经过几天的努力,终于解决了在CentOS上编译CoreCLR的问题。最终发现问题是CMAKE_C_FLAGS的设置引起的。
只要在“src/pal/tools/clang-compiler-override.txt”中删除“SET (CMAKE_C_FLAGS_INIT "-Wall -std=c11") ”,在“src/pal/tests/CMakeLists.txt”添加“SET (CMAKE_C_FLAGS "-Wall -std=c11")”,就能编译了。
下面分享一下在CentOS上编译CoreCLR的操作步骤。
所用的CentOS版本7.0。
1)下载llvm的源代码
http://llvm.org/releases/3.5.0/llvm-3.5.0.src.tar.xz mv llvm-3.5.0.src llvm
2)下载clang的源代码
cd llvm/tools wget http://llvm.org/releases/3.5.0/cfe-3.5.0.src.tar.xz tar xf cfe-3.5.0.src.tar.xz mv cfe-3.5.0.src clang
3)下载compiler-rt的源代码
cd ../projects wget http://llvm.org/releases/3.5.0/compiler-rt-3.5.0.src.tar.xz tar xf compiler-rt-3.5.0.src.tar.xz mv compiler-rt-3.5.0.src compiler-rt
4)下载libcxxabi的源代码
wget http://llvm.org/releases/3.5.0/libcxxabi-3.5.0.src.tar.xz tar -xf libcxxabi-3.5.0.src.tar.xz mv libcxxabi-3.5.0.src.tar.xz libcxxabi
5)下载libcxx的源代码
wget http://llvm.org/releases/3.5.0/libcxx-3.5.0.src.tar.xz tar xf libcxx-3.5.0.src.tar.xz mv libcxx-3.5.0.src libcxx
6)配置编译选项
cd .. ./configure --enable-optimized CC=gcc CXX=g++
7)编译llvm
make -j2
8)安装编译好的llvm
make install
9)签出CoreClr的源代码进行编译
git clone https://github.com/dotnet/coreclr.git cd coreclr ./build.sh
10)解决"Native context type is not known"编译错误
编译过程中出现如下的错误:
-- Check size of siginfo_t -- Check size of siginfo_t - failed -- Check size of ucontext_t -- Check size of ucontext_t - failed ... [ 0%] Building CXX object src/palrt/CMakeFiles/palrt.dir/bstr.cpp.o In file included from /data/git/coreclr/src/pal/src/arch/i386/context.cpp:25: /data/git/coreclr/src/pal/src/include/pal/context.h:40:2: error: Native context type is not known on this platform!
修改 src/pal/tools/clang-compiler-override.txt 文件,去掉 SET (CMAKE_C_FLAGS_INIT "-Wall -std=c11") 可以解决这个问题。
10)解决"use of undeclared identifier"编译错误
继续编译过程中出现如下的错误:
/data/git/coreclr/src/pal/tests/palsuite/c_runtime/wprintf/test2/test2.c: 31:15: error: use of undeclared identifier ‘u‘ DoStrTest(u"foo %s", u"bar", u"foo bar");
在 src/pal/tests/CMakeLists.txt 中添加 SET (CMAKE_C_FLAGS "-Wall -std=c11") 可以解决这个问题。
11)大功告成
Repo successfully built. Product binaries are available at /data/git/coreclr/binaries/Product/amd64/debug
