Re: [bug-gnuastro] [info-gnuastro] Gnuastro 0.8 released

Hi David,

Thanks a lot for the complete information on the configuration problem.

Just one question: by making "a copy in /usr/local", do you mean that 
you configured CFITSIO with `--prefix=/usr/local" (so it is installed 
there), like the example in the Gnuastro book (link below)? Or did you 
manually copy the files/directory under that folder?

https://www.gnu.org/software/gnuastro/manual/html_node/CFITSIO.html

I have described the situation in a little more detail in the P.S.

On a sidenote, if you use Homebrew (a package manager for mac OS 
systems), you can easily install all the necessary dependencies with the 
respective command given under "brew (macOS)" in Section 3.1.4 of 
Gnuastro's book:

https://www.gnu.org/software/gnuastro/manual/html_node/Dependencies-from-package-managers.html

I hope this helps,
Cheers,
Mohammad

P.S.
Ideally (unless there is some special conflict which must be avoided), 
it is recommended that all software built from source (CFITSIO in this 
case) are installed in one place (the standard place/prefix to install 
them is `/usr/local').

But just note that when you configure with `--prefix=/usr/local', the 
final installed files are distributed in various subdirectories of it: 
libraries go under `/usr/local/lib', their headers go under 
`/usr/local/include' and programs go in `/usr/local/bin'.

Since the configure script found GSL and WCSLIB (which I presume you 
also built from source also), maybe good check would be to make sure 
that CFITSIO is installed in the the same directory as them.

For example, if you followed a standard build for GSL or WCSLIB (didn't 
change their `--prefix' at configure time), try running "ls 
/usr/local/lib" now (before fixing the problem). You will see several 
files named `libwcs' or `libgsl' (with different suffixes), but probably 
you won't find `libcfitsio'. If this is the case, and you configure 
CFITSIO with the steps given in the first link above, the problem will 
be solved.
