cannot build shared memory with MSVC module #5383

Xmake 版本

操作系统版本和架构

Windows 22H2

描述问题

在使用 MSVC modules 构建动态库时, 会报链接错误. 如下代码设置set_kind("binary")便可编译通过; 但编译到.dll时会报错:

error: main.cpp.obj : error LNK2019: 无法解析的外部符号 "public: static int const std::_General_precision_tables_2::_Max_P" (?_Max_P@?$_General_precision_tables_2@N@std@@2HB)，函数 "struct std::to_chars_result cdecl std::_Floating_to_chars_general_precision(char ,char const,double,int)" (??$_Floating_to_chars_general_precision@N@std@@YA?AUto_chars_result@0@PEADQEADNH@Z) 中引用了该符号 main.cpp.obj : error LNK2019: 无法解析的外部符号 "public: static int const std::_General_precision_tables_2::_Max_P" (?_Max_P@?$_General_precision_tables_2@M@std@@2HB)，函数 "struct std::to_chars_result cdecl std::_Floating_to_chars_general_precision(char ,char const,float,int)" (??$_Floating_to_chars_general_precision@M@std@@YA?AUto_chars_result@0@PEADQEADMH@Z) 中引用了该符号 build\windows\x64\release\module.dll : fatal error LNK1120: 2 个无法解析的外部命令

在 microsoft/STL#4343 中提到这个错误是由于未链接std.obj导致的, 查看-vD后可以发现,set_kind("binary") 链接了std.obj而set_kind("shared")确实未链接

期待的结果

编译通过

工程配置

xmake.lua

target("module")
    set_languages("c++23")
    set_policy("build.c++.modules", true)
    set_kind("shared")
    add_files("src/*.cpp")

main.cpp

import std;

int main() 
{
    std::println("hello world, num {}", 3.3);
    return 0;
}

I added target:is_shared() , it will work. @Arthapz
