cpp-ethereum构建错误

Question

我在Linux (centOS)中从git中克隆出cpp-Linux，如发展cmake误差中所建议的那样

git clone https://github.com/ethereum/cpp-ethereum 

cd cpp-ethereum

git checkout -b develop

git submodule update --init --recursive

mkdir -p build
cd build
cmake .. 

当我运行cmake命令时

    -- The C compiler identification is GNU 4.8.5
    -- The CXX compiler identification is GNU 4.8.5
    -- Check for working C compiler: /usr/bin/cc

如何解决这个问题？甚至日志文件也没有关于错误的适当细节。

看起来构建过程在这提交中被破坏了。他们很可能很快就会修好，但现在你可以

cd cpp-ethereum
git checkout 5669c209f4f8dbb7dc3f744e8e2a9c92f1104ca3

然后继续进行构建过程的其余部分。
