Any suggestions?

[steppicrew]

I had the same problem here.

Try to rebuild media-libs/libraw

[helio]

Thanks, steppicrew! That indeed solved the problem. I also found the same solution in a previous post in this forum.

[dataking]

Just adding a +1 here.

Rebuilt media-libs/libraw then emerge broken libs (forget the exact command, atm) and things seem to work.

Thanks for the post!

I have the same problem, but emerging libraw doesn't fix it. I found the OMP library at /usr/lib64/gcc/x86_64-pc-linux-gnu/4.8.3, so I did
export LDPATH="/usr/lib64/gcc/x86_64-pc-linux-gnu/4.8.3/libgomp.so.1"

also

export LDPATH="/usr/lib64/gcc/x86_64-pc-linux-gnu/4.8.3/"

Also changed /etc/portage/make.config to add -L to CFLAGS:

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
CFLAGS="-march=native -O2 -pipe -L/usr/lib64/gcc/x86_64-pc-linux-gnu/4.8.3/"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j5"

What am I doing wrong?

[steveL]

Have you switched compiler with gcc-config? You need to source the profile and env-update after to work from the same terminal.

Also check the content of /etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf to make sure the right ordering is in-place (the compiler you've switched to/are running, first.)

[davidjtanner]

gcc-config was pointing to gcc version 4.7.3. Changed it. Link still fails with the same undefined symbols.

Forgot to affirm that I logged off and on after I did gcc-config and env-update. ./etc/profile gave "permission denied".
I am running linux in VirtualBox under Win7. I am building in a terminal window under kde having done su.
I am an experienced sw engineer, but not as experienced with Linux as I am trying to become.

OK, since you've just switched compiler, try the following:
