[Koha-translate] Problems with tmpl_process3.pl ?

Hi to all, there are problems with the script tmpl_process3.pl ? I have finished the italian translation and I want to check the situation. So I checked the .po files with the last updated templates. No problem for Opac. But for staff I see: $>./tmpl_process3.pl update -i ../../koha-tmpl/intranet-tmpl/prog/en/ -s po/it-IT-i-staff-t-prog-v-3000000.po -r Charset in/out: UTF-8 at ./tmpl_process3.pl line 257. tmpl_process3.pl: ERROR: Text extraction failed: ./xgettext.pl: Inappropriate ioctl for device tmpl_process3.pl: ERROR: Will not run msgmerge Update FAILED. The update fails and I don't know why. Bye Zeno Tajoli CILEA - Segrate (MI) tajoliAT_SPAM_no_prendiATcilea.it (Indirizzo mascherato anti-spam; sostituisci quanto tra AT con @)
