我想配置Eclipse(或代码块),以便在编写过程时,至少可以利用Intellisense(即使无法直接从Eclipse内部构建过程)。 更新:一旦我在Eclipse中启用了基于解析的建议(以下详细信息),我至少会得到一些智能感知。
到目前为止,我已经将Eclipse配置为使用clang来编译简单的C++程序。
为了获得LLVM传递的智能感知,我在Includes目录中添加了/usr/local/include
并尝试了以下代码:
#include <iostream>
#include <llvm/IR/Function.h>
using namespace std:
int main() {
cout << "Hello World" << endl;
return 0;
}
它不会在
#include <llvm/IR/Function.h>
本身上失败(即,它可以找到此头文件),但是在包含后续文件时,给了我/usr/local/include/llvm/Support/DataTypes.h:58:3: error: "Must #define __STDC_LIMIT_MACROS before #including Support/DataTypes.h"
至少有任何关于如何实现它的建议可以让我至少拥有智能感知能力吗?

最佳答案
这不是直接回答问题,而是可以确保您具有正确运行的构建环境。它特定于代码块。
首先 checkout llvm的源树(直接从入门guide中获取):
git clone http://llvm.org/git/llvm.git
cd llvm/tools
git clone http://llvm.org/git/clang.git
cd ..
cd projects
git clone http://llvm.org/git/compiler-rt.git
git clone http://llvm.org/git/libcxx.git
git clone http://llvm.org/git/libcxxabi.git
git clone http://llvm.org/git/test-suite.git
git clone http://llvm.org/git/openmp.git
删除所有您不喜欢的内容。
然后在llvm目录之外创建一个目录:
cd ..
mkdir build
将目录(cd)更改到该目录并运行:
cd build
cmake -g "CodeBlocks - Unix Makefiles" <your configure options> ../llvm
假设llvm共享根路径,否则将../llvm行更改为正确的路径。然后将其作为现有项目在code::blocks中打开。
如果一切顺利,则说明您的构建环境已正确设置,并且代码补全应该可以正常工作。
