    Le précédent commit autorisait à saisir les valeurs min/max d’un nombre
    décimal en mettant une virgule plutôt qu’un point.
    Il faut donc qu’on puisse tester à partir de ces valeurs avec virgule…

  • How do I write a batch file that opens a msys shell and then run commands in the shell ?

    19 septembre 2024, par cxu

    I'm trying to automate the process of building ffmpeg on Windows 10. I'm following the guide here : https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC

    



    Everything works fine when I do it manually, however I want to write a batch file that I can run to go through the entire process automatically.

    



    Building requires me to set up the Visual Studio environment and the MSYS environment. This is where I'm having trouble, since running the MSYS environment opens up a new shell. I want to pass the configure/make/make install commands to the MSYS shell after it is opened.

    



    I've tried the solution here : How to open a new shell in cmd,then run script in a new shell ?

    



    The problem they had looks similar to mine, but the solutions posted there didn't work for me.

    



    Here is the bat file currently :

    



    call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64\vcvars64.bat"
call "C:\workspace\windows\mingw-get\msys\1.0\msys.bat" start cmd.exe /k bscript
pause


    



    and bscript :

    



    ./configure --enable-shared --toolchain=msvc --arch=amd64
make
make install


    



    I've tried all sorts of variations like :

    



    call "C:\workspace\windows\mingw-get\msys\1.0\msys.bat" /k bscript
call "C:\workspace\windows\mingw-get\msys\1.0\msys.bat" bscript
start "C:\workspace\windows\mingw-get\msys\1.0\msys.bat" /k bscript
start "C:\workspace\windows\mingw-get\msys\1.0\msys.bat" bscript


    



    And I've also tried leaving the bscript code in the original batch file.

    



    The configure/make commands will either run in the original cmd window, a new cmd window or wont run at all.

    



    Is there a way to pass commands to the MSYS shell like that ?
