请问一下，如何只修改内置target:on_build的runv()所传参数而不修改其他地方呢?

是这样的，我搞了个用于构建APE格式程序的xmake模板

最开始的编写和测试是在kde neon下进行的, 没有问题

但我试图在mingw(确切来说是git-bash)下进行测试时发现无法执行，报error: cannot runv(cosmocc -c -std=c11 -Iinclude -o build\.objs\main.com\unknown\unknown\release\src\main.c.o src\main.c), No such file or directory
使用xmake -vD的命令行输出如下

我个人的想法是修改内置的on_build的runv所传参数，但是我不清楚具体应该如何改动（并且我希望能够只在host为windows的情况下进行改动)

（注：cosmocc/bin/cosmocc是bash script，我试着直接跑 os.run("cosmocc --version")是跑不通的但os.run("sh cosmocc --version")是可以的）

（注：cosmocc/bin/cosmocc是bash script，我试着直接跑 os.run("cosmocc --version")是跑不通的但os.run("sh cosmocc --version")是可以的）

os.runv("cosmocc", {"--version"}, {shell = true})

[PumpkinXD]

此外请问一下内置的target:on_build也可以这样只替换os.runv么
我想内置的target:on_build只需要将os.runv替换成os.runv("cosmocc", <args>, {shell = true})的形式而其他地方不进行改动即可而非重写整个on_build

[waruqi]

不能

[PumpkinXD]

那么on_build_files或者on_build_file可以做到这样的修改粒度么?

也就是只修改编译文件的runv(prog,args...)而不修改其他的逻辑

如果可以的话我应该是选on_build_files还是on_build_file呢？

[waruqi]

on_build_file/on_buildcmd_file 你可以自己编译，参考其他 rule 。。lex yacc protobuf
