• Need help to compile FFmpeg with MSVC tools

  30 janvier 2018, par Antwane

  I need to compile FFmpeg on Windows 10 using MSVC 2017 compiler. I followed some guides from :

  • https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC
  • https://www.ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b-or-Intel-C_002b_002b-Compiler-for-Windows
  • https://pracucci.com/compile-ffmpeg-on-windows-with-visual-studio-compiler.html

  I installed current stable version of MSYS, fixed link.exe and use of PATH environment, installed make diffutils gcc pkg-config and downloaded c99-to-c89, nasm, and inttypes.h

  I think my environment is now correctly set up, I ran MSYS shell from MSVC Command prompt and have everything reachable.

  $ which cl
  
  /c/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.12.25827/bin/HostX64/x64/cl
  
  
  
  $ which link
  
  /c/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.12.25827/bin/HostX64/x64/link
  
  
  
  $ which yasm
  
  /home/Antoine/bin/yasm
  
  
  
  $ which c99conv
  
  /home/Antoine/bin/c99conv
  
  
  
  $ which c99wrap
  
  /home/Antoine/bin/c99wrap

  Now I configure the build

  $ ./configure --toolchain=msvc

  perl enabled              no
  
  pod2man enabled           no
  
  makeinfo enabled          no

  Programs:

  [...]
  
  Hundreds of modules, library, etc.
  
  [...]
  
  
  
  License: LGPL version 2.1 or later
  
  Creating configuration files ...
  
  config.h is unchanged
  
  config.asm is unchanged
  
  libavutil/avconfig.h is unchanged
  
  libavcodec/bsf_list.c is unchanged
  
  libavformat/protocol_list.c is unchanged

  But when I run make it stops very quickly

  $ make
  
  Makefile:47: la cible « qt-faststart » ne correspond pas au motif de cible
  
  Makefile:47: la cible « trasher » ne correspond pas au motif de cible
  
  Makefile:47: la cible « uncoded_frame » ne correspond pas au motif de cible
  
  Makefile:91: ffbuild/library.mak: No such file or directory
  
  make: *** Aucune règle pour fabriquer la cible « ffbuild/library.mak ». Arrêt.

  Sorry for the french wording, I don’t know how to tell MSVC print its output in english. Basically, the error means :

  Makefile:47: target « qt-faststart » doesn't match the target pattern
  
  make: *** No rule to make target « ffbuild/library.mak ». Stopped.

  Side notes :

  $ tree ffbuild
  
  ffbuild
  
  ├── config.fate
  
  ├── config.log
  
  ├── config.mak
  
  └── config.sh

  That’s right, library.mak were not generated into ffbuild, but I don’t know why, and configure script didn’t output any error message...

  Does anybody can help me to find out what am I doing wrong ?

  Edit :

  make distclean doesn’t help

  $ make distclean
  
  Makefile:47: la cible « qt-faststart » ne correspond pas au motif de cible
  
  Makefile:47: la cible « trasher » ne correspond pas au motif de cible
  
  Makefile:47: la cible « uncoded_frame » ne correspond pas au motif de cible
  
  Makefile:91: ffbuild/library.mak: No such file or directory
  
  make: *** Aucune règle pour fabriquer la cible « ffbuild/library.mak ». Arrêt.
