I recently updated cgm and tried building it as I had been, configuring with '/opt/contrib-clangcxx11/cmake-3.2.2-ser/bin/cmake' -DCMAKE_INSTALL_PREFIX:PATH=/opt/volatile-clangcxx11/cgm-master.r1494-ser -DCMAKE_BUILD_TYPE:STRING=Release -DCMAKE_COLOR_MAKEFILE:BOOL=FALSE -DCMAKE_VERBOSE_MAKEFILE:BOOL=TRUE -DBUILD_WITH_SHARED_RUNTIME:BOOL=TRUE -DCMAKE_C_COMPILER:FILEPATH='/usr/bin/clang' -DCMAKE_CXX_COMPILER:FILEPATH='/usr/bin/clang++' -DCMAKE_Fortran_COMPILER:FILEPATH='/opt/homebrew/bin/gfortran-4.9' -DCMAKE_C_FLAGS:STRING='-fPIC -pipe' -DCMAKE_CXX_FLAGS:STRING='-std=c++11 -stdlib=libc++ -fPIC -pipe' -DCMAKE_Fortran_FLAGS:STRING='-fPIC -pipe' -DOCE_DIR:PATH='/opt/volatile-clangcxx11/oce-OCE-0.17-txc.r1462-sersh/OCE.framework/Versions/0.17/Resources' /sources/projects/composerall/cgm The configure worked fine, but the build failed at /usr/bin/clang++ -std=c++11 -stdlib=libc++ -fPIC -pipe -O3 -DNDEBUG -dynamiclib -Wl,-headerpad_max_install_names -o ../lib/libcubit_util.dylib ... Undefined symbols for architecture x86_64: "CubitColor::CubitColor(unsigned char, unsigned char, unsigned char, unsigned char)", referenced from: __GLOBAL__sub_I_GfxDebug.cpp in GfxDebug.cpp.o "CubitColor::CubitColor()", referenced from: __GLOBAL__sub_I_GfxDebug.cpp in GfxDebug.cpp.o "CubitEvent::~CubitEvent()", referenced from: CubitCoordinateSystem::~CubitCoordinateSystem() in CubitCoordinateSystem.cpp.o ... Is CUBIT now required? Thx...John Cary PS - looking at geom/CMakeLists.txt, I see that I needed to add -DCGM_OCC:BOOL=ON to pick up OCC/OCE, but that did not help the build.....
