Added sdl2_bundled and sdl2_static_link features #33



Copy link

VictorKoenders commented Dec 14, 2018

SDL2 has a nice feature called "bundled":

Since 0.31, this crate supports a feature named "bundled" which downloads SDL2 from source, compiles it and links it automatically. While this should work for any architecture, you will need a C compiler (like gcc, clang, or MS's own compiler) to use this feature properly.

In addition, for my games I also link things statically. SDL2 has a feature for that called "static-link":

Static linking with MinGW
If you want to use the static-link feature with the windows-gnu toolchain, then you will also need the following libraries:

These files are not currently included with the windows-gnu toolchain, but can be downloaded here. For the x86_64 toolchain, you want the x86_64-win32-seh package, and for i686 you want the i686-win32-dwarf one.

You will find the aforementioned libraries under mingw64/x86_64-w64-mingw32/lib/ (for x86_64) or mingw32/i686-w64-mingw32/lib/ (for i686). Copy them to your toolchain's lib directory (the same one you copied the SDL .a files to).
Static linking with MSVC
The MSVC development libraries provided by don't include a static library. This means that if you want to use the static-link feature with the windows-msvc toolchain, you have to either

build an SDL2 static library yourself and copy it to your toolchain's lib directory; or
also enable the bundled feature, which will build a static library for you.

Cool! I was avoiding turning these on by default, as it sounds like they have their own set of tradeoffs (the less CMake in my life, the better 😅), but I see absolutely no harm in making the features available if people want them.
