7. 编译安装Fastcomp(LLVM + Clang)
|
||
|
||
```
|
||
mkdir myfastcomp
|
||
cd myfastcomp
|
||
git clone https://github.com/kripken/emscripten-fastcomp
|
||
cd emscripten-fastcomp
|
||
git clone https://github.com/kripken/emscripten-fastcomp-clang tools/clang
|
||
mkdir duild
|
||
cd build
|
||
cmake .. -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86;JSBackend" -DLLVM_INCLUDE_EXAMPLES=OFF -DLLVM_INCLUDE_TESTS=OFF -DCLANG_INCLUDE_EXAMPLES=OFF -DCLANG_INCLUDE_TESTS=OFF // 使用cmake配置（cmake或configure二选一）
|
||
../configure --enable-optimized --disable-assertions --enable-targets=host,js // 使用configure配置（cmake或configure二选一）
|
||
cat /proc/cpuinfo | grep "^cpu cores" | uniq // 查询CPU核心数量，充分利用多核可以加快编译速度
|
||
make -j2 // 上步查到是2核，所以我用-j2参数，慢慢等待吧。。。
|
||
```
|
||
|
||
8. `git clone https://github.com/kripken/emscripten.git //复制Emscripten`
|
||
|
||
9. 修改配置文件~/.emscripten，将LLVM_ROOT设置为第7步的目录`.../myfastcomp/emscripten-fastcomp/build/bin`
|
||
|
||
10. `./emcc -v //在emscripten目录运行此命令，如果没报错即为安装正确`
|
||
|
||
11. `./emcc tests/hello_world.c //如果没报错即为运行正确`
