Description

Previously already reported in the other VVCSoftware_VTM bug tracker which does not seem to be maintained actively, though...


Thanks to the media-autobuild_suite I already enjoy building a variety of video and audio software in a regularly updated MSYS2 environment with MinGW32 (GCC 7.3.0) and MinGW64 (GCC 8.2.0).

So I tried to use it to build VVCSoftware_VTM as well. Unfortunately, using CMake to generate "MSYS Makefiles", BBuildEnv reported a warning:

-- Setting up BBuildEnv 3.10.2.4
CMake Warning at cmake/CMakeBuild/cmake/modules/BBuildEnv.cmake:1037 (message):
  BBuildEnv.cmake: generator 'MSYS Makefiles' is not fully supported yet,
  please contact technical support for further information.
Call Stack (most recent call first):
  cmake/CMakeBuild/cmake/modules/BBuildEnv.cmake:1084 (bb_build_env_setup)
  CMakeLists.txt:52 (include)

Trying to make it anyway failed:

Are the sources too specifically MSVC optimized?

A few thoughts about the problems arising, posted by e.g. SmilingWolf, can be read in this doom9 forum thread. He managed to build the software single-threaded. But with your insight I believe a better adaption is possible.

  • Version changed from VVC D3 v1 to VTM-2.2

A patch by Karsten Suehring enables building the applications in MSYS2 with MinGW32 (GCC 7.3.0) and with MinGW64 (GCC 8.2.0).

Merge request 120: Update cmake environment

Issue can be closed after merging, I believe...
