Compile Command: cmake -G Ninja -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} -DVTK_DIR=/work/vtk-v9.1.0-wasm-build /work/examples/ReadOBJ/ error:

error "Including files directly from the emscripten source tree is not supported. Please use the cache/sysroot/include directory".

` If don't import these two header files, there's no problem why?

[sbc100]

Somebody (most likely your CMAKE_TOOLCHAIN_FILE) is incorrectly adding the internal emscripten include directory to the include path?

What is CMAKE_TOOLCHAIN_FILE and where is it coming from? is the to official emscripten cmake toolchain file?

What is the full failing command line? (The emcc/em++ command that caused that error?)

[sbc100]

The headers in question should be includable just fine, but from emscripten/cache/sysroot/include (where they live in the sysroot) not from emscripten/system/include (where they live in the source tree)

[sheonny]

cmake -G Ninja -DCMAKE_TOOLCHAIN_FILE=/emsdk/upstream/emscripten/cmake/Modules /Platform/Emscripten.cmake -DVTK_DIR=/work/vtk-v9.1.0-wasm-build /work/examples/ReadOBJ/ emscripten cmake toolchain file is /emsdk/upstream/emscripten/cmake/Modules /Platform/Emscripten.cmake If the header is not imported, this error will not occur, but I need it

[sbc100]

You can and should include the header but you need to fix your include path. Can you share the full failing command line ? (that should be part of the output of the failing ninja command, If you are not sure you can just share the full output of the build that fails)

[sheonny]

command line： cmake -G Ninja -DCMAKE_TOOLCHAIN_FILE=/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake -DVTK_DIR=/work/vtk-v9.1.0-wasm-build /work/examples/ReadOBJ/ output： cmake --build . output: options: list(APPEND emscripten_options "--bind" "-g3" "SHELL:-s EXPORT_NAME=vtkApp" "SHELL:-s ALLOW_MEMORY_GROWTH=1" "SHELL:-s ASSERTIONS=1" "SHELL:-s DEMANGLE_SUPPORT=1" "SHELL:-s EMULATE_FUNCTION_POINTER_CASTS=0" "SHELL:-s ERROR_ON_UNDEFINED_SYMBOLS=0" "SHELL:-s MODULARIZE=1" "SHELL:-s USE_PTHREADS=0" "SHELL:-s WASM=1" "SHELL:-s EXPORTED_FUNCTIONS=\"['_main', '_stop']\"" "SHELL:-s EXTRA_EXPORTED_RUNTIME_METHODS=\"['ccall', 'cwrap']\"" "SHELL:-s ENVIRONMENT=web" "SHELL:--preload-file ./ferrari-f1-race-car.obj" ) remarks: Successfully build in version 1.39.10 of emscripten!!!

[sbc100]

Can you copy and paste the full terminal output, rather than attaching an image? ( Its much less usefull as an imagine because it can't be copied/pasted/searched. Also the image cuts of the actual command line so I can't actually see where the bad include is being added).

There emcc command which is cut off in your image will likely contain -I/emsdk/upstream/emscripten/system/include. To fix this build error you will need to find out where that is being added and prevent it or remove it.

So you can see the problem in the em++ command. It includes -isystem /emsdk/upstream/emscripten/system/include which is incorrect. Its not clear to me how that is getting added, but it must be coming from cmake somewhere. You need to track that down and remove it somehow.

Perhaps grep all your sources for "system/include"?

[sbc100]

Looking at the VTK software you are trying to build it looks like they have a recent change to CMake/patches/99/FindOpenGL.cmake which tries to fix this issue: https://gitlab.kitware.com/vtk/vtk/-/commit/f199bdb19fdb20281959f175549e6cc289b95eeb

Looks like you maybe need to get that patch.

[jspanchu]

@sheonny, we've fixed this on VTK side recently. You've two options:

1. Clone VTK from source and build the master branch with emsdk. Instructions here
2. Use pre-built kitware/vtk-wasm docker image.
