How do I build sdl2 with meson?

Using this meson file,

project('mytest', 'c')
cc = meson.get_compiler('c')

deps = []
deps += dependency('sdl2',
  required: true,
  static: true,
  method: 'pkg-config')


executable('demo', 
           'src/main.c', 
           dependencies : deps,
           gui_app: true)

I get the following error

 error LNK2019: unresolved external symbol WinMain referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ)

This seems to be related to the SDLmain.lib (I'm sure it exist).
How would you force the linker to link to this library?

I'm on windows 10, using the MSVC compiler.

Solution

  • You're building a gui app, not a terminal app. With MSVC, when you set gui_app : true (or in more recent versions of meson win_subsystem : 'windows') you don't provide a main function, you provide WinMain function instead.

    See the MSDN documentation

    Under the hood this option is passing /SUBSYSTEM:WINDOWS to the compiler
