- (www.cmake.org)
-
- 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`
