	GiNaC Real Algebra package

How to install GiNaCRA on MacOS X

1. Install Homebrew.
2. Make sure, you have a GCC version greater than 4.4. If not, execute:

   brew install https://raw.github.com/Homebrew/homebrew-dupes/master/gcc.rb
rm -v /usr/bin/{cc,gcc,c++,g++}
ln -sv /usr/local/bin/gcc-4.x /usr/bin/cc
ln -sv /usr/local/bin/gcc-4.x /usr/bin/gcc
ln -sv /usr/local/bin/c++-4.x /usr/bin/c++
ln -sv /usr/local/bin/g++-4.x /usr/bin/g++

   Note that 4.x is the GCC version installed by Homebrew. If the installation path of GCC is /usr you can omit the local from the instructions above.
3. Install GiNaC and CMake with Homebrew:

   brew install ginac
brew install cmake

   If you encounter problems installing GiNaC with Homebrew, install its dependencies and install GiNaC from source:

   brew install readline && brew install cln
tar xvf ginac-*.tar.gz
cd ginac-*
mkdir build
cd build
../configure
make
make install

4. Download GiNaCRA and perform the following steps to build and install:

   tar xvf ginacra-*.tar.gz
cd ginacra-*
mkdir build
cd build
cmake ..
make
make install
