Building

First, make sure you clone this repository.
Then, deflate cantrbry.tar.bz2. If you work on Windows, you're going to need to deflate zlib.tar.bz2 and lz4.tar.bz2.

git clone https://github.com/taqu/cpprcoder.git
cd cpprcoder/test
tar jxvf cantrbry.tar.bz2

Next,

mkdir build
pushd build
cmake -DUSE_SIMD=1 ..
