Hello,
I’m trying to compile VTK-9.5.0 and use the resulting build as a library for compiling my own C++ code targeting WebAssembly.
During the VTK build process, I followed the instructions from the official guide (Building using emscripten for WebAssembly - VTK documentation) and enabled the option -DVTK_WEBASSEMBLY_THREADS:BOOL=ON.
When compiling my C++ project with this VTK build, I added the following flags in my CMakeLists.txt:
-pthread and -sPROXY_TO_PTHREAD=1
However, I encountered the following error:
–shared-memory is disallowed by vtkSMPThreadPool.cxx.o because it was not compiled with ‘atomics’ or ‘bulk-memory’ features.
Is there a specific flag or configuration I may have missed when building VTK to support threads in WASM?
Any help would be greatly appreciated!
