Bug 508132 – media-sound/timemachine - ld: meters.o: undefined reference to symbol 'log10@@GLIBC_2.2.5'

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Stefan Richter 2014-04-19 17:14:10 UTC]

Emerging media-sound/timemachine-0.3.1 and media-sound/timemachine-0.3.3 breaks with:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/bin/ld: meters.o: undefined reference to symbol 'log10@@GLIBC_2.2.5'
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/bin/ld: note: 'log10@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try adding it to the linker command line
/lib64/libm.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make[2]: *** [timemachine] Error 1


Reproducible: Always




Seen on amd64 with
    sys-devel/gcc-4.7.3-r1
    sys-libs/glibc-2.17
    dev-libs/glib-2.38.2-r1:2
    x11-libs/gtk+-2.24.23:2
    media-sound/jack-audio-connection-kit-0.121.3-r1
    media-libs/libsndfile-1.0.25-r1
but certainly not entirely specific to those versions.

[Comment 1 Stefan Richter 2014-04-19 17:27:54 UTC]

unsurprisingly, reproduced on x86-32

[Comment 2 Stefan Richter 2014-04-21 08:48:06 UTC]

Re blocking bug 372079:  Indeed, it still builds with =sys-devel/binutils-2.23.1 but fails to build with =sys-devel/binutils-2.23.2.
