There are two public SVN repositories that host casa-core
:
Unfortunately these two repositories are independent of each other, do not contain identical information, and there is significant loss of information when commits applied to one are moved to the other.
It is necessary to choose one of these to work with; at the time of
writing casa
is only compatible with the NRAO version of the
casa-core
therefore only that repository can be used.
I have a bzr branch of the casa-core repository (sing the bzr-svn plugin), and I’ve made a branch off this branch with some small build improvements. People in Cambridge can get this branch at: appcd:~bnikolic/d/n/casa-core-nrao/build-improve .
If there is interest in this branch from outside of Cambridge please get in touch and I will be happy to put it somewhere public.
Here are the commands to build some of the dependencies necessary for
casa-core
. I have been able to install the remainder of the
dependecies using system-wide package managers for the systems I’ve
been working on, but you may find you need to install some additional
packages in this way too.
# Destination directory
export CCINSTALLDIR=/home/bnikolic/p/casa-main
#HDF5
wget http://www.hdfgroup.org/ftp/HDF5/current/src/hdf5-1.8.3.tar.gz
tar xzvf hdf5-1.8.3.tar.gz
cd hdf5-1.8.3
./configure --enable-cxx --prefix=$CCINSTALLDIR
make && make install && cd ..
#WCSlib
wget ftp://ftp.atnf.csiro.au/pub/software/wcslib/wcslib.tar.bz2
tar xjvf wcslib.tar.bz2
cd wcslib-4.4.4
./configure --prefix=$CCINSTALLDIR
make && make install && cd ..
Note the philosophy here is to install all the dependencies and then
casa-core
itself into a single directory tree rooted at
CCINSTALLDIR
. This makes it significantly easier to specify the
linker search paths and similar but it does make it hard to
mix-and-match different versions of dependency packages.
I did not need to build FFTW3 since system-wide libraries were appropriate, but if you do need to do so, the following lines should do the trick:
# Destination directory
export CCINSTALLDIR=/home/bnikolic/p/casa-main
# FFTW3
#
# Note that you need build both the single-precision and
# double-precision versions (that is why there are two invocations
# below), and they all should have the multi-threaded facility.
wget http://www.fftw.org/fftw-3.2.2.tar.gz
tar xzvf fftw-3.2.2.tar.gz
cd fftw-3.2.2
./configure --prefix=$CCINSTALLDIR --enable-single --enable-shared --enable-threads --with-gcc-arch=core2 --enable-sse2
make && make install
./configure --prefix=$CCINSTALLDIR --enable-shared --enable-threads --with-gcc-arch=core2 --enable-sse2
make && make install
There are several thing to note:
-march
flag
corrects this problemThe main body of casa-core
itself can be built very easily using
following commands:
# Destination directory
export CCINSTALLDIR=/home/bnikolic/p/casa-main
./batchbuild.py install hdf5root=$CCINSTALLDIR wcsroot=$CCINSTALLDIR prefix=$CCINSTALLDIR
