Install Sage's dependencies from conda-forge and activate the environment

# install sage and its dependencies
conda create -n sage sage future
# keep the dependencies but drop sage itself
conda remove -n sage --force sage sagelib

source activate sage

Install newer versions for the latest Sage

Singular

conda install singular=4.1.0.p3

cypari2

conda install cypari2

cysignals

conda install cysignals

Install Sage's dependencies which are not in conda-forge yet

# if your gcc is >4 then there will be incompatibilities with the packages that come from conda
conda install -n root gcc
# tools needed to build packages for conda
conda install -n root conda-build

Pynac

The latest pynac-0.7.7 is not in conda-forge yet, see conda-forge/pynac-feedstock#4

# on cocalc, there is an issue with conda and encrypted/long directory names.
# To work around, do
# mkdir /tmp/conda-bld
# and add --croot=/tmp/conda-bld to the build and --channel=file:///tmp/conda-bld to the install call below
git clone -b pynac077 https://github.com/saraedum/pynac-feedstock.git
conda build --python=27 pynac-feedstock
conda install --use-local pynac=0.7.7

Conway Polynomials

The latest conway polynomials package is not in conda-forge yet, see conda-forge/sagemath-db-conway-polynomials-feedstock#2

git clone https://github.com/saraedum/sagemath-db-conway-polynomials-feedstock.git
conda build --python=27 sagemath-db-conway-polynomials-feedstock
conda install --use-local sagemath-db-conway-polynomials

Cython

We need to patch the cython that's in conda-forge, see conda-forge/cython-feedstock#20

git clone -b create_extension https://github.com/saraedum/cython-feedstock.git
conda build --python=27 cython-feedstock
conda install --use-local cython=0.25.2

Build Sage

git clone -b dev https://github.com/saraedum/sagelib-feedstock
git clone -b develop https://github.com/sagemath/sage.git
