Problem seems to be in libQt. Would it help switching the import order? import pylab import dolfin
Or there's conflicting Qt lib, check that DOLFIN and pylab link to the same: $ ldd /path/to/fenics/lib/libdolfin.so | grep -i qt $ # check pylab, don't know how Or you could recompile dolfin without Qt (it's practically useless dependecy, see plot-qt demo) by configuring with -DDOLFIN_ENABLE_QT:BOOL=OFF Jan On Thu, 15 Jan 2015 12:59:14 +0100 Steffen Wittek <[email protected]> wrote: > the stacktrace: > > gdb -ex r -ex bt -args python -c "from dolfin import *; import pylab > as py" [...] > Reading symbols from python...(no debugging symbols found)...done. > Starting program: /usr/bin/python -c from\ dolfin\ import\ \*\;\ > import\ pylab\ as\ py > warning: Could not load shared library symbols for linux-vdso.so.1. > Do you need "set solib-search-path" or "set sysroot"? > [Thread debugging using libthread_db enabled] > Using host libthread_db library "/usr/lib/libthread_db.so.1". > [New Thread 0x7fffb46df700 (LWP 732)] > > Program received signal SIGSEGV, Segmentation fault. > 0x00007ffff74df73a in __strcmp_sse2_unaligned () > from /usr/lib/libc.so.6 #0 0x00007ffff74df73a in > __strcmp_sse2_unaligned () from /usr/lib/libc.so.6 #1 > 0x00007fffa9ce009f in QMetaType::registerNormalizedType(QByteArray > const&, void (*)(void*), void* (*)(void const*), void (*)(void*), > void* (*)(void*, void const*), int, QFlags<QMetaType::TypeFlag>, > QMetaObject const*) () ---Type <return> to continue, or q <return> to > quit--- from /usr/lib/libQt5Core.so.5 > #2 0x00007fffaa0e91e1 in ??
