono test.exe
libeay32.dll: 21037056
ssleay32.dll: 22347776
and it seems that works well!
it seems a bug.
regards

You mentioned you don't want to use SWIG, so its probably foolish of me to comment, but after avoiding swig for years, I've recently had a lot of success in both Windows and Linux.

[Mono-dev] Patches to enable off-tree build

It should be nice to allow off-tree builds. And the attached

[Mono-dev] high precision real cpu time in MONO (on linux)
Hello All, I am a newbie to Mono and to C# ; I am using only Debian/Sid/AMD64 on a recent linux 2.6.29-rc3 kernel (with CONFIG_HIGH_RES_TIMERS CONFIG_HZ=1000) , mono 2.2 I am searching for a way to measure real clock and cpu time with high precision. The linux system call is clock_gettime. Apparently mono has some way to get it, since mono-2.2 contains the file mono/utils/mono-time.[ch] with functions gint64 mono_100ns_ticks(void) MONO_INTERNAL; gint64 mono_100ns_datetime (void) MONO_INTERNAL; I blindly guess that MONO_INTERNAL would mean that these functions are not accessible from C# 3.0 code. What is the easiest way to get high precision (at least high resolution) time on Linux? Ideally I would like to get CLOCK_REALTIME or CLOCK_MONOTONIC and CLOCK_THREAD_CPUTIME_ID. But any way of measuring milliseconds real cpu (preferably thread) time is ok. Any clues?

So I was wondering if anyone can point me to a document/page that explains the purpose of each directory under /trunk, that would basically give me an orientation to the repository layout.

All I could find was http://mono-project.com/Mono_Contribution_HOWTO which doesn't really explain such things as what part(s) of the repository should be checked out to do basic things, or a policy on where things are to be checked-in, etc. Thankyou. -- View this message in context: http://www.nabble.com/SVN-Repository-layout---is-this-explained-anywhere-tp21772957p21772957.html Sent from the Mono - Dev mailing list archive at Nabble.com. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

[Mono-dev] Generic Variance
This patch adds generic variance support to the C# compiler. This patch does
not fully support the spec in that it provides variance only for reference
types. This limitation is designed to reflect the current (proposed) level
of variance support in the VM. New error codes are defined and tests for
each code are provided, as well as tests for variance. This patch is
contributed under the MIT/X11 license. It is attached.
NOTE: This email is a re-send. The original also had the patch inline, but
it was too long for the system. Blarg.

Re: [Mono-dev] SVN Repository layout - is this explained anywhere
Shane Moore wrote: Apologies to those who have an intimate understanding of the SVN repository. I have been considering helping with developing mono, but the main inhibition at this stage is to know where to find things, becuase the SVN repository has sooo many folders. I don't know where to start to find what. So I was wondering if anyone can point me to a document/page that explains the purpose of each directory under /trunk, that would basically give me an orientation to the repository layout. Or if such a document doesn't exist, could someone consider making such a document? - I don't expect a huge thing, possibly just a few short words to explain the purpose of each directory, e.g. what is the purpose of DemoLib, what is the purpose of Deveel.Pim, what is the purpose of Dumbarton, etc. If you want to contribute to mono, only 2-4 projects are relevant: http://mono-project.com/Compiling_Mono_From_SVN The incubator of .NET 3.x features (not mentioned on this wiki page) is called olive. Note that, IIRC, the repository protocol has changed from http to svn, so the links mentioned on the wiki page must start with svn://.

Re: [Mono-dev] high precision real cpu time in MONO (on linux)
You can use P/Invoke to call those functions.

The linux system call is clock_gettime. Apparently mono has some way to get it, since mono-2.2 contains the file mono/utils/mono-time.[ch] with functions gint64 mono_100ns_ticks(void) MONO_INTERNAL; gint64 mono_100ns_datetime (void) MONO_INTERNAL; I blindly guess that MONO_INTERNAL would mean that these functions are not accessible from C# 3.0 code. What is the easiest way to get high precision (at least high resolution) time on Linux? Ideally I would like to get CLOCK_REALTIME or CLOCK_MONOTONIC and CLOCK_THREAD_CPUTIME_ID. But any way of measuring milliseconds real cpu (preferably thread) time is ok. Any clues?

Can someone please help me with that? The way this is usually done is by building the assembly as a noinst_DATA target and adding something like: install-data-local: $(GACUTIL) /i $(ASSEMBLY) /f || exit 1; uninstall-local: $(GACUTIL) /u $(ASSEMBLY_NAME) /f || exit 1; ASSEMBLY_NAME is the name of your assembly without the .dll extension.
