Xmake Swig 模块示例

2.5.8 版本支持构建 Swig 模块，我们提供了 swig.c 和 swig.cpp 规则，分别对应支持生成 c/c++ 模块接口代码，配合 xmake 的包管理系统实现完全自动化的模块和依赖包整合。

add_rules("mode.release", "mode.debug")
-- make sure you config to an enviroment with jni.h
-- for example: xmake f -c -p android

target("example")
    set_kind('shared')
    -- set moduletype to java
    add_rules("swig.c", {moduletype = "java"})
    -- test jar build
    -- add_rules("swig.c", {moduletype = "java" , buildjar = true})
    -- use swigflags to provider package name and output path of java files
    add_files("src/example.i", {swigflags = {
        "-package",
        "com.example",
        "-outdir",
        "build/java/com/example/"
    }})
    add_files("src/example.c")
    add_includedirs("src")
    before_build(function()
        -- ensure output path exists before running swig
        os.mkdir("build/java/com/example/")
    end)

我们也可以配置

add_rules("swig.c", {moduletype = "java", buildjar = true})

去同时构建 jar 包，方便直接使用。
