Re: Gnuastro 0.16.184 released

[Mohammad Akhlaghi]

Hi Aaron,

Thanks for sharing this experience. Indeed, some new features come along 
on the dependencies. To allow Gnuastro's users to benefit from them, we 
need to add configure-time checks for those users that don't still have 
them. To encourage updating the dependencies and benefiting from those 
features, I have put those warnings ;-).

About this particular CFITSIO problem, no! I haven't seen it before. 
From the other outputs of the configure script, I see that at least the 
C compiler comes from Anaconda3. Maybe the environment of Anaconda is 
conflicting with your Ubuntu's in some way that is not letting CFITSIO's 
configure script find the zlib library?

But what was your previous version of CFITSIO and corresponding warning 
in Gnuastro's configure? Probably its not too critical, so you can 
continue using that version of CFITSIO to build Gnuastro and try out the 
extended-PSF tutorial for now (until the cause of the latest CFITSIO 
build is found and solved)?

Please share any feedback about the extended-PSF tutorial and script ;-).

You get the latest version of the Gnuastro tarball and book in [3] and 
[4] (both have a couple of minor edits and bug fixes since version 
0.16.184). Hopefully in a few days we'll release version 0.17, and with 
such feedback it will get as complete and useful as possible.

Cheers,
Mohammad
