Disable deprecations treated like errors?

[andreamancuso]

Hi,

I'm trying to compile https://github.com/maplibre/maplibre-native using emscripten. I'm trying to retain the existing CMakeLists.txt, though I have had to disable the /WX flag.

I am trying to figure out how to run emcmake but I ideally need help figuring out which flags I need to pass. Has anyone ever tried anything like it?

I ran emcmake cmake . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DMLN_WITH_CORE_ONLY=1 -DMLN_WITH_WERROR=OFF but then I've noticed that the .lib file generated as part of running cmake --build build does not contain WASM or LLVM output. How do I force it to use em++?

I also tried a different approach, I added add_subdirectory(${DEPS}/maplibre-native) to my CMakeLists.txt so now I am certain that em++ is being used.

Also:

target_link_libraries(reactDearImgui PRIVATE imgui::imgui implot::implot nlohmann_json::nlohmann_json $<IF:$<TARGET_EXISTS:libuv::uv_a>,libuv::uv_a,libuv::uv> JPEG::JPEG mbgl-core)

I am getting errors such as

C:/dev/react-imgui/packages/dear-imgui/cpp/deps/maplibre-native/vendor/mapbox-base/deps/variant/include\mapbox/variant.hpp:533:37: error: 'aligned_storage<12, 4>' is deprecated [-Werror,-Wdeprecated-declarations]

It seems deprecations are treated like errors?

It looks like aligned_storage was deprecated in C++23: https://en.cppreference.com/w/cpp/types/aligned_storage.

You can suppress the warning or you can update mapbox to avoid using it.

Sorry, I should have RTFM on this one.
