Various build instructions

build_instructions.txt

GCC on orga
===========

First, download and install GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.  Also ISL.

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
unset LD_LIBRARY_PATH
unset CXXFLAGS



cd gmp-4.3.2
./configure --prefix=$HOME/opt
make -j 8 install

cd isl-0.12.2
./configure  --prefix=$HOME/opt --with-gmp-prefix=$HOME/opt
make -j 8 install

cd mpfr-2.4.2
./configure --prefix=$HOME/opt --with-gmp=$HOME/opt
make -j 8 install

cd mpc-0.8.1
./configure --prefix=$HOME/opt --with-gmp=$HOME/opt --with-mpfr=$HOME/opt
make -j 8 install

export LD_LIBRARY_PATH=$HOME/opt/lib:$HOME/opt/lib64

cd gcc-4.9.1
./configure --enable-languaes=c,c++,fortran --disable-multilib --prefix=$HOME/opt --with-gmp=$HOME/opt --with-mpfr=$HOME/opt --with-mpc=$HOME/opt --with-isl=$HOME/opt 
make -j 8
make install


PETSc on orga
=============

Using gcc 4.7 installed in /home/memmett/gcc-4.7:

export PATH=/home/memmett/gcc-4.7/bin:$PATH
unset CXXFLAGS
cd /home/memmett/projects/petsc
./configure CXXFLAGS=-D__USE_XOPEN2K8 --with-shared-libraries --with-cmake=/home/memmett/opt/bin/cmake --download-fblaslapack --with-c2html=0 --with-sowing=0
make PETSC_DIR=/home/memmett/projects/petsc PETSC_ARCH=arch-linux2-c-debug all


Subsequently, to build a PETSc example:
make PETSC_DIR=/home/memmett/projects/petsc PETSC_ARCH=arch-linux2-c-debug exXX


Now that I have gcc4.9:


./configure --with-shared-libraries --with-cmake=/home/memmett/opt/bin/cmake --download-fblaslapack --download-c2html --download-sowing


MPICH2
======

Debugging:  --
Optimized:  --enable-fast=all,-O3


Compile:
$ PREFIX=$HOME/venv/killdevil_mpich2
$ ./configure --prefix=$PREFIX --enable-shared --without-mpe 
$ make
$ make install


FFTW3
=====

Compile:
$ PREFIX=$HOME/venv/killdevil_sysmpich2
$ ./configure --prefix=$PREFIX --enable-shared --enable-threads --enable-openmp --enable-mpi  --enable-sse2 
$ make
$ make install

$ pip install PyFFTW3



h5py
====

$ export HDF5_DIR=$PREFIX
$ pip install h5py


HDF5
====

Fortran support: --enable-fortran
Shared lib:      --enable-shared
MPI:             --enable-parallel

May need to do: 

$ export FC=mpif90
$ export CC=mpicc

Then, compile:

$ export PREFIX=$HOME/opt
$ ./configure --prefix=$PREFIX --enable-shared --enable-fortran --enable-parallel
$ gmake -j 4
$ gmake install


PETSc on OpenBSD
================

Install prerequisites:

$ sudo pkg_add py-scipy
$ sudo pkg_add openmpi
$ sudo pkg_add cmake
$ sudo pkg_add mercurial

Checkout the source:

$ hg clone http://petsc.cs.iit.edu/petsc/petsc-dev
$ cd petsc-dev

Configure:

$ export PETSC_DIR=$PWD
$ ./config/configure.py --with-shared-libraries --with-dynamic-loading --with-fortran=0 --with-x=0 --with-cmake=/usr/local/bin/cmake

Build:

$ cd arch-openbsd*
$ make

Test:

$ cd ..
$ make test

PETSc on Debian
===============

Similar to above, except:

$ ./config/configure.py --with-shared-libraries --with-dynamic-loading --with-fortran=0 --with-x=0 --with-cmake=/usr/bin/cmake --with-c2html=0

PETSc on Fedora
===============

./config/configure.py --with-shared-libraries --with-dynamic-loading --with-fortran=0 --with-cmake=/usr/bin/cmake --with-c2html=0 --ldflags='-L/usr/lib64'



petsc4py on OpenBSD
===================

Install Cython:

$ pip install cython

Checkout the source:

$ hg clone https://petsc4py.googlecode.com/hg/ petsc4py
$ cd petsc4py

Build and install:

$ python setup.py build
$ python setup.py install

Test:

$ python tests/test-vec.py
