[Comment 1 Johan Bergström 2012-10-17 03:23:53 UTC]

What version of libmemcached are you building against?

[Comment 2 Johan Bergström 2012-10-17 03:28:01 UTC]

This occurs with libmemcached 0.12. It seems to be an upstream bug:
libmemcached-1.0/configure.h:#define LIBMEMCACHED_VERSION_HEX @PANDORA_HEX_VERSION@

[Comment 3 Ian Delaney (RETIRED) 2012-11-13 14:43:39 UTC]

# USE_PYTHON="2.5 2.6 2.7-pypy-1.9" ebuild pylibmc-1.2.3.ebuild clean install
Writing /mnt/gen2/TmpDir/portage/dev-python/pylibmc-1.2.3/temp/images/2.7-pypy-1.9/usr/lib64/pypy1.9/site-packages/pylibmc-1.2.3-py2.7.egg-info

built fine here. libmemcached 0.12 would be 2007-8 vintage.

This
x86_64-pc-linux-gnu-gcc -pthread -march=athlon64 -pipe -fomit-frame-pointer -O2 -fPIC -DUSE_ZLIB -I/usr/include/python2.6 -c _pylibmcmodule.c -o build-2.6/temp.linux-x86_64-2.6/_pylibmcmodule.o -fno-strict-aliasing

is the line where it trips.  I can display the 'what' but certainly not the 'why'
from above traceback; "token "@" is not valid in preprocessor expressions"
unless I'm missing something,

 # grep "@" /mnt/gen2/TmpDir/portage/dev-python/pylibmc-1.2.3/work/pylibmc-1.2.3/{_pylibmcmodule.h,_pylibmcmodule.c}

yields blank.  In the build that fails the preprocessor expressions appear to feature token '@', build in my system they're absent.  Someone knowing more than I can give this more meaning.

I'm not sure what you're talking about here. As I already noted, it's from a bad m4 expansion (It never expanded).

My above comment was a typo - 0.12 should be 1.0.12. The bug Patrick is hitting was notified upstream and was fixed in 1.0.13 (couldn't find the bug I filed in launchpad for whatever reason). You can find the patch at our bugzilla here: https://bugs.gentoo.org/show_bug.cgi?id=438166

Since we don't have 1.0.12 in tree, this bug should probably be closed anyway.

[Comment 5 Johan Bergström 2012-11-14 05:38:41 UTC]

Closing - libmemcached 1.0.12 not in tree and bug is filed against pylibmc.
