dlfcn-win32 Build status

dlfcn-win32 is an implementation of dlfcn for Windows.

dlfcn is a set of functions that allows runtime dynamic library loading. It is standardized in the POSIX. Windows also provide similar routines, but not in a POSIX-compatible way. This library attempts to implement a wrapper around the Windows functions to make programs written for POSIX that use dlfcn work in Windows without any modifications.

It follows the standard as described here:

Using This Library

Using CMake

Once the library has been installed, add to your project CMakeLists.txt :

...
find_package(dlfcn-win32 REQUIRED)
...
target_link_libraries(<target> dlfcn-win32::dl)
...

If you want to use this library in a cross-platform project, a convenient way to proceed is to define the CMake variable CMAKE_DL_LIBS (that is normally empty on Windows) and then use it for linking:

...
if (WIN32)
  find_package(dlfcn-win32 REQUIRED)
  set(CMAKE_DL_LIBS dlfcn-win32::dl)
endif ()  
...
target_link_libraries(<target> ${CMAKE_DL_LIBS})
...

When cross-compiling you might want to set CMAKE_CROSSCOMPILING_EMULATOR to the path of wine to run tests.
