Installing Octave with UMFPACK from Source

if you are not using Ubuntu and need to compile the UMFPACK manually, download the SuiteSparse package at this page. I didn’t use METIS, so I need to disable it first. Follow the instruction at the README.txt on how to disable it. This is the step btw:

1. from the SuiteSparse directory, go to UFconfig directory and edit UFconfig.mk, and uncomment this option
   
# If you use CHOLMOD_CONFIG = -DNPARTITION then you must use the following
# options:
METIS_PATH =
METIS =

   and add add this line
   
CHOLMOD_CONFIG = -DNPARTITION

2. Since I’m compiling for linux, I choose this compiler alternative option.
   
CFLAGS = -O3 -fexceptions -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -L/usr/li
b/gcc/x86_64-redhat-linux/4.1.1/

   Somehow I got error that it couldn’t fine libgfortran, so I need to specify the location with the -L option.
3. Go back to SuiteSparse directory and type “make”. It will compile and run the test
4. run this script SuiteSparse direcotry to install headers and libraries to your local directory.

5. Go to octave-3.0.0 source directory. and type
   
./configure CPPFLAGS=-I$HOME/usr/local/include/suitesparse LDFLAGS=-L$HOME/usr/local/lib/ --prefix=$HOME/programs/Octave3.0

   where I decide to install it into my $HOME/programs/Octave3.0 directory.
