Xmake Version

xmake v2.9.2+20240525

Operating System Version and Architecture

Fedora 40 KDE x86_64

Describe Bug

If I just compile everything together, without making static library, it works fine. As soon as I put the C++20 module file into a static library target, I get the error

Expected Behavior

To compile?

Project Configuration

add_rules("mode.release", "mode.debug")
set_languages("c++23")

-- Without the static library target, no errors occur
target("x-lib")
    set_kind("static")
    add_files("cpp/Math/**.mpp")

target("x-app")
    set_kind("binary")
    add_files("cpp/*.cpp")
    add_deps("x-lib")

cpp/main.cpp

import Vector;

int main()
{
    // Testing my module!
    x::Vector2f v1{ 2.5f, 3.1f };
    v1.print();
}

cpp/Math/Vector.mpp

module;
#include <cmath>
#include <print>

export module Vector;

export namespace x
{

template <typename T>
struct Vector2D
{
    T x{}, y{};

    void print() const
    {
        std::println("Vector2: [{}, {}]", x, y);
    }
};

using Vector2f = Vector2D<float>;
using Vector2i = Vector2D<int>;

} // x

try use moduleonly instead of static

add_rules("mode.release", "mode.debug")
set_languages("c++23")

-- Without the static library target, no errors occur
target("x-lib")
    set_kind("moduleonly")
    add_files("cpp/Math/**.mpp")

Ok, for this minimal example project, it works. But for a bigger project that adds dependencies (libsdl, opengl, etc), everything compiles, but I got a lot of linker errors

$ xmake

Can C++20 modules be used to make a static library? I hope so Running xmake -vD adds this output:

Can C++20 modules be used to make a static library? I hope so

when only module files exsit, please use moduleonly. when both module/cpp or only cpp files exsit, please use static.

https://github.com/xmake-io/xmake/blob/master/tests/projects/c%2B%2B/static_library/xmake.lua

And I did not find add_requires in your xmake.lua

I've tried to make a minimal version of my project file, here it is the complete code

    set_optimize("none")
end

if is_mode("release") then
    set_symbols("hidden")
    set_strip("all")
    set_optimize("faster")
end

I need full projects and I don't have time to create them one by one.

paulross80 commented 1 day ago

Sorry. What do you mean by full project? a zip file? a public repo?

SirLynix commented 1 day ago

I think either would be fine, the idea is to be able to reproduce the bug in less than two minutes

waruqi commented 1 day ago

Sorry. What do you mean by full project? a zip file? a public repo?

a zip file with your all project files, you can upload it as issue attachment

paulross80 commented 17 hours ago

I see, thank you. Here is the project template_module_not_found.zip

waruqi commented 14 hours ago

It works for me on my fedora/gcc.
