配置Eclipse CDT或Codeblocks以獲取LLVM IR intellisense

Question

我想配置Eclipse（或Codeblocks），這樣當我編寫一個pass時，我至少可以利用Intellisense（即使直接從Eclipse內部構建傳遞也是不可能的）。 更新：一旦我在Eclipse中啟用基於解析的建議 ，我至少得到了一些智能感知（詳情如下）

到目前為止，我已經將Eclipse配置為使用clang來編譯簡單的C ++程序。

為了獲得LLVM傳遞的intellisense，我將/usr/local/include到Includes目錄並嘗試了代碼：

#include <iostream>
#include <llvm/IR/Function.h>

using namespace std:
int main() {
    cout << "Hello World" << endl;
    return 0;
}

它在#include <llvm/IR/Function.h>本身沒有失敗（即它可以找到這個頭文件），但是在包含后續文件時，給了我

/usr/local/include/llvm/Support/DataTypes.h:58:3: error: "Must #define __STDC_LIMIT_MACROS before #including Support/DataTypes.h"

任何關於我如何制作它的指示至少給我智能感知？

更新： Eclipse確實給了我intellisense（至少其中一些），我必須在窗口中檢查基於解析的提議 - >首選項 - > C / C ++ - >編輯器 - >內容輔助 - >高級 （默認情況下未選中） 。

Answer 1

這不是直接回答問題，但它將確保您擁有正確工作的構建環境。 它特定於代碼塊。

首先檢查llvm的源代碼樹（直接從入門指南中獲取）：

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

刪除任何你不喜歡的東西。

然后在llvm目錄外創建一個目錄：

 cd ..
 mkdir build 

將目錄（cd）更改為並運行：

 cd build 
 cmake -g "CodeBlocks - Unix Makefiles" <your configure options> ../llvm 

假設llvm共享根路徑，否則將../llvm行更改為正確的路徑。 然后在code :: blocks中將其作為現有項目打開。

如果一切順利，您的構建環境將正確設置並且代碼完成應該可行。
