LLVM库无法引入 #6445

AI1379 · 2025-02-25T08:06:01Z

Xmake 版本

xmake v2.9.8+20250225

操作系统版本和架构

Linux 5.15.167.4-microsoft-standard-WSL2 ArchWSL2

描述问题

无法引入LLVM库。尝试了多种方法均无法实现，或者有其他bug，比如找不到系统头文件等。

使用`xrepo`时

// test.cpp
#include <cstdlib>
#include <iostream>

int main() {
  std::cout << "Hello, World!" << std::endl;
  return EXIT_SUCCESS;
}

-- xmake.lua
set_project("test")

set_version("1.0.0")

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

set_languages("c89", "cxxlatest")

add_requires("llvm", {kind = "library", configs = {mlir = true}})

target("test1")
    set_kind("binary")
    add_files("*.cpp")
    add_packages("llvm", {components = "mlir"})

此时会报错：

error: /usr/include/c++/14.2.1/cstdlib:79:15: fatal error: stdlib.h: No such file or directory
   79 | #include_next <stdlib.h>
      |               ^~~~~~~~~~
compilation terminated.
  > in test.cpp
warning: unknown component(mlir) in add_packages(llvm, {components = {mlir}})

删除xmake.lua中的add_packages后就恢复正常了。

此外，如果改为components = 'clang'就不会有这个warning，但是依然无法编译。

使用`cmake`时

set_project("test")

set_version("1.0.0")

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

set_languages("c89", "cxxlatest")

add_requires(
    "cmake::LLVM",
    {
        alias = "llvm-dev",
        system = true
    }
)

target("test1")
    set_kind("binary")
    add_files("*.cpp")
    add_packages("llvm-dev")

此时运行xmake build -vD后会报错：

然而，如果直接使用CMake：

cmake_minimum_required(VERSION 3.31.5)
project(find_package)
find_package(LLVM REQUIRED )
if(LLVM_FOUND)
   add_executable(test_LLVM test.cpp)
   message(STATUS "LLVM_INCLUDE_DIR: ${LLVM_INCLUDE_DIR}")
   target_include_directories(test_LLVM PRIVATE LLVM_INCLUDE_DIR LLVM_INCLUDE_DIRS LLVM_INCLUDE_DIR LLVM_INCLUDE_DIRS)
   target_include_directories(test_LLVM PRIVATE LLVM_CXX_INCLUDE_DIRS)
   target_link_libraries(test_LLVM PRIVATE LLVM_LIBRARY LLVM_LIBRARIES LLVM_LIBS LLVM_LIBRARY LLVM_LIBRARIES LLVM_LIBS)
endif(LLVM_FOUND)

此时可以正常输出：

期待的结果

至少一项引入llvm的方式可用

Title: LLVM library cannot be imported

star-hengxing · 2025-02-27T13:06:29Z

如果使用系统包管理的 llvm，可以直接 add_requires("llvm") 或者 add_requires("pacman::llvm")

If you use llvm managed by the system package, you can directly use add_requires("llvm") or add_requires("pacman::llvm")

这样确实可以暂时解决引入llvm的问题，但是还是没解决 cmake::LLVM 和 xrepo 那边的问题啊

This can indeed temporarily solve the problem of introducing llvm, but it still does not solve the problem of cmake::LLVM and xrepo.

cmake::LLVM

cmake::xxx 是 hack 实现，大部分情况下不推荐使用。

xrepo::llvm

llvm 每次 ci 全量构建都会浪费很多时间，而且还需要懂打包的人来处理才行，暂时没这么多精力。

Issues-translate-bot · 2025-02-28T14:06:54Z

cmake::LLVM

cmake::xxx is a hack implementation and is not recommended in most cases.

xrepo::llvm

llvm every time you build ci full amount, it will waste a lot of time, and it also requires people who know how to pack it to handle it. I don’t have so much energy for the time being.
