UNIX_import pyplot:_path.so: symbol _ZNSs4_Rep20_S_empty_rep_storageE:referenced symbol not found


my message is related to this thread:


because i encountered the same problem, and found a workaround, hope this help:

  • i’m using solaris/opensolaris/solaris11express (the name is changing often…), say sunos5

  • i compiled numpy and matplotlib with oracle studio (ex sunstudio), available for free

  • when i got these errors:

ldd -d ./build/lib.solaris-2.11-i86pc-2.6/matplotlib/_delaunay.so

libpython2.6.so.1.0 => /usr/lib/libpython2.6.so.1.0

symbol not found: 1cDstdZ__RTTI__1nDstdJbad_alloc (./build/lib.solaris-2.11-i86pc-2.6/matplotlib/_delaunay.so)

i found that the problem is missing libs, so i re-start the compil line like this:

/usr/lib/python2.6/pyCC -G build/temp.solaris-2.11-i86pc-2.6/lib/matplotlib/delaunay/_delaunay.o build/temp.solaris-2.11-i86pc-2.6/lib/matplotlib/delaunay/VoronoiDiagramGenerator.o build/temp.solaris-2.11-i86pc-2.6/lib/matplotlib/delaunay/delaunay_utils.o build/temp.solaris-2.11-i86pc-2.6/lib/matplotlib/delaunay/natneighbors.o -L/opt/solstudio12.2/lib -lpython2.6 -o build/lib.solaris-2.11-i86pc-2.6/matplotlib/_delaunay.so -lCstd -lCrun

just adding -lCstd -lCrun, and everything is now ok!

i don’t understand why setupext.py forgot to do this, even after modified it:
