Build Configuration

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

::: tip NOTE You can use short or long command options, 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 the 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 other Android toolchains, you can use the --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 the bin directory of toolchains.

::: tip NOTE Please try to set the --arch= option if it fails to check the 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 architecture alone. Therefore, in version 2.6.5, we have added a new parameter to distinguish between simulator targets and device 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 building Mac Catalyst programs.

$ xmake f --appledev=catalyst

Windows

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

MinGW

In addition to supporting Msys2/MingW and MingW for macOS/Linux, xmake also supports the llvm-mingw toolchain, which can switch to the arm/arm64 architecture for compilation.

$ 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 (the emcc toolchain is used internally). Before switching to 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 the Qt SDK. If the versions do 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 HarmonyOS 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 to simplify operation.

For example:

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

Now, we configure and build the project for Android again.

$ xmake f -p android
$ xmake

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

Clean Configuration

We can clean all cached configuration and re-configure the 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 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
