[Comment 3 tman 2014-07-14 07:53:13 UTC]

the workaround: downgrading to version dev-cpp/gflags-2.0-r1.

so please fix the incompatibility please

[Comment 4 Marien Zwart (RETIRED) 2014-07-14 14:09:52 UTC]

gflags-2.1.1 switched build systems and no longer installs libgflags.so (just libgflags.a, libgflags.so.2.1.0 and libgflags.so.2). This looks like a bug in the gflags ebuild and/or build system rather than in glog.

[Comment 7 Adam Stylinski 2014-07-15 14:33:42 UTC]

This should be reopened, the libgflags shared lib being produced exports zero symbols:

adam@eggsbenedict ~ $ nm -gC /usr/lib64/libgflags.so.2.1.1
nm: /usr/lib64/libgflags.so.2.1.1: no symbols

The ebuild should be modified to use the cmake-utils in portage and pass the -DBUILD_SHARED_LIBS=ON flag to cmake.  Doing the gflags build locally with cmake on my machine with this use flag produces a proper shared lib (and doing it without it produces a static one).

adam@eggsbenedict ~/scratch/gflags-2.1.1 $ nm -gC lib/libgflags.so | wc -l
226

Ahh it turns out this is not very indicative of anything considering nm doesn't work on stripped binaries.  There is a linking error with blender and the SetCommandLineOption(char const*, char const*) function call, I'm tracking it down right now.

[Comment 9 Adam Stylinski 2014-07-15 21:26:59 UTC]

So as it turns out the issue is related to the fact that gflags recently switched to cmake and doesn't maintain pkg-config .pc files anymore.  I'm messing with the blender ebuild to fix this, but this is not currently an issue with libgflags.

not really a dupe, but that one has more information.
