test_mp3

Task description you can find in Task.md

• src - source dir
• test_wav - set of test wav-files (Downloaded from https://freesound.org/ - free or NonCommercial License)
• recompile_autotools_with_hack.sh - compile project by autotools. Contains one hack (./configure && make - doesn't work).

I want to link libmp3lame statically, but pthread dynamically. If I add libmp3lame with -Wl,-Bstatic to LDFLAGS, then ldd cannot link libmp3lame. libmp3lame should to specify in LDADD, but autotools does not allow it. If I add LDADD as a comment to src/Makefile.am, then it will also get added into the resulting Makefile as a comment. So I simply uncomment this string after configure script and as a result, statically linked libmp3lame is appended to LDADD

• result file testmp3. To run the tests, run testmp3 ./test_wav
