All Rendering_Serial tests fail
System: Ubuntu 18.04 with gcc-7.3 Hardware: Intel i7-4710HQ with nvidia GTX-860m, Intel i5-7200u Compile: Serial only Symptom: All Rendering_Serial tests fail with error:
***** STL exception throw.
Unknown error -1
I traced it back to ColorTablePresets.cxx:GetColorTablePresetsVector. Compiling with my systems means pthreads is not linked with the Serial compilation, so std::call_once fails because it needs the pthread library. If I add -pthread to CMAKE_CXX_FLAGS, the Rendering_Serial tests generate images.
