LLVM-3.5 —— 01记，编译 LLVM 3.5.0 clang and clang-query

包括编译：clang clang-tools-extra

0, prepare env

sudo apt install llvm
sudo apt install clang

使用最新的g++ 会出错。

1, source code

$ git clone --recursive
$ cd llvm-project

$ git checkout llvmorg-3.5.0
$ cp -r ./clang ./llvm/tools/
$ mkdir llvm/tools/clang/tools/extra
$ cp -r ./clang-tools-extra/* llvm/tools/clang/tools/extra/
$ ls llvm/tools/clang/tools/extra/

2,修改源代码

增加了一个 public:

(base) hipper@hipper-G21:~/llvm_3_4_0_ex/browse/llvm-project$ git diff
diff --git a/llvm/include/llvm/ADT/IntrusiveRefCntPtr.h b/llvm/include/llvm/ADT/IntrusiveRefCntPtr.h

3,cmake 配置 llvm

3.1 用 cmake 配置 构建 llvm

$ cd llvm-project

$ mkdir build

$ mkdir ../local_d

$ cd build

$ cmake -G "Unix Makefiles"            \
-DCLANG_ENABLE_STATIC_ANALYZER=1     \
-DLLVM_ENABLE_ASSERTIONS=On          \
-DCMAKE_BUILD_TYPE=Debug             \
-DCMAKE_INSTALL_PREFIX=/home/hipper/llvm_3_4_0_ex/browse/local_d   \
-DLLVM_ENABLE_LIBCXX=1               \
-DLLVM_ENABLE_PROJECTS="all"         \
 ../llvm

3.2 使用configure 来配置构建llvm

跟上一篇记录的 llvmorg-3.4.0 的构建过程一样

./configure --prefix=/home/hipper/llvm_3_4_0_ex/browse/local_d

make -j

make install

4， 编译安装

make -j install

5，测试

clang-query
