Ok, I see. So we need a working version of cccl or a replacement. I try to make a deeper look into this issue.

Hi Matthias!

Ok, I have tried that cccl script, but it still fails miserably to even build libtool. So naturally I have no testsuite results. The failure looks the same (on a cursory look) on master and on the pr-msvc-support branch so I do not appear to have made things worse...

This cccl script is not targeting MSYS (it uses single forward slashes) and can therefore only be used from cygwin. It is also a fact that this cccl script uses cygpath to convert incoming posix paths to windows paths, which libtool is also doing when cccl is detected on cygwin. That looks like a major incompatibilty to me. The provided ccclibtool wrapper isn't improving things for me.

I still need someone to show me a recipe for how to build libtool with (some incarnation of) cccl.

Cheers,
Peter

Peter, you have mentioned, that you wanted to test this path with cccl, but doesn't worked for you. I don't know if this is still an issue but there exists a new patch for cccl mentioned on this site: http://folti.blogs.balabit.com/2009/08/compiling-autoconfmake-using-sources.html
source code can be downloaded from
$ git clone git://git.balabit.hu/folti/cccl.git

I hope this helps to improve the MSVC support, because for now this is a must have to introduce the use of open source libraries in our company!

Cheers,
Matthias

Thanks! But don't hesitate to report back if you don't have any issues... :-)

Peter, I've installed that patched libtool system-wide on gentoo/x86_64 laptop on which I'm doing my current gstreamer development, I'll be re-libtool everything with it and will report any issues.

Thanks very much for the feedback,

I'm glad to hear about the success! Previously there has been requests to test how this patch series behaves on other systems (which are not supposed to be affected). So, you can help by checking for regressions on whatever other systems you have available.

In particular, testing for regressions using the cccl script was requested, but I failed to get cccl to do anything useful in the libtool context. So, any cccl user out there could also help with testing.

I think the lib-as-archiver patches (i.e. 1/7 and 6/7) are the most intrusive in the series and they should perhaps be held back. IIRC, the patches work well with AR=ar as well, so that would not hinder using MSVC as the compiler/linker. You can test that as well, if you like. Leaving out AR=lib should be equivalent to saying AR=ar.

Cheers,
Peter

Hi, I'd like to give my feedback on these 7 patches (applied against trunk svn).

They work amazingly well, I have been compiling gstreamer and dependencies under msys using msvc... and I had to remove all the 'hacks' I previously added to the makefiles to make it compile properly.

Apart from being libtool-ized, they don't require ANY makefile/configure modification to be compiled with msvc under msys (thanks for fixing all the cygwin vs msys issues also).

Awesome work ! I don't know what more is needed to push these patches in, if you need more feedback, logs, etc... please ask.

I have no problems with this patch series on either mingw, nor
cygwin.

I have not found a functioning cccl to test with. I have tried
both cccl 0.03 as found on sf.net and cccl 0.05 as found on
http://tsunanet.net/~tsuna/cccl

Niether cccl can even build libtool. I have tried to patch
around the first few problems in cccl, but I can't see why
I should fix cccl in order to check if it these patches
break cccl. cccl is seriously broken, or please point me
to a version of cccl that I should use.

(I used cygwin and ../configure CC=cccl CXX=cccl LD=cccl F77=no FC=no GCJ=no)


Annotated testsuite with these patches:

On MSYS and MSVC 12.00.8804 (MSVC 6) with:
../configure CC=cl CFLAGS=-MD CXX=cl CXXFLAGS=-MD LD=link NM="dumpbin -symbols" AR=lib STRIP=: RANLIB=: F77=no FC=no

The problems with the exported variables can be solved with the
right amount of declspecs. I will not work on the other problems
until basic MSVC support is commited.

Add MSVC support. Some of this stuff would probably benefit
cccl, but I don't know what...
This patch is against Libtool 2.2

  • libltdl/m4/libtool.m4: Add support for Microsoft Visual C.
  • NEWS: Add note of the above.
