Bug: Error building with CMake and SDL3 #413

Closed m1maker closed 1 month ago

m1maker commented 1 month ago

Hello. I'm trying to build TTF with SDL3 and CMake and getting these errors. My CMakeLists

ExternalProject_Add(SDL3
    PREFIX "${CMAKE_BINARY_DIR}/external"
    GIT_REPOSITORY    "https://github.com/libsdl-org/SDL"
    GIT_TAG           "6771a6020da5052e22930c36cb1070a4c048ba3c"
    CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${CMAKE_BINARY_DIR}/external/installed -DSDL_STATIC=ON -DMSVC_RUNTIME_LIBRARY=MultiThreaded -DFORCE_STATIC_VCRT=ON
    )

    ExternalProject_Add(TTF
    PREFIX "${CMAKE_BINARY_DIR}/external"
    GIT_REPOSITORY    "https://github.com/libsdl-org/SDL_ttf"
    GIT_TAG           "5986e158279dbb0fe6de70e841c16bc1e9702d9f"
    CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${CMAKE_BINARY_DIR}/external/installed -DSDL_STATIC=ON -DMSVC_RUNTIME_LIBRARY=MultiThreaded -DFORCE_STATIC_VCRT=ON
    )

Just with SDL3, project is building good, but with TTF I getting strange build errors:

Make sure you're using latest SDL3 and SDL3_ttf. From your logs it appears they are incompatible.

I updated Git tag for SDL3 project, but no changes.

ExternalProject is for handling external projects that you only want to make available. Your code cannot depend on them, and these projects can also not depend on each other.

If you want to build your application in the same project, and link to it using SDL3::SDL3, you need to use the functions provided by FetchContent instead.

Having said that, after adding DEPENDS SDL3 to the arguments of the second ExternalProject_Add, I got it working on Linux. (I also added GIT_SHALLOW TRUE for faster cloning)

Also, verify the CMAKE_ARGS: -DSDL_SHARED and -DSDL_STATIC are SDL3-only options, not used by SDL_ttf. Use DBUILD_SHARED_LIBS=... for the satellite libraries.

Also, -DFORCE_STATIC_VCRT is not used by any SDL library.

Also, MSVC_RUNTIME_LIBRARY is not a CMake variable. You probably meant CMAKE_MSVC_RUNTIME_LIBRARY

But as I said before, you probably want to use FetchContent instead.
