[FFmpeg-devel] Symbol versioning failure on Android
Mon Dec 6 23:33:13 CET 2010
If building shared libraries on Android, there seems to be a problem with
symbol versioning. The fallback symbols in the previous library, defined
e.g. in libavcodec/opt.c should call the new ones in libavutil/opt.c. In
practice, they just call themselves, looping infinitely.
Does anyone have better insight into the symbol versioning stuff, that
could point out what could be going wrong? Which part does the mapping of
the call to e.g. av_opt_set_defaults2 to either of the versioned symbols
in libavcodec.so and/or libavutil.so - is this up to the runtime dynamic
linker? According to nm -D, both of them have a defined symbol named
"av_opt_set_defaults2", likewise on normal desktop linux, too.
Should we add a configure option for disabling the symbol versioning?
