OLD AND OBSOLETE ---------

This installation manual may be found at:Ubuntu forums. Just in case it is copied here and slightly modified. Installation of PSFEX is added. It will work under Ubuntu 8.04 32-bit.

SEXTRACTOR part I

• SExtractor

Download sextractor-2.8.6.tar.gz from http://astromatic.iap.fr/software/sextractor

tar zxvf sextractor-2.8.6.tar.gz
cd sextractor-2.8.6/

FFTW

• FFTW

Download fftw-3.2.2.tar.gz from http://www.fftw.org/download.html via http

cd sextractor-2.8.6/
wget http://www.fftw.org/fftw-3.2.2.tar.gz . 
tar zxvf fftw-3.2.2.tar.gz
cd fftw/
./configure --enable-threads
# If compiler problems reported - do sudo synaptic and find and install gfortran and then do ./configure --enable-threads again 
make
sudo make install

CLAPACK

• CLAPACK

Download clapack.tgz from http://www.netlib.org/clapack/clapack.tgz

cd /home/[user]/
wget http://www.netlib.org/clapack/clapack.tgz .
gunzip -c clapack.tgz | tar xvf -
cd CLAPACK-3.2.1/
cp make.inc.example make.inc

In file: make.inc
replace F2CLIB = ../../F2CLIBS/libf2c.a with F2CLIB = F2CLIBS/libf2c.a (in 2 places)
In file: CLAPACK-3.2.1/TESTING/LIN/Makefile
replace $(F2CLIB) with ../../$(F2CLIB); replace $(BLASLIB) with ../../BLAS/SRC/$(BLASLIB)
In file: CLAPACK-3.2.1/TESTING/EIG/Makefile
replace $(F2CLIB) with ../../$(F2CLIB); replace $(BLASLIB) with ../../BLAS/SRC/$(BLASLIB)
In files: CLAPACK-3.2.1/BLAS/TESTING/Makeblat[1-3]
replace $(BLASLIB) with ../SRC/$(BLASLIB); replace $(F2CLIB) with ../../$(F2CLIB)

• sed -i s/"\$(F2CLIB)"/"..\/..\/\$(F2CLIB)"/g Makeblat[1-3] # Something like this may help

 make f2clib  # If it exits with errors -- fix them (it could be only paths like above) before proceeding
 sudo make

ATLAS

• ATLAS

sudo apt-get install libblas-doc libblas3gf libblas-dev libblas-test gfortran
sudo synaptic (search by lapack and libgsl)

INSTALL: atlas3-base atlas3-doc atlas3-sse2 lapack3 libatlas3gf-sse2 libblas3gf libblas-test libgsl0-dbg libgsl0ldbl liblapack3gf refblas3

Download atlas3.8.3.tar.gz from http://sourceforge.net/projects/math-atlas/files/

cd /usr/
sudo wget http://sourceforge.net/projects/math-atlas/files/Stable/3.8.3/atlas3.8.3.tar.gz/download .
sudo zxvf atlas3.8.3.tar.gz 
cd ATLAS/
sudo mkdir linux
cd linux
sudo /usr/bin/cpufreq-selector -g performance   # not important, skip 
sudo ../configure -b 32 --with-netlib-lapack=/home/[user]/CLAPACK-3.2.1/lapack_LINUX.a #  Put your user name
sudo make build
sudo make check

Successful cmd will list 2 errors that should be ignored (as it says) like this:
DONE BUILDING TESTERS, RUNNING:
SCOPING FOR FAILURES IN BIN TESTS:
fgrep -e fault -e FAULT -e error -e ERROR -e fail -e FAIL \
bin/sanity.out
8 cases: 8 passed, 0 skipped, 0 failed
4 cases: 4 passed, 0 skipped, 0 failed

DONE
make[1]: Leaving directory `/usr/ATLAS/linux'

sudo make time
sudo make install

Now the libraries should be at /usr/local/atlas/.

SEXTRACTOR part II

• CONTINUE WITH SEXTRACTOR

cd ~/sextractor-2.8.6/
./configure --with-atlas=/usr/local/atlas/lib --with-atlas-incdir=/usr/local/atlas/include

If an error occures: configure: error: CBLAS/LAPack was compiled without multithreading support! Exiting., do

sudo ./configure --disable-threads --with-atlas=/usr/local/atlas/lib --with-atlas-incdir=/usr/local/atlas/include
# It seems to me that this error occurs if you have a single CPU. With Core Duo processor I haven't experienced any problems.

And then (in both cases) continue with

sudo make
sudo make install

This should do the trick. Further, for installation of GIM2D:
Download fuzzy.v32.linux.tar.gz from https://www.astrosci.ca/users/GIM2D/installation.html
Save it in : /iraf/iraf/unix/

tar -xvpf fuzzy.tar

Add 2 lines to login.cl in your home dir:
set fuzzy = "/iraf/iraf/unix/fuzzy/"
task $fuzzy.pkg = "fuzzy$fuzzy.cl"

Now, when you start iraf with goiraf (or whatever you are using) you will see new package fuzzy. Enjoy!

PSFEX

• PSFEX

In addition to sextractor, for installation of psfex that makes psfs:

1. Download all .tar.gz files and all stand alone files (The easiest way: check trunk dir and click on the Tarball right and save file)
2. Unpack the file: gunzip psfex-trunk.r149.tar.gz | tar xvf -
3. Change configure to be executable if necessary and the dir name to psfex (if you want)
4. Enter psfex/ and run

 sudo ./configure --with-atlas=/usr/local/atlas/lib --with-atlas-incdir=/usr/local/atlas/include
 #  If it says sth. like fftw -- single precision not found blah, blah GO BACK to fftw dir and do 
  ./configure --enable-threads
  ./configure --enable-single --enable-threads
  sudo make
  sudo make install 
 #And then return to psfex dir and proceed with:
 sudo ./configure --disable-threads --with-atlas=/usr/local/atlas/lib --with-atlas-incdir=/usr/local/atlas/include

5. Run

 sudo make 

• If it reports a problem in seeing 8 spaces instead of tabs, do

 sed -i s/"        "/"\t"/g Makefile

6. continue with

 sudo make install 

Good luck with the rest...
