The problem is your when linking the libraries/binaries, it is trying to link code compiled with -std=c++11 and some library compiled with an older standard,and thus it the linker cannot find binary code that maches what your newly compiled programs wants. there was a news item about this, you should read/revisit it, named: Title GCC 5 Defaults to the New C++11 ABI Author Mike Frysinger <[email protected]> Posted 2015-10-22 Revision 2
The proposed solution is: (quote from the news item) For gentoolkit-0.3.1 or higher: # revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc For previous versions of gentoolkit: # revdep-rebuild --library 'libstdc\+\+\.so\.6' -- --exclude gcc But I've encountered some packages that weren't rebuild with that, so what I do is: search for the library that needs rebuild(hint e.g. for your case, eix imf) and then emerge -av1 that library, and try again rebuilding the package I wanted in the first place(blender for you). I say rebuild but I really just manually call ´ebuild $PORDTDIR/cat/pkg- ver' install as the portage user, and then package, and install it as a binary at the end, but how to do this is out of the scope of the interest of this thread. BTW, eix won't help you here, I tried it, so the next step is to find what provides the symbol 'Imf_2_1::Header::view', after some searches with find and then google, I arrived at opencv(though not 100% sure), so you might need to rebuild that and make sure(read the log) g++ is being called with std=c++11. tracking this sort of stuff might be tricky.
