clang module 编译出现错误 fatal error: 'mm_malloc.h' file not found

[jingyu9575]

Xmake 版本

v2.9.1+HEAD.0c79f6162

操作系统版本和架构

Windows 11 version 23H2

描述问题

使用 clang 编译器和 C++ module 时，添加#include ，编译出现错误：fatal error: 'mm_malloc.h' file not found

#4575 中已将clang-scan-deps命令的clang改为绝对路径（增加了 envs = os.getenvs() 选项），但最新版本中rules/c++/modules/modules_support/clang/compiler_support.lua 的212行又没有了这个选项，导致问题再次出现。

测试发现添加 envs = os.getenvs(), force = true （防止缓存）可以暂时解决这个问题。

期待的结果

无错误

工程配置

xmake.lua

target("hello-core")
set_kind("binary")
add_files("src/*.cpp", "src/*.cppm")

src/main.cpp

import test;

#include <iostream>

int main() {
}

src/test.cppm

module;
export module test;

附加信息和错误日志

xmake f --toolchain=clang

尝试添加 c++20，还是有相同问题：

Try adding c++20, still have the same problem:

2148980 这个 patch 给 revert 了。

刚恢复了，再试试，xmake update -s dev

#4575 has changed the clang of the clang-scan-deps command to an absolute path (envs = os.getenvs() option added), but in the latest version Line 212 of rules/c++/modules/modules_support/clang/compiler_support.lua does not have this option, causing the problem to reappear.

2148980 This patch is revert.

Just restored, try again, xmake update -s dev
