Hello Mohammed,

I downloaded the file you linked to and tried to build it, but there are 
several other files that it refers to.  I did manage to build the manual 
with the indices after I had edited the source to remove references to all 
the images and some of the included files.

I notice that it is the latest version of texinfo.tex that is being 
used.  I had never uploaded that version to ftp.gnu.org; I expect 
somebody has got the file directly from the git repository.  In any 
case, it is useful that you are testing it.

It could be related to the change to use @ as the escape character in 
the index files.  Could you try running "texindex gnuastro.fn" and 
"texindex gnuastro.cp" and having a look at the contents of
gnuastro.cps and gnuastro.fns afterwards?  Then you could try running 
"pdfetex gnuastro.texi" to see if the PDF file is created with the 
indices.

Running "texi2pdf --verbose gnuastro.texi" might give more information 
about why texindex is not being run or not being run properly.
