I've hit this sort of errors a few times(libreoffice mainly), no need |
| 11 |
for blender experts. |

The problem is your when linking the libraries/binaries, it is trying |
| 13 |
to link code compiled with -std=c++11 and some library compiled with an |
| 14 |
older standard,and thus it the linker cannot find binary code that |
| 15 |
maches what your newly compiled programs wants. there was a news item |
| 16 |
about this, you should read/revisit it, named: |
| 17 |
Title GCC 5 Defaults to the New C++11 ABI |

The proposed solution is: |
| 23 |
(quote from the news item) |
| 24 |
For gentoolkit-0.3.1 or higher: |
| 25 |
# revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc |
| 26 |
|
| 27 |
For previous versions of gentoolkit: |
| 28 |
# revdep-rebuild --library 'libstdc\+\+\.so\.6' -- --exclude gcc |
| 29 |
|
| 30 |
But I've encountered some packages that weren't rebuild with that, so |
| 31 |
what I do is: search for the library that needs rebuild(hint e.g. for |
| 32 |
your case, eix imf) and then emerge -av1 that library, and try again |
| 33 |
rebuilding the package I wanted in the first place(blender for you). I |
| 34 |
say rebuild but I really just manually call ´ebuild $PORDTDIR/cat/pkg- |
| 35 |
ver' install as the portage user, and then package, and install it as a |
| 36 |
binary at the end, but how to do this is out of the scope of the |
| 37 |
interest of this thread. |
| 38 |
BTW, eix won't help you here, I tried it, so the next step is to find |
| 39 |
what provides the symbol 'Imf_2_1::Header::view', after some searches |
| 40 |
with find and then google, I arrived at opencv(though not 100% sure), |
| 41 |
so you might need to rebuild that and make sure(read the log) g++ is |
| 42 |
being called with std=c++11. tracking this sort of stuff might be |
| 43 |
tricky. |
