[MaxwellGengYF]

Xmake 版本

v2.9.5+dev.21e4c2a3a

操作系统版本和架构

Windows

描述问题

同项目使用 cross compile 导致 can not find program ar

期待的结果

正常编译。

工程配置

target("llvm_target")
set_languages("cxx20")
set_toolchains("llvm")
on_load(function(target)
    target:set("kind", "static")
end)
add_files("dummy.cpp")
target_end()

target("clang_cl_target")
set_languages("cxx20")
on_load(function(target)
    target:set("kind", "static")
end)
add_files("dummy.cpp")
target_end()

xmake f -m debug --toolchain=clang_cl -c
xmake
xmake f -m release --toolchain=clang_cl -c
xmake
xmake f -m debug --toolchain=clang_cl -c
xmake
...

附加信息和错误日志

试下，应该可以了，这个跟 cache 没啥关系，是 clang-cl toolchain 的问题。。

因为 msvc/clang-cl 都是用的 link.exe ，但是探测 find_link 需要调用 cl/clang-cl 去尝试编译+ link

切到 clang-cl toolchain 后，envs 被加载为 clang-cl的环境，cl.exe 不在 PATH 里，所以之前 find_link 固定用 cl.exe 去探测，就会出这个问题，导致 link.exe 没找到。

Try it, it should work. This has nothing to do with the cache, it is a problem with the clang-cl toolchain. .

Because msvc/clang-cl all use link.exe, but to detect find_link you need to call cl/clang-cl to try to compile + link

After switching to the clang-cl toolchain, envs is loaded as the clang-cl environment, and cl.exe is not in the PATH. Therefore, before find_link was fixed to use cl.exe to detect, this problem will occur, causing link.exe not to be found.
