[UnAfraid]

Hello,
I am trying to compile telegram on my own, i've followed the guide for Visual Studio 2015 https://github.com/telegramdesktop/tdesktop/blob/master/doc/building-msvc.md

I've builded eveything successfully even fffmpg but when i had to configure and make with msys64 it failed
I did as shown here https://github.com/telegramdesktop/tdesktop/blob/master/doc/building-msvc.md#ffmpeg

PATH="/c/Program Files (x86)/Microsoft Visual Studio 14.0/VC/BIN:$PATH"

cd /d/TBuild/Libraries/ffmpeg
pacman -Sy
pacman -S msys/make
pacman -S mingw64/mingw-w64-x86_64-opus
pacman -S diffutils
pacman -S pkg-config

Logs

I got an error:
```cl is unable to create an executable file.
If cl 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
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

The console.log:

I had the same problem.

The instructions are not very clear, but you have to open msys from the VS2015 x86 Native Tools Command Prompt.

[UnAfraid]

@BlackLanzer thanks that worked!

[auchri]

"not very clear"? xD

All commands (if not stated otherwise) will be launched from VS2015 x86 Native Tools Command Prompt.bat (should be in Start Menu > Programs > Visual Studio 2015 menu folder).

[BlackLanzer]

Go to D:\msys64 and launch msys2_shell.bat, there run

In my opinion it looks like you can run it without the native tools.

Create a PR and make it better ;)

I have the same problem but the difference is that there is no such msys2_shell.bat file. there is msys2_shell.cmd which opens new command prompt window with msys2 style.
This msys2_shell.bat has been removed from msys2 and replaced with msys2_shell.cmd. what should we do ?

@ray-pixar

_In instructions:_ launch msys2_shell.bat

This msys2_shell.bat has been removed from msys2 and replaced with msys2_shell.cmd

What do you think?

But to be serious, I guess PR would be welcome.

[Behrouz-m]

what is PR ?

[Behrouz-m]

I'm getting this error in config.log:

LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'

[Behrouz-m]

now I am getting this error:

ERROR: opus not found using pkg-config

[BestHelloWorld]
