Package: libcfitsio2
Version: 2.510-1
Severity: normal
Tags: upstream patch
The libfitsio2 library does not work on arm and mipsel. I discovered this
from the buildd logs for the slcfitsio package:
http://buildd.debian.org/fetch.php?&pkg=slcfitsio&ver=0.3.2b-4&arch=arm&stamp=1132249413&file=log&as=raw
http://buildd.debian.org/fetch.php?&pkg=slcfitsio&ver=0.3.2b-4&arch=mipsel&stamp=1132283865&file=log&as=raw
The simple test program attached below fails on vaughan.debian.org (a
mipsel machine) with the following error message:
[EMAIL PROTECTED]:~$ ./test

Byteswapping is not being done correctly on this system.
Check the MACHINE and BYTESWAPPED definitions in fitsio2.h

The following patch to the upstream source fixes the problem on vaughan:

[Please, notice that I only tested the patch above on vaughan, a mipsel
machine. There is currently no arm machine available to Debian
developers.]
