CMake

================================================================================

|
SDL's build system was traditionally based on autotools. Over time, this
|
|
approach has suffered from several issues across the different supported
|
|
platforms.
|
|
To solve these problems, a new build system based on CMake is under development.
|
|
It works in parallel to the legacy system, so users can experiment with it
|
|
without complication.
|
|
While still experimental, the build system should be usable on the following
|
|
platforms:
|
|
|
|
* FreeBSD
|
|
* Linux
|
|
* VS.NET 2010
|
|
* MinGW and Msys
|
|
* macOS, iOS, and tvOS, with support for XCode
|
|
|
|

Usage
|
|
================================================================================
|
|
|
|
Assuming the source for SDL is located at ~/sdl
|
|
|
|
cd ~
|
|
mkdir build
|
|
cd build
|
|
cmake ../sdl
|
|
|
|
This will build the static and dynamic versions of SDL in the ~/build directory.
|
|
|
|
|
|

Usage, iOS/tvOS

================================================================================

CMake 3.14+ natively includes support for iOS and tvOS. SDL binaries may be built
|
|
using Xcode or Make, possibly among other build-systems.
|
|
|
|
When using a recent version of CMake (3.14+), it should be possible to:
|
|
|
|
- build SDL for iOS, both static and dynamic
|
|
- build SDL test apps (as iOS/tvOS .app bundles)
|
|
- generate a working SDL_config.h for iOS (using SDL_config.h.cmake as a basis)
|
|
|
|
To use, set the following CMake variables when running CMake's configuration stage:
|
|
|
|
- `CMAKE_SYSTEM_NAME=<OS>` (either `iOS` or `tvOS`)
|
|
- `CMAKE_OSX_SYSROOT=<SDK>` (examples: `iphoneos`, `iphonesimulator`, `iphoneos12.4`, `/full/path/to/iPhoneOS.sdk`,
|
|
`appletvos`, `appletvsimulator`, `appletvos12.4`, `/full/path/to/AppleTVOS.sdk`, etc.)
|
|
- `CMAKE_OSX_ARCHITECTURES=<semicolon-separated list of CPU architectures>` (example: "arm64;armv7s;x86_64")
|
|
|
|
|
|
### Examples (for iOS/tvOS):
|
|
|
|
- for iOS-Simulator, using the latest, installed SDK:
|
|
|
|
`cmake ~/sdl -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64`
|
|
|
|
- for iOS-Device, using the latest, installed SDK, 64-bit only
|
|
|
|
`cmake ~/sdl -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES=arm64`
|
|
|
|
- for iOS-Device, using the latest, installed SDK, mixed 32/64 bit
|
|
|
|
`cmake ~/sdl -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES="arm64;armv7s"`
|
|
|
|
- for iOS-Device, using a specific SDK revision (iOS 12.4, in this example):
|
|
|
|
`cmake ~/sdl -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos12.4 -DCMAKE_OSX_ARCHITECTURES=arm64`
|
|
|
|
- for iOS-Simulator, using the latest, installed SDK, and building SDL test apps (as .app bundles):
|
|
|
|
`cmake ~/sdl -DSDL_TEST=1 -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64`
|
|
|
|
- for tvOS-Simulator, using the latest, installed SDK:
|
|
|
|
`cmake ~/sdl -DCMAKE_SYSTEM_NAME=tvOS -DCMAKE_OSX_SYSROOT=appletvsimulator -DCMAKE_OSX_ARCHITECTURES=x86_64`
|
|
|
|
- for tvOS-Device, using the latest, installed SDK:
|
|
|
|
`cmake ~/sdl -DCMAKE_SYSTEM_NAME=tvOS -DCMAKE_OSX_SYSROOT=appletvos -DCMAKE_OSX_ARCHITECTURES=arm64`
