Hi,
i want to install the cfitsio library to read compressed fits files in IDL 8.4 running on Ubuntu 14.04 64-bit version. Two programs need this library: READ_SDO as well as READFITS (only for *.fits.fz files for the latter program). I have followed the instructions as given at this link:
http://heasarc.gsfc.nasa.gov/fitsio/fpack/
The fun part is that while READ_SDO runs as expected, I get an error saying
<funpack: command not found>.
(Does it have something do with the shell in which the command is running? Because, while READ_SDO runs in tcsh, the READFITS error command is preceded by the name of the shell, which is either 'sh' or 'bash')
thanking in advance,
Anand.

Does the funpack command run at the command line (outside of IDL)?
READFITS() simply spawns to open a pipe to the funpack command:
spawn,'funpack -S ' + filename, unit=unit,/sh

I am not familiar with the package you are using but it looks like its first step is to uncompress a file and write it to a temporary directory. The program is then failing because it can't find the uncompressed file. First, does the temporary directory exist?
C:\Users\Home\AppData\Local\Temp
Is the file HMI20160107_235808_6173.fits being written to that directory?
Sometimes the problem is due to a space in the directory/file name. --Wayne
