Installation from GitHub on Cygwin32

This page describes the installation of Singular from the latest sources from GitHub on Windows 32-bit systems using Cygwin.

Use this if you need a feature introduced after the last release or if you want to develop for Singular.

This version of the instructions was tested on Windows 7 with Singular 4.

1. Run setup-x86.exe and install (in addition to the standard selection) the following packages (you will be asked to resolve dependencies, answer yes):

   a. Tools used to download Singular and other packages:

   git, wget

   b. Tools necessary to compile Singular:

   gcc-core, gcc-g++, automake, make, libtool, libreadline7

   c. Scientific libraries used by Singular:

   libgmp-devel, libmpfr-devel, mpfr

2. Clone Singular from the git repository:

   Create a directory for the Singular binaries we use here Singular4 in your home directory:

   • cd /home
   • mkdir Singular4

   Create a directory for the Singular sources and a temporary directory for third party libraries we use here /home/git/Singular4 and /home/tmp:

   • mkdir tmp
   • mkdir git
   • cd git
   • mkdir Singular4
   • cd Singular4

   Download Singular from the git repository:

   • git clone https://github.com/Singular/Sources.git

   If you want to update to the latest version in the future use git pull and do step 6 (compiling Singular) again.

   Although you can now compile Singular, we strongly recommend to install some more scientific packages (otherwise some features will not be available).

3. Install NTL:

   Download NTL:

   • mkdir ntl
   • cd ntl
   • wget http://www.shoup.net/ntl/ntl-6.0.0.tar.gz
   • tar -xvf ntl-6.0.0.tar.gz
   • cd ntl-6.0.0
   • cd src

   Compile NTL and install into the folder tmp in your home directory:

   • ./configure DEF_PREFIX=/home/tmp NTL_GMP_LIP=on
   • make
   • make install

   Return to the folder Singular4

   • cd ../../../

4. Install CDDLIB:

   Download CDDLIB:

   • mkdir cddlib
   • cd cddlib
   • wget ftp://ftp.ifor.math.ethz.ch/pub/fukuda/cdd/cddlib-094g.tar.gz
   • tar -xvf cddlib-094g.tar.gz
   • cd cddlib-094g

   Compile cddlib and install into the folder tmp in your home directory:

   • ./configure --prefix=/home/tmp
   • make -j 2
   • make install

   Return to the folder Singular4:

   • cd ../../

5. Install FLINT:

   Create a directory and download FLINT:

   • mkdir flint
   • cd flint
   • git clone git://github.com/wbhart/flint2.git flint2
   • cd flint2

   Compile flint and install into the folder tmp in your home directory

   • ./configure --with-gmp=/usr --prefix=/home/tmp --disable-shared --with-mpfr=/usr
   • make -j 2
   • make install

   Return to the folder Singular4

   • cd ../../

6. Download and install 4ti2 (used by some Singular commands for lattice computations):

   Create a directory and download 4ti2:

   • mkdir 4ti2
   • cd 4ti2
   • wget http://www.4ti2.de/version_1.6/4ti2-1.6.tar.gz
   • tar xvfz 4ti2-1.6.tar.gz
   • cd 4ti2-1.6

   Compile 4ti2:

   • ./configure
   • make
   • make install (requires root permissions, if you don't have ask your administrator to install 4ti2)

   Return to the folder Singular4:

   • cd ../../

7. Compile Singular:

We specify the location of NTL, FLINT and the location to install the Singular binaries.

• cd Sources
• ./autogen.sh
• ./configure --without-python --with-ntl=/home/tmp --with-flint=/home/tmp --prefix=/home/Singular4
• make -j 2
• make install

8. Run the Singular binary (this should now be located in the folder Singular4 in your home directory):

   • cd /home
   • ./Singular4/bin/Singular

9. If you want to use the plotting tools Surfer and Surf follow these [instructions](Installation of Surfer on Cygwin32).
