• Error inclunding in FFMPEG project on a Mac using clang

  3 juillet 2018, par benwiz

  I’m having trouble running the remuxing.c example code. I get the following error. I have confirmed that the files can be found in /usr/local/include. I am running macOS Sierra 10.12.6.

  clang: error: linker command failed with exit code 1 (use -v to see invocation)

• ffmpeg - conflicting libraries or unable to compile C++ project [duplicate]

  2 octobre 2020, par QRrabbit

  This is less about C++, and more about specific compiling avcodec and avformat as those are used inside FFmpeg. I'm trying to compile for the first time newly downloaded ffmpeg source. All the linking has been resolved, and the program errors on this specific allocation.

  


  I'm writing my first program - attempt at avformat libraries inside my C++ code. Linker errors on this line :

  


  [ 89%] Linking CXX executable ffmpeg_01
clang: error: no such file or directory: 'VideoToolbox'
clang: error: no such file or directory: 'CoreFoundation'
clang: error: no such file or directory: 'CoreMedia'
clang: error: no such file or directory: 'CoreVideo'
clang: error: no such file or directory: 'CoreServices'
clang: error: no such file or directory: 'OpenGL'
clang: error: no such file or directory: 'CoreImage'

clang: error: no such file or directory: 'CoreAudio'
clang: error: no such file or directory: 'AVFoundation'
clang: error: no such file or directory: 'CoreGraphics'
make[3]: *** [ffmpeg_01] Error 1


  


  This is the content of my *libavcodec.pc file, and it has an entry of conflicts : which lists all of the items that clang cannot find, I don't know if those are linked somehow. I found a source pointing that similar error appears if I had other forks of ffmpeg, but I do not.

  


  prefix=/usr/local
exec_prefix=${prefix}
libdir=/usr/local/lib
includedir=/usr/local/include

Name: libavcodec
Description: FFmpeg codec library

  I don't have experience in cmakefile, I can paste it here if needed.
Any help is greatly appreciated, because I'm stuck for the past several days.
