Whether I work from the 0.48 source download or from the bazaar download my compiles blow up at the same point: ------------------------------- libinkscape.a(nr-filter-gaussian.o): In function `_ZN8Inkscape7FiltersL12filter2D_FIRIhLj4EEEvPT_iiPKS2_iiiiPKNS_4Util10FixedPointIjLj16EEEii.omp_fn.5': /usr/local/inkscape/src/display/nr-filter-gaussian.cpp:371: undefined reference to `void Inkscape::Filters::filter2D_FIR<unsigned char, 4u>(unsigned char*, int, int, unsigned char const*, int, int, int, int, Inkscape::Util::FixedPoint<unsigned int, 16u> const*, int, int)::C.639' libinkscape.a(nr-filter-gaussian.o): In function `_ZN8Inkscape7FiltersL12filter2D_FIRIhLj3EEEvPT_iiPKS2_iiiiPKNS_4Util10FixedPointIjLj16EEEii.omp_fn.4': /usr/local/inkscape/src/display/nr-filter-gaussian.cpp:371: undefined reference to `void Inkscape::Filters::filter2D_FIR<unsigned char, 3u>(unsigned char*, int, int, unsigned char const*, int, int, int, int, Inkscape::Util::FixedPoint<unsigned int, 16u> const*, int, int)::C.622' collect2: ld returned 1 exit status make[3]: *** [inkscape] Error 1 make[2]: *** [all] Error 2 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 ------------------------------------------ Obviously there is something screwed up on my system that ./configure fails to catch. Can anyone suggest where this screw up might be? I have no problem with downloading and installing another or newer library but which one has the Gaussian filter stuff?
