  • Linking libavcodec and libavformat : Undefined references

    8 décembre 2014, par Abhijit

    I am trying to compile a project I am working on that uses ffmpeg libraries. The project is written in C. The header files are appropriately included in the source code. In particular, it seems to be using libavcodec and libavformat, and these libraries are appropriately linked in the Makefile with the LDFLAGS. Here are the flags used :

    -lavcodec -lavformat -lswscale -lavutil

    Now, because the packaged libraries that come with Ubuntu were too out-of-date, I downloaded the latest source code for ffmpeg, compiled it and installed it. I removed all of the packaged libraries that were installed via the package manager. Now, despite adding the flags above, I get a lot of undefined references and I cannot seem to fix it. Here is the output with regard to the undefined references :
