Re: warning _GL_ATTRIBUTE_SPEC_PRINTF_SYSTEM

[Mohammad Akhlaghi]

Thanks a lot for the check Bruno,

Did you see the message I sent a few hours ago (forwarded message 
below)? I was able to track down the Gnulib commit causing this issue.

To answer your questions: there isn't any 'stdio.h' in either of 
'/dev/shm/gnuastro-0.13.58-dad9/lib' or '/src/dir/gnuastro/lib'.

Thanks for reporting the problems with bootstrapping:

About LaTeX dependency in the boostrapping phase: its because some of 
the figures of the Gnuastro manual (like those in [1] or [2]) are 
created by LaTeX at this phase.

In the version controlled source of Gnuastro, we only keep the 
hand-written LaTeX source of these figures. But these figures are 
necessary for a normal build of the tarball (since they are mentioned in 
the Texinfo source). If we building them during the building of the 
documentation, then users will be forced to have LaTeX and its necessary 
packages to build Gnuastro. But if we do it during bootstrapping, only 
the developers need to have it.

Generally, all the bootstrapping dependencies of Gnuastro are documented 
in [3], which includes the list of necessary LaTeX packages. Gnuastro's 
mandatory dependencies are also listed in [4]. But to simplify the 
installation of the dependencies, we have added the commands to install 
them with some common package managers in [5]

Thanks a lot,
Mohammad

I found the Gnulib commit causing the problem:

387d654cabd7bc1594b1fc8d195cd9b66f820296
or
http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=387d654cabd7b

Gnuastro (on Commit c70f16c8f13c) builds with no warnings when 
bootstrapped with the previous Gnulib commit (cb432e7d6144). But on this 
Gnulib commit (387d654cabd) I get these warnings.

Since nothing has changed in Gnuastro, I guess the problem lies in this 
commit of Gnulib. Please let me know if I need to check anything else.

Thanks again for all the great work on Gnulib,
Cheers,
Mohammad
