使用mingw toolchain无法检测 HAVE_INTPTR_T #4173

da-liii · 2023-09-06T14:27:49Z

Xmake 版本

dev and 2.8.2

操作系统版本和架构

Windows 11

描述问题

xmake config -p mingw

无法检测

configvar_check_cxxtypes("HAVE_INTPTR_T", "intptr_t", {includes = {"memory"}})

在手动将mingw相关路径加入之后，可以检测到 HAVE_INTPTR_T，比如 https://github.com/XmacsLabs/lolly/blob/main/bin/config_mingw

期待的结果

HAVE_INTPTR_T能够被检测到

工程配置

附加信息和错误日志

xmake config的关键信息

这只是你的编译错误，要看 xmake f -vD; xmake -vD 的 check error info 。。贴下

Error message (related to the lolly warehouse)

This is just your compilation error, it depends on the check error info of xmake f -vD; xmake -vD. . posted

这个不太好搞，因为你用了 add_requires + add_toolchains + mingw 去绑定的工具链，这个是 target 粒度的，尽管是对所有 target 生效，但毕竟不是全局的。。

而你用的 configvar_check_cxxtypes 是全局接口，跟 target 没有关系，因此它无法获取到 add_toolchains 的工具链信息，只能从全局平台层获取工具链，而全局平台工具链，如果系统没有 mingw，也没 xmake f -p mingw --mingw=/xxx 指定路径，是获取不到的，因此检测会失败。

而 configvar_check_cxxtypes 内部实现走的 option，这个阶段不太可能取到 add_toolschains 的信息，即使后期想支持也不好实现

如果想要在自动绑定 toolchains 的前提下，也能实现自动检测，得用 target 的检测接口才行。。

add_requires("mingw-w64 8.1.0")
set_toolchains("mingw@mingw-w64")

target("test")
    on_config(function (target)
        if target:has_cxxtypes("intptr_t", {includes = "memory"}) then
            target:set("configvar", "HAVE_INTPTR_T", 1)
        end
    end)

其他的检测接口类似，target 层的检测接口，跟 add_toolchains 工具链绑定是同步的，而且不同 target 可以绑定不同的 toolchains ，也不会干扰检测。。

具体见 #3522
https://xmake.io/#/zh-cn/manual/target_instance?id=targethas_cxxtypes

如果觉得每个 target 都这么配置比较繁琐，可以单独搞个 check.lua 的模块，配置所有检测后，统一处理。。

独立模块可以像 cmake 那样，单独搞个 xmake 目录维护所有配置脚本，然后用 add_moduledirs + import 引入

https://xmake.io/#/zh-cn/manual/global_interfaces?id=add_moduledirs

- projectdiur
- xmake
  - check.lua
- src
- xmake.lua

add_moduledirs("xmake")

-- 全局配置，所有 target 生效
on_config(function (target)
    import("check")
    check(target)
end)

target("test1")
target("test2")

check.lua

function main(target)
    -- check cxxtypes
    -- check includes
    -- check functions ...
end

感谢，已成功配置：XmacsLabs/lolly#137

在target进行的检测可以缓存吗？on_config事件每次编译前都会触发，导致重复检测

Issues-translate-bot · 2023-09-10T15:32:11Z

Bot detected the issue body's language is not English, translate it automatically.

Can detection performed at target be cached? The on_config event will be triggered before each compilation, resulting in repeated detection.

没有， on_config 每次配置都会被执行，不过 dev 我刚加了个 recheck 状态，你可以根据这个来判断是否需要检测

on_config(target, opt)
    if opt.recheck and target:has_cfuncs(...) then
    end
 end

No, on_config will be executed every time the configuration is configured, but I just added a recheck status to dev. You can use this to determine whether detection is needed.

on_config(target, opt)
     if opt.recheck and target:has_cfuncs(...) then
    end
 end
