Can compile with binary compile file but not from compile command

Closed this issue 4 years ago · 1 comments

If I run ./compile I can successfully compile extract_mvs.c but if I run the command included in the compile_commands.txt file gcc -o extract_mvs extract_mvs.c -lavcodec -lavformat -lavutil -lavdevice -lswresample -lswscale -L/opt/dev-tools-sources/ffmpeg/build/lib -I/opt/dev-tools-sources/ffmpeg/build/include -l json -w
I get the following error:
ld: library not found for -ljson clang: error: linker command failed with exit code 1 (use -v to see invocation)
I am on MacOS.

Hi @fbordwell, from the error, it seems that the JSON library is not installed on your system. Please try to install it and see if that works. I have not worked on macOS so I am afraid I can't help in that context. Feel free to revert back.
