Pre-Compiled Perl Libraries In HEASoft
HEASoft contains several Perl Libraries which provide Perl interfaces to
core libraries such as PIL and CFITSIO. These interfaces are currently
used by a number of tools, primarily in mission packages such as Swift,
Suzaku, and NuSTAR. Portability of the pre-compiled binaries
depends heavily on the version of Perl used to generate the binaries, and in
many cases users may find that there is a mismatch between their version of
Perl and the one we used.
Note that after installing a new version of Perl, you will need to redefine the LHEAPERL environment variable used by HEASoft in order for the pre-compiled binaries to work. The best way to do this is by re-configuring the binaries to use your new Perl as follows:
setenv PERL /path/to/your/new/perl cd heasoft-6.26/<platform>/BUILD_DIR/ rm config.cache ./configureIf you have any questions about the information above, please write to us at the FTOOLS help desk.
