Build Configuration

Set compilation configuration before building project with command xmake f|config. If you want to known more options, please run: xmake f --help。

::: tip NOTE You can use short or long command option, for example:
xmake f or xmake config.
xmake f -p linux or xmake config --plat=linux. :::

Switch Platforms

Current Host

:::tip NOTE Xmake will detect the current host platform automatically and build project. :::

$ xmake

Linux

$ xmake f -p linux [-a i386|x86_64]
$ xmake

Android

$ xmake f -p android --ndk=~/files/android-ndk-r10e/ [-a armeabi-v7a|arm64-v8a]
$ xmake

If you want to set the other android toolchains, you can use --bin option.

For example:

$ xmake f -p android --ndk=~/files/android-ndk-r10e/ -a arm64-v8a --bin=~/files/android-ndk-r10e/toolchains/aarch64-linux-android-4.9/prebuilt/darwin-x86_64/bin

The --bin option is used to set bin directory of toolchains.

::: tip NOTE Please attempt to set --arch= option if it had failed to check compiler. :::

iPhoneOS

$ xmake f -p iphoneos [-a armv7|armv7s|arm64|i386|x86_64]
$ xmake

Since the emulator on the m1 device also supports the arm64 architecture, it is no longer possible to distinguish the emulator from the arch alone. Therefore, in version 2.6.5, we have added a new parameter to distinguish between emulator targets and emulator targets.

$ xmake f -p iphoneos --appledev=simulator
$ xmake f -p watchos --appledev=simulator
$ xmake f -p appletvos --appledev=simulator

Mac Catalyst

We can also specify to build Mac Catalyst programs.

$ xmake f --appledev=catalyst

Windows

$ xmake f -p windows [-a x86|x64]
$ xmake

MinGW

In addition to supporting Msys2/MingW, MingW for macOS/linux, xmake also supports the llvm-mingw tool chain, which can switch the arm/arm64 architecture to compile.

$ xmake f -p mingw --sdk=/usr/local/i386-mingw32-4.3.0/ [-a i386|x86_64|arm|arm64]
$ xmake

WASM (WebAssembly)

This platform is used to compile WebAssembly programs (emcc toolchain is used internally). Before switching this platform, we need to enter the Emscripten toolchain environment to ensure that emcc and other compilers are available.

$ xmake f -p wasm
$ xmake

Xmake also supports Qt for wasm compilation, you only need:

$ xmake f -p wasm [--qt=~/Qt]
$ xmake

The --qt parameter setting is optional, usually xmake can detect the sdk path of qt.

One thing to note is that there is a correspondence between the versions of Emscripten and Qt SDK. If the version does not match, there may be compatibility issues between Qt/Wasm.

Regarding the version correspondence, you can see: https://wiki.qt.io/Qt_for_WebAssembly

For more details, please see: https://github.com/xmake-io/xmake/issues/956

In addition to emscripten, there is a common wasi-sdk toolchain for building wasi-based programs, and we just need to switch between toolchains.

$ xmake f -p wasm --toolchain=wasi
$ xmake

Apple WatchOS

$ xmake f -p watchos [-a i386|armv7k]
$ xmake

HarmonyOS

Version 2.9.1 adds native toolchain compilation support for the Hongmeng OS platform:

$ xmake f -p harmony

xmake will automatically detect the default SDK path, but you can also specify the Harmony SDK path.

$ xmake f -p Harmony --sdk=/Users/ruki/Library/Huawei/Sdk/openharmony/10/native

Global Configuration

You can save to the global configuration for simplfying operation.

For example:

$ xmake g --ndk=~/files/android-ndk-r10e/

Now, we config and build project for android again.

$ xmake f -p android
$ xmake

::: tip NOTE You can use short or long command option, for example: xmake g or xmake global. :::

Clean Configuration

We can clean all cached configuration and re-configure project.

$ xmake f -c
$ xmake

or

$ xmake f -p iphoneos -c
$ xmake

Import and export configuration

After 2.5.5, we can also import and export the configured configuration set to facilitate rapid configuration migration.

Export configuration

$ xmake f --export=/tmp/config.txt
$ xmake f -m debug --xxx=y --export=/tmp/config.txt

Import configuration

$ xmake f --import=/tmp/config.txt
$ xmake f -m debug --xxx=y --import=/tmp/config.txt

Export configuration (with menu)

$ xmake f --menu --export=/tmp/config.txt
$ xmake f --menu -m debug --xxx=y --export=/tmp/config.txt

Import configuration (with menu)

$ xmake f --menu --import=/tmp/config.txt
$ xmake f --menu -m debug --xxx=y --import=/tmp/config.txt
