utils.symbols.export_all/list 能不能导出C++符号?

[RPG3D]

Xmake 版本

2.9.8

操作系统版本和架构

windows 11 x64, msvc 14.43

描述问题

#2121
https://github.com/xmake-io/xmake/tree/dev/tests/projects/c/shared_library_export_list
上述示例中,无论是link foo还是foo2都无法link add sub函数
是不是Windows必须dllexport才行

期待的结果

添加utils.symbols.export_all后没有标记dllexport的c++符号可以被其他模块link

工程配置

#pragma once

#ifdef __cplusplus
//extern "C" {
#endif

int add(int a, int b);

#ifdef __cplusplus
//}
#endif

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

target("foo")
    set_kind("shared")
    add_files("src/foo.c")
    add_rules("utils.symbols.export_list", {symbols = {
        "add",
        "sub"}})

target("foo2")
    set_kind("shared")
    add_files("src/foo.c")
    add_files("src/foo.export.txt")
    add_rules("utils.symbols.export_list")

target("test")
    set_kind("binary")
    add_deps("foo")
    add_files("src/main.c")
