set_strip("debug") 似乎未生效

[ivanallen]

手动 strip -S 后，发现和 xmake 生成的文件大小不一致。

查了下源码，似乎 gnu strip 默认都走 strip -s ?

[waruqi]

只有开了 mode.releasedbg 模式，才会通过 strip -s 走独立的 symbols 符号抽取，而通常使用的 mode.release 不走 strip -s 独立命令 ，直接走 clang++/g++ -s 链接的时候，就已经 strip all 了。。

[waruqi]

是否生效，自己 -v 检查下 link args，可以贴出来，否则我咋知道 怎么回事。。

另外，配置 mode.release mode.releasedbg 不同的编译模式，都会有不同的行为，要看你配置了什么，切什么模式，没 logs 也没 配置。。我无法提供更多建议

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

if is_mode("releasedbg") then
    set_strip("debug")
end

target("add")
    set_kind("static")
    add_files("src/add.cpp")

target("bar")
    set_kind("binary")
    add_files("src/main.cpp")
    add_deps("add")

[waruqi]

然后呢，什么问题呢？

[ivanallen]

我在 releasedbg 下配置了 set_strip("debug"), 理论上应该是使用 strip -S 而不是 strip -s 吧？

[waruqi]

再试试，xmake update -s dev

[ivanallen]

可以了，现在没问题了。
