Hi, after trying to get FreeCAD working and after getting some success (it runs when started by root) I decided to recompile the whole stuff from ground up to prevent to previously have a success by random, which turns into an error later.
I emerged -C freecad and cleanup the rest. I even removed according files below /usr/portage/distfiles to really get "the pure geniune experience"... ...it purely fails. vtk does not longer compile. It tried it with "factory setting" and with use flags, which I found on the internet when searching for "FreeCAD compile problems". Both failed the same way. I checked for enough space on my hd and yes...it is enough. Here is what I got: tmp/portage/sci-libs/vtk-7.1.0/work/vtk-7.1.0_build/Parallel/Core -I/var/tmp/portage/sci-libs/vtk-7.1.0/work/VTK-7.1.0/Parallel/Core -I/var/tmp/portage/sci-libs/vtk-7.1.0/work/vtk-7.1.0_build/IO/Legacy -I/var/tmp/portage/sci-libs/vtk-7.1.0/work/VTK-7.1.0/IO/Legacy -I/var/tmp/portage/sci-libs/vtk-7.1.0/work/vtk-7.1.0_build/Utilities/HashSource -I/var/tmp/portage/sci-libs/vtk-7.1.0/work/VTK-7.1.0/Utilities/HashSource -D__STDC_CONSTANT_MACROS -D_UNICODE -DNDEBUG -march=native -O2 -pipe -fPIC -fvisibility=hidden -o CMakeFiles/vtkIOParallelXML.dir/vtkXMLPUniformGridAMRWriter.cxx.o -c /var/tmp/portage/sci-libs/vtk-7.1.0/work/VTK-7.1.0/IO/ParallelXML/vtkXMLPUniformGridAMRWriter.cxx CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONFeature.cxx.o: In function `(anonymous namespace)::operator<<(vtkOStreamWrapper&, Json::Value const&)': vtkGeoJSONFeature.cxx:(.text+0x107): undefined reference to `Json::StyledStreamWriter::StyledStreamWriter(std::string)' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONFeature.cxx.o: In function `vtkGeoJSONFeature::ExtractGeoJSONFeatureGeometry(Json::Value const&, vtkPolyData*)': vtkGeoJSONFeature.cxx:(.text+0x2d4f): undefined reference to `Json::Value::asString() const' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONFeature.cxx.o: In function `vtkGeoJSONFeature::ExtractGeoJSONFeature(Json::Value const&, vtkPolyData*)': vtkGeoJSONFeature.cxx:(.text+0x3444): undefined reference to `Json::Value::asString() const' vtkGeoJSONFeature.cxx:(.text+0x3e9d): undefined reference to `Json::Value::asString() const' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONFeature.cxx.o: In function `vtkGeoJSONFeature::PrintSelf(std::ostream&, vtkIndent)': vtkGeoJSONFeature.cxx:(.text+0x448c): undefined reference to `Json::StyledStreamWriter::StyledStreamWriter(std::string)' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONReader.cxx.o: In function `vtkGeoJSONReader::GeoJSONReaderInternal::ParseFeatureProperties(Json::Value const&, std::vector<vtkGeoJSONReader::GeoJSONReaderInternal::GeoJSONProperty, std::allocator<vtkGeoJSONReader::GeoJSONReaderInternal::GeoJSONProperty> >&, char const*)': vtkGeoJSONReader.cxx:(.text+0xbb3): undefined reference to `Json::Value::operator[](std::string const&) const' vtkGeoJSONReader.cxx:(.text+0xc07): undefined reference to `Json::Value::asString() const' vtkGeoJSONReader.cxx:(.text+0xd9b): undefined reference to `Json::FastWriter::write(Json::Value const&)' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONReader.cxx.o: In function `vtkGeoJSONReader::GeoJSONReaderInternal::ParseRoot(Json::Value const&, vtkPolyData*, bool, char const*)': vtkGeoJSONReader.cxx:(.text+0x1897): undefined reference to `Json::Value::asString() const' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONReader.cxx.o: In function `vtkGeoJSONReader::GeoJSONReaderInternal::CanParseFile(char const*, Json::Value&)': vtkGeoJSONReader.cxx:(.text+0x25ee): undefined reference to `Json::Reader::getFormattedErrorMessages() const' CMakeFiles/vtkIOGeoJSON.dir/vtkGeoJSONReader.cxx.o: In function `vtkGeoJSONReader::GeoJSONReaderInternal::CanParseString(char*, Json::Value&)': vtkGeoJSONReader.cxx:(.text+0x2a66): undefined reference to `Json::Reader::parse(std::string const&, Json::Value&, bool)' vtkGeoJSONReader.cxx:(.text+0x2c74): undefined reference to `Json::Reader::getFormattedErrorMessages() const' collect2: error: ld returned 1 exit status make[2]: *** [IO/GeoJSON/CMakeFiles/vtkIOGeoJSON.dir/build.make:156: lib/libvtkIOGeoJSON.so.1] Error 1 make[2]: Leaving directory '/var/tmp/portage/sci-libs/vtk-7.1.0/work/vtk-7.1.0_build' make[1]: *** [CMakeFiles/Makefile2:5039: IO/GeoJSON/CMakeFiles/vtkIOGeoJSON.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs....

When you file a bug report, please include the following information: GENTOO_VM= CLASSPATH="" JAVA_HOME="" JAVACFLAGS="" COMPILER="" If needed I will post all log etc...but I dont want to logbomb the mailinglist in beforehand ;) Thank you very much for any help in advance!
