FFmpeg build issues

[CoBC]

Hi,
after recent merges to master branch, I had to rebuild again (because CMake was automatically ran).
Unfortunately, I have the following issue regarding FFmpeg:
" Performing build step for 'ffmpeg-src'
cl.exe is unable to create an executable file.
If cl.exe is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

Code 1. [C:\Git\TeamTalk5\Build\out64\Library\TeamTalkLib\build\ffmpeg\ffmpeg-src.vcxproj]"

Anyone has an idea?

Thanks.

Try deleting C:\Git\TeamTalk5\Build\out64\Library\TeamTalkLib\build\ffmpeg so it will trigger a new build of FFmpeg.

I'm also experiencing some build issues when building FFmpeg for Win32 (x86):

       "C:\tt5dist\TeamTalk5_x86\TeamTalk5\Build\build-win32\Library\TeamTalkLib\TeamTalk5DLL.vcxproj" (default target) (12) ->

Strangely this doesn't occur on GitHub.

[CoBC]

Doesn't occur on GitHub, and doesn't occured before merges to master.
Already tried to delete folder you mentioned, with same error on rebuild. Also tried to rebuild from scratch.
log file mentioned invalid or corrupted object for test.o (LNK1136)

If you're running the x64_x86 cross compiler, try switching to the x86 native tools. If not, try the opposite. That might solve the problem. I'll look into it in a few days.

[CoBC]

Still the same issue forme me with master branch. I tried switching to x86_64 cros tool, and x64 native tools, with same result :(

[hwangsihu]

Can you try debug-windows-cross branch?

[CoBC]

Hi,
I tried debug-windows-cross branch with x64_x86 cross compil tool with the same result

[hwangsihu]

Yes, I checked yesterday as well, but it failed. I'll have to try a different method.

[hwangsihu]

@CoBC, Can you retry?

[CoBC]

Yes! It works
