你先自己分析下生成的 cmakelists.txt 看看哪里有问题。

masx200 commented 1 year ago

我知道问题在哪了,

add_library(leetcode-treenode-cpp STATIC "" TreeNode.ixx test.cpp LeetCodeTreeNodeToString.mpp bfsTravelsal.ixx freeTreeNode.ixx)

是xmake这里没有自动生成需要添加到这个target的文件,手动添加之后就可以了,但是能自动添加更好

waruqi commented 1 year ago

target_sources(leetcode-treenode-cpp PRIVATE )

是这里空的，因为现在 project generator 对 c++20 modules 还没怎么支持。暂时不要去生成带 c++ modules 的 cmakelists

pwqbot commented 1 year ago

对 compile_commands.json 和 makefile 的生成目前也是不支持的吗？

waruqi commented 1 year ago

不支持 只能直接构建

pwqbot commented 1 year ago

目前不支持是因为理论上不可行还是只是暂时没有实现？

waruqi commented 1 year ago

暂时没实现，xmake 主要以直接构建为主，project generator 只是作为额外提供的插件，不是重点。。有时间会陆续改进，但要看个人时间和精力，有优先处理维护其他的特性和问题

pwqbot commented 1 year ago

好的，非常感谢！因为 xmake对module的支持比较全面我正在尝试从 cmake 迁移过来，但是不能生成正确的 compile_commands.json 的话 lsp 就无法工作，无法进行日常开发，我觉得这应该是很多人都会遇到的问题？不知道其他使用xmake module的人如何解决这个问题

首先各家编译器对 c++modules 支持都是不完善的，也就 msvc 勉强可用（但还是有很多的坑和bug），按现在的支持力度，玩玩可以，想用这个去做日常开发，原本就不建议。。不管是编译器支持，配套设施，模块分发，intellisense，ide 支持等都很不完善。趟坑是难免的。。

想要完全日常可用，且跨平台稳定，至少再等几年。我就没见过几个拿这个放进正式项目里面用的，如果还要支持 gcc/clang 的更少了。

xmake 目前只对编译器直接构建，尽可能做到了跨平台可用，并且内部处理了各家编译器可能遇到的一些坑和兼容性问题。

模块分发初步支持，基本可用，但是对 IDE, intellisense 支持暂时还没时间搞。

感谢指导！不过module 带来的好处还是十分吸引人的，后面等支持更完善了再来尝试下。

Clion对模块的智能提示就不错,visual studio加上resharper c++后也还行.模块特性用起来又爽,再加上第四代构建系统简直无敌了好吧. 望作者大大可以投入更多的精力完善对c++模块特性以及IDE的支持.c++的模块真的需要一个简洁又强大的构建系统.

Issues-translate-bot commented 1 year ago

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

Clion's intelligent prompts for modules are good, and visual studio plus resharper c++ is also okay. The module features are cool to use, and the fourth-generation build system is simply invincible. I hope the author can put more effort into improving the features of c++ modules and IDE support. C++ modules really need a simple and powerful build system.

生成 compile_commands 目前支持 c++20 modules ，原本就可以用。。clion 的插件没精力维护，建议用 vscode + clangd

Issues-translate-bot commented 1 year ago

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

Generating compile_commands currently supports c++20 modules, which should work natively. . The plugin of clion has no energy to maintain, it is recommended to use vscode

确实可以正常编译运行+调试,但是clion的智能提示似乎作废 确实可用,但是clion的智能提示似乎无法使用 难道是我配置不当?我参考的是（笔记）如何在 CLion 上调试编译 xmake 项目 - 哔哩哔哩 (bilibili.com)

xmake.lua如下:

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

target("tmp")
    set_kind("binary")
    add_files("src/*.cpp")
    add_files("src/*.ixx")

It is indeed possible to compile and run + debug normally, but the smart prompt of clion seems to be unavailable It does work, but clion's intellisense doesn't seem to work Could it be that my configuration is improper? I refer to (Notes) How to debug and compile xmake projects on CLion - 哔哩哔哩 (bilibili.com)

xmake.lua is as follows:

[

生成 compile_commands 目前支持 c++20 modules ，原本就可以用。。clion 的插件没精力维护，建议用 vscode + clangd

这么说,xmake对vscode的官方支持是最好的吗?最爱JetBrains家的智能提示了,clangd不知道怎么样.

Generate compile_commands currently supports c++20 modules, which can be used natively. . The clion plugin has no energy to maintain, it is recommended to use vscode + clangd

So, is xmake's official support for vscode the best? I love JetBrains' smart tips, but clangd doesn't know how.

忘记把test.ixx贴上去了.png 忘记把test ixx贴上去了

我的错,忘记set_languages("cxx20")了...

My fault, forgot about set_languages("cxx20")...

难道是我配置不当?我参考的是（笔记）如何在 CLion 上调试编译 xmake 项目 - 哔哩哔哩 (bilibili.com)

不是官方视频，这边 intellisense 从没支持过 clion

xmake 生成的 compile_commands 肯定支持 c++20 modules

但是能否让 clion 支持上，怎么配置上，不归这边管。。你自己研究。。

目前能确定的就是 clangd 是支持 c++20 modules 的 compile_commands，并且其他人在 vscode 上配置使用成功过。

Is my configuration wrong? I refer to (notes) How to debug and compile xmake project on CLion - 哔哩哔哩 (bilibili.com)

Not an official video, intellisense has never supported clion here

The compile_commands generated by xmake definitely support c++20 modules

But whether clion can support it or how to configure it is not under the control of this side. . Do your own research. .

What can be determined at present is that clangd supports compile_commands of c++20 modules, and others have successfully configured and used it on vscode.

还是会有小问题,看来我最好还是向CLion官方反馈看看能不能像支持CMake那样直接原生支持XMake,或者直接跑路Rust,苦c++已久... 但是发现了另外一个问题

现在增加了 cmake 对原生 c++ modules 的支持。https://github.com/xmake-io/xmake/pull/4746

1821746019 commented 9 months ago

现在增加了 cmake 对原生 c++ modules 的支持。#4746

那大佬啥时候有空顺便把预编译头和模块冲突的问题解决了

Issues-translate-bot commented 9 months ago

Now adds cmake support for native c++ modules. #4746

When will the boss have time to solve the problem of conflicts between precompiled headers and modules?

看时间，最近估计没空

Look at the time, I guess I won’t be free recently

环境 windows clion vs2022 preview cmake 3.31.0

看起来xmake-ide不直接支持debug，而是生成cmake然后调试。 但是生成的CMakeLists.txt无法使用import std error C2230: could not find module 'std' 看起来是找不到std.ixx，如果能copy过去也许就行了。 以上的理解正确吗？

import std in CMake 3.30 在 CMake 3.30 中导入 std https://www.kitware.com/import-std-in-cmake-3-30/

https://github.com/microsoft/STL/issues/3195#issuecomment-1770283053

if (MSVC)
    string(REGEX REPLACE "\/bin\/Hostx(64|86)\/x(64|86)\/cl\.exe" "" MSVC_ROOT ${CMAKE_CXX_COMPILER})
    configure_file("${MSVC_ROOT}/modules/std.ixx" "${PROJECT_BINARY_DIR}/std.ixx" COPYONLY)
    configure_file("${MSVC_ROOT}/modules/std.compat.ixx" "${PROJECT_BINARY_DIR}/std.compat.ixx" COPYONLY)
endif ()

感觉这个很关键，是一个最后一英里问题，跑通就能很舒服的在clion下配合xmake玩c++ modules
