交叉编译器获取不到check_sizeof大小

[ririyeye]

Xmake 版本

v2.8.5+master

操作系统版本和架构

ubuntu22 gcc-linaro-5.4.1-2017.05-x86_64_arm-linux-gnueabihf

描述问题

交叉编译器无法获取到target:check_sizeof数据
配置阶段的编译器检查编译文件时链接了后级的库 导致链接失败 然后target:check_sizeof执行失败

期待的结果

aarch64应该是8

工程配置

target("cmd_dbg")
    on_config(function (target)
        print("sizeof(long) = %s", target:check_sizeof("long"))
        print("sizeof(string) = %s", target:check_sizeof("std::string", {includes = "string"}))
        if target:check_sizeof("long") == 8 then
            target:add("defines", "LONG64")
        end
    end)
    set_kind("binary")
    add_files("cmd_dbg.cpp")
    set_languages("c++11")
    add_deps("ar8030_client")

看下这两个库在哪配置的，库在哪个路径下

Check where these two libraries are configured and which path they are under.

[ririyeye]

这两个库是同个项目下编译生成的 没有进到编译阶段 所以这两个库还没有开始编译

These two libraries were compiled and generated under the same project and have not entered the compilation stage, so the compilation of these two libraries has not started yet.

[waruqi]

这得需要改下内部实现，估计得等几天，你可以用描述域 check_sizeof 接口，那个是不继承 target 配置的

This requires changing the internal implementation, which may take a few days.

再试试 xmake update -s github:xmake-io/xmake#check

Try xmake update -s github:xmake-io/xmake#check again

可以了
