Before I go, a few questions about symbols visibility... Does the compiler flags -fvisibility=hidden -fvisibility-inlines-hidden have any effect? Does the __attribute__(visibility(...)) have any effect?
I am wondering because at link time I get a list of undefined symbols, and I verified with llvm-nm that the symbols are present in the library, such as : T _ZN5physx26PxSceneLimitsGeneratedInfoC1Ev Yet Emscripted complains it can't find it : warning: unresolved symbol: _ZN5physx26PxSceneLimitsGeneratedInfoC1Ev I also verified I properly link with the library : DEBUG root: linking: ['CMakeFiles/main_webgl.dir/main.cpp.o', '../lib/libapplication.a', '../lib/libengine.a', '../lib/libfoundation.a', '../lib/li bgame.a', '../lib/libphysx_cct.a', '../lib/libgl_render_device.a', 'D:/dev/project/lib/physx-3.3.3-webgl-r1/Lib/libPhysX3CHECKED.a', 'D:/dev/project /lib/physx-3.3.3-webgl-r1/Lib/libPhysX3CommonCHECKED.a', 'D:/dev/project/lib/physx-3.3.3-webgl-r1/Lib/libPhysX3ExtensionsCHECKED.a', 'D:/dev/project /lib/physx-3.3.3-webgl-r1/Lib/libPhysX3VehicleCHECKED.a', 'D:/dev/project/lib/physx-3.3.3-webgl-r1/Lib/libPhysXVisualDebuggerSDKCHECKED.a', 'D:/dev/s tingray/lib/physx-3.3.3-webgl-r1/Lib/libPxTaskCHECKED.a', 'D:/dev/project/lib/physx-3.3.3-webgl-r1/Lib/libLowLevelCHECKED.a', 'D:/dev/project/lib/ph ysx-3.3.3-webgl-r1/Lib/libLowLevelClothCHECKED.a', 'D:/dev/project/lib/physx-3.3.3-webgl-r1/Lib/libSceneQueryCHECKED.a', 'D:/dev/project/lib/physx-3 .3.3-webgl-r1/Lib/libSimulationControllerCHECKED.a', 'D:/dev/project/lib/physx-3.3.3-webgl-r1/Lib/libPvdRuntimeCHECKED.a', 'D:/dev/project/lib/physx -3.3.3-webgl-r1/Lib/libPhysXProfileSDKCHECKED.a', '../lib/liblua.a', 'D:/dev/project/lib/emscripten-1.34.6-r0/.emscripten_cache\\libcxxabi.bc', 'D:/d ev/project/lib/emscripten-1.34.6-r0/.emscripten_cache\\gl.bc', 'D:/dev/project/lib/emscripten-1.34.6-r0/.emscripten_cache\\libc-mt.bc', 'D:/dev/stin gray/lib/emscripten-1.34.6-r0/.emscripten_cache\\pthreads.bc', 'D:/dev/project/lib/emscripten-1.34.6-r0/.emscripten_cache\\dlmalloc_threadsafe.bc', ' D:/dev/project/lib/emscripten-1.34.6-r0/.emscripten_cache\\libcxx_noexcept.a'] ...

I don't see any specific information at link time with EMCC_DEBUG=1 regarding this symbol. Doesn't look like it's getting discarded (or if it is, there's no message about it). What could be wrong? We are using the CMake toolchain file provided with Emscripten to build everything. Why is Emscripten not able to find these symbols, even thought we clearly see them in the library?
