Description Philip Chimento 2010-06-23 21:43:33 UTC

Description of problem:
When compiling a program using SDL_mixer, linking halted, complaining about not being linked to -lm.

Version-Release number of selected component (if applicable):
1.2.11-2

How reproducible:
Compile a program which includes
PKG_CHECK_MODULES([WHATEVER], [SDL_mixer])
in its configure.ac.

Steps to Reproduce:
see above
  
Actual results:
/usr/bin/ld: /usr/lib/libSDL_mixer.so: undefined reference to symbol 'pow@@GLIBC_2.0'
/usr/bin/ld: note: 'pow@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line

Expected results:
no error

Additional info:
Can be solved by adding
WHATEVER_LIBS="$WHATEVER_LIBS -lm"
to configure.ac.

Note that the -lm does not need to be present in pkg-config, instead SDL_mixer itself should be directly linked against -lm.

I'll take care of fixing this.

A fixed build is on its way to rawhide. I've also filed an upstream bug for this:

Hi,

It really is not necessary to do an F-13 update for this, as it only causes
problems when compiling things and people compiling things / other packages which do need to issue an update for F-13 should be able to work around this easily.

Regards,

Hans

Ok, thanks for taking care. I will revoke the update then.
