How to build Box2D on Windows with mingw?

[gay-chicken]

Hi, I'm trying to build Box2D on Windows using MinGW and CMake. The build process completes smoothly without any errors.

However, when running the application, it prompts that the Box2D dynamic library is missing. I'm certain the build process went well with no errors reported.

In the target output folder, no Box2D dynamic library was generated.

I found similar issues online, and the responses suggested there might be format differences between dynamic libraries generated by MinGW and MSVC.

This has left me confused because even when I tried building with MSVC, the Box2D dynamic library still wasn't generated.

Here’s how I included Box2D in my project:

......
set(BOX2D_DIR ${SUBMODULE_DIR}/box2d)

.....
add_subdirectory(${BOX2D_DIR})

......
target_link_libraries(${PROJECT_NAME} PRIVATE
    box2d
    pthread
)

This sounds like a CMake question. I'm using MinGW but I'm also fetching and compiling with CMake, but if you already have it compiled I believe you need to do a find_library, then add_library with STATIC. Here's an example with Raylib:

find_library(PATH_RAYLIB raylib PATHS "${LOCAL_RAYLIB}" REQUIRED NO_CMAKE_FIND_ROOT_PATH)

add_library(raylib STATIC IMPORTED)
set_target_properties(raylib PROPERTIES IMPORTED_LOCATION "${PATH_RAYLIB}")

target_include_directories(${PROJECT_NAME} PRIVATE "${LOCAL_RAYLIB}")
