I have tried the .gz download, the .bz2 download, and even the bazaar version. 0.47 configures and compiles with no problem. All versions of 0.48 blow up at the same spot:

I use Linux Slackware 13.0. I have posted several times on the user mail list but no useful hints are forthcoming. My gcc is version 4.3.3.

It appears to be a bug in GCC's implementation of OpenMP. The linker can't find functions referenced from OpenMP-generated code. That's because the qualifiers on one of the function parameters are incorrect. The error message mentions: Inkscape::Util::FixedPoint<unsigned int, 16u> const* The correct type of this parameter is: Inkscape::Util::FixedPoint<unsigned int, 16u> const* const

You could try manually changing line 353 of src/display/nr-filter-gaussian.cpp from: int const n1, int const n2, FIRValue const *const kernel, int const scr_len, int const num_threads) to: int const n1, int const n2, FIRValue const *kernel, int const scr_len, int const num_threads) See if that allows the linking to complete. If it does, we might incorporate this workaround into 0.48.1.
