xmake will automatically detect the compiler installed by Keil/MDK, related issues #1753.

Compile with armcc

$ xmake f -p cross -a cortex-m3 --toolchain=armcc -c
$ xmake

Compile with armclang

$ xmake f -p cross -a cortex-m3 --toolchain=armclang -c
$ xmake

Executable program

target("hello")
     add_deps("foo")
     add_rules("mdk.console")
     add_files("src/*.c", "src/*.s")
     add_includedirs("src/lib/cmsis")
     set_runtimes("microlib")

It should be noted that when some mdk programs all use the microlib library to run, it requires the compiler to add the __MICROLIB macro definition, and the linker to add various configurations such as --library_type=microlib.

We can set directly to the microlib runtime library through set_runtimes("microlib"), and all relevant options can be set automatically.

Static library program

add_rules("mode.debug", "mode.release")

target("foo")
     add_rules("mdk.static")
     add_files("src/foo/*.c")
     set_runtimes("microlib")
