This is a helper library that lets Python call NTL through CFFI. It is used in BCCGP-sqrt for polynomial multiplication.
On Debian-ish systems, you'll probably need the following:
apt-get install build-essential g++ automake pkg-config \
libtool libtool-bin libgmp-dev
This library also requires NTL 10.x. This might be as simple as
apt-get install libntl-dev
But several distributions (including Debian 9.x) do not package recent enough versions. Lucky you! You get to build a newer version.
You only need to do this if your distribution doesn't provide NTL 10.x. If you've already got it, you can skip to the next section.
We'll install this library in $HOME/toolchains, so first we need to make
that directory, get the source, and unpack it:
mkdir -p $HOME/toolchains/src
cd $HOME/toolchains/src
wget http://shoup.net/ntl/ntl-10.5.0.tar.gz
tar xzvf ntl-10.5.0.tar.gz
cd ntl-10.5.0/src
Now we're going to configure and build NTL. The following options are known
to work, assuming you have a C++14-compatible compiler (e.g., g++ >= 5).
Otherwise, change NTL_STD_CXX14 to NTL_STD_CXX11 immediately below.
./configure DEF_PREFIX=/usr PREFIX=$HOME/toolchains SHARED=on \
NTL_THREAD_BOOST=on NTL_STD_CXX14=on
make -j4 # for example
make install
The above will take a while because it'll run some tuning scripts. Give it five minutes or so.
Now we're ready to build pylaurent:
./autogen.sh
# if you installed NTL in the prior step, use the following command:
./configure --with-ntl=$HOME/toolchains
# otherwise, just call ./configure
make -j4 # for example
If you don't have it installed already, you should first install Python's CFFI package:
apt-get install python-cffi
Now:
cd python
python -m pylaurent
If you don't get any errors, you ought to be all set.
