Hi, all
I have compiled VTK-9.0.20210224 as lib and it worked well with my project. Now the question is , how can I use TBB or OpenMP for multithreading in web page ? I have tested on win 10 + VTK+TBB it is all OK.
dir list is :
/work/vtk/build
/work/wasmtbb/
tbb can be built in /work/wasmtbb/build/linux_wasm32_emscripten_emscripten_wasm32_release/libtbb.a
I tried this :
cmake
-G Ninja
-DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE}
-DBUILD_SHARED_LIBS:BOOL=OFF
-DCMAKE_BUILD_TYPE:STRING=Release
-DVTK_ENABLE_LOGGING:BOOL=OFF
-DVTK_ENABLE_WRAPPING:BOOL=OFF
-DVTK_LEGACY_REMOVE:BOOL=ON
-DVTK_OPENGL_USE_GLES:BOOL=ON
-DVTK_USE_SDL2:BOOL=ON
-DVTK_NO_PLATFORM_SOCKETS:BOOL=ON
-DVTK_MODULE_ENABLE_VTK_hdf5:STRING=NO
-DVTK_SMP_IMPLEMENTATION_TYPE:STRING=TBB
-DTBB_INCLUDE_DIR:STRING=/work/wasmtbb/include
-DTBB_LIBRARY_RELEASE:STRING=/work/wasmtbb/build/linux_wasm32_emscripten_emscripten_wasm32_release/libtbb.a
…
cmake worked but errors appearted during make like this :
In file included from …/Common/Core/SMP/TBB/vtkSMPTools.cxx:16:
In file included from …/Common/Core/vtkSMPTools.h:32:
In file included from Common/Core/vtkSMPThreadLocal.h:81:

PS:
I followed this link boilerplate/install.md at master · hpcwasm/boilerplate · GitHub
and I have a question , does TBB need boost to work together ?
Any help would be greatly appreciated !
Thanks !
