Re: xgettext output nothing

You are right:
$ xgettext hello.c --force-po
generates this empty messages.po file:
---

The problem is I would like a not empty file :-)
I thought xgettext read the input file and generates the corresponding .po 
output file.
In hello.c (the input file) I have, for exemple, the line 109:
printf (_("hello, world\n"));
So I would like xgettext generates an output file corresponding to this entry.

How to generate a not empty .po file with xgettext?

If you want to output a PO file, even when it will be virtually empty, use the
option "--force-po".

The relevant info is in the "xgettext --help"'s output and in this manual page:
<http://www.gnu.org/software/gettext/manual/html_node/xgettext-Invocation.html>

> The source is available here:
> http://ftp.gnu.org/gnu/hello/hello-2.6.tar.xz

I think you should also take a look at the value of XGETTEXT_OPTIONS in the file
po/Makevars in that tarball.
