macOS CLion xmake生成的cmakelists编译报错

[wumo]

Xmake 版本

2.7.3

操作系统版本和架构

macOS Ventura

描述问题

xmake生成范例项目代码，生成cmakelists.txt然后编译报错

期待的结果

正常编译运行

工程配置

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

target("lumos")
    set_kind("shared")
    add_files("src/interface.cpp")

target("lumos_demo")
    set_kind("binary")
    add_deps("lumos")
    add_files("src/main.cpp")

附加信息和错误日志

感觉跟 xmake 关系不大，xmake 已经正常生成了动态库 target

add_library(lumos SHARED "")

然后 cmake 添加了 -dynamiclib flag 来作为动态库去 link

但是被 clang 给忽略了，然后作为可执行程序去 link 了，所以报错。。

clang: warning: argument unused during compilation: '-dynamiclib' [-Wunused-command-line-argument]

我手动添加 -shared flag 以及 xmake 直接编译link 传的 -shared 都能正常过掉的。。

但是 cmake 里面 macosx 上编译动态库，传入的是 -dynamiclib 而不是 -shared，按理 -dynamiclib 也是应该等价可用的，但是现在被clang 忽略了。

反正要么是 cmake 的问题，要么是 clang 的问题，跟 xmake 好像没啥关系。。

@waruqi 我发现只要注释掉

target_link_options(lumos PRIVATE
        -target
        -isysroot
        -stdlib=libc++
)

就可以成功链接

@waruqi
又试了几次，-target会导致 未定义符号_main，而-isysroot会导致找不到-lz

[waruqi]

应该可以了，更新到 dev 试试

xmake update -s dev

[wumo]

@waruqi ok了
