problem with xgettext

[Michel Boaventura]

Hello,

Now when I try to compile the master branch of pspp, I'm getting this
error:
xgettext: no input file given
Try `xgettext --help' for more information.

The command which gives the error is:

xgettext --directory=../pspp --copyright-holder="Free Software
Foundation, Inc." --package-name=pspp --package-version=0.7.4
address@hidden --add-comments='TRANSLATORS:' -j
--language=glade -o po/pspp.pot

I don't know if this matter, but here is the output of xgettext
--version:

xgettext (GNU gettext-tools) 0.17
