Re: [help-gnuastro] GNU Astro configure error - missing WCSLIB component

[Mohammad Akhlaghi]

No problem, I am happy we are making good progress.

You need to link with the proper CFITSIO library also, similar to 
WCSLIB, with this configure command:

./configure --prefix=/packages/gnuastro/0.5
LDFLAGS="-L/packages/wcslib/5.18/lib -L/packages/cfitsio/3.410/lib"
CPPFLAGS="-I/packages/wcslib/5.18/include -I/packages/cfitsio/3.410/include"

`fffree' is a function in CFITSIO. Since you now include the CFITSIO 
headers (with `-I/packages/cfitsio/3.410/include'), it was able to 
compile the Gnuastro's Arithmetic program (which is the program causing 
the crash). But when it wanted to link it with the CFITSIO library, it 
couldn't. The new `-L/packages/cfitsio/3.410/lib' linker option will fix 
the problem.

By the way, if your HPC system has more than 8 threads, you can use a 
larger number in `make -jN' (N being any number larger than 1) to speed 
up the build. In Make, `j' stands for "job", it means the maximum number 
of jobs to run in parallel at any moment.

Hopefully there shouldn't be any more problems.

Cheers,
