无法找到std模块 #5615

Perdixky · 2024-09-13T10:29:01Z

Xmake 版本

xmake v2.9.4+HEAD.e85b001

操作系统版本和架构

Linux Perdixky-PC 6.6.36.6-microsoft-standard-WSL2+ #1 SMP PREEMPT_DYNAMIC Fri Sep 6 16:36:32 CST 2024 x86_64 x86_64 x86_64 GNU/Linux

描述问题

我已经安装了clang-19

> clang-19 --version
Ubuntu clang version 19.1.0 (++20240903024228+0c641568515a-1~exp1~20240903144250.30)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/lib/llvm-19/bin

但是我使用xmake的时候

> xmake
[ 50%]: cache compiling.release test.cpp
error: test.cpp:2:8: fatal error: module 'std' not found
    2 | import std;
      | ~~~~~~~^~~
1 error generated.
  > in test.cpp

期待的结果

我希望可以解决这个问题

工程配置

set_languages("c++23")
target("test")
    set_kind("binary")
    add_files("test.cpp")
    set_toolset("cc", "clang-19")
    set_toolset("cxx", "clang++-19")
    set_toolset("ld", "clang++-19")

附加信息和错误日志

Title: clang toolchain cannot be configured

waruqi · 2024-09-18T15:24:39Z

set_toolset 删了，然后试下：

xmake f --toolchain=clang-19 --runtimes=c++_shared -cvD
xmake -rvD

不行就给下完整 logs

建议你还是直接自己下载 llvm 包，切到 llvm toolchain 去试下，linux 安装的 Clang 不一定带 std module 的，也没有 clang-scan-deps

如果用系统的，libc++, libc++-abi 包也得自己装好

Issues-translate-bot · 2024-09-20T13:00:59Z

Bot detected the issue body's language is not English, translate it automatically.

It is recommended that you download the llvm package directly yourself and switch to the llvm toolchain to try it. Clang installed on Linux may not come with std module.

你配置的不对，纯 cpp 没模块文件，参考这个配置

https://github.com/xmake-io/xmake/blob/dev/tests/projects/c%2B%2B/modules/stdmodules_cpp_only/xmake.lua

Issues-translate-bot · 2024-09-21T08:06:28Z

Your configuration is wrong. Pure cpp has no module files. Please refer to this configuration.

set_policy("build.c++.modules", true)

你装的不完整，不要用 apt 系统安装 llvm ，直接从 llvm 官网，下载安装包，然后指定 sdk 使用。

你又切回 gcc 了。没指定 llvm toolchain

我使用 linuxbrew 安装的 llvm 也没有办法找到 std 模块。

linuxbrew 安装的 llvm 确实带有 std 模块，但是 xmake 无法找到

Issues-translate-bot · 2024-10-17T03:38:42Z

I installed llvm using linuxbrew and there is no way to find the std module.

The llvm installed by linuxbrew does come with the std module, but xmake cannot find it

怎么设置？

libc++ 装了么，然后切到 libc++ xmake f --toolchain=llvm --runtimes=c++_shared -c

libc++ 装了么，然后切到 libc++ xmake f --toolchain=llvm --runtimes=c++_shared -c

sudo apt install libc++-dev libc++abi-dev

安装好后可以了，总算在linux上跑成功了
