Audacious Plugins Fails to Link mpg123 module #25

Open dslm4515 opened 2 years ago

When compiling:

Checking the installed mpg123 library:

$ readelf -s /usr/lib/libmpg123.so.0.46.7 | grep mpg123_open

I noticed when building this CFLAG when mpg123 was built:

CFLAGS="-D_FILE_OFFSET_BITS=64"

I forgot why this flag was used. If ommited then mpg123 builds its library with these symbols instead:

$ readelf -s libmpg123* | grep mpg123_open

Should i remove that flag?

Not sure what required those symbols to require those '_64' suffixes...

dslm4515 commented 2 years ago

Rebuilt mpg123 (with out the offset_bits set to 64) and installed it in /opt/mpg123 and prefixed configure command for audacious-plugins to use newly bilt mpg123:

MPG123_CFLAGS="-I/opt/mpg123/include"  MPG123_LIBS="/opt/mpg123/lib/libmpg123.so -lmpg123 "

Now audacious-plugins builds without error.

gst-plugins-good would compile but fail to link because symbols from mpg123 were not suffixed with _64
