Laendro, The problem is that the file on your machine is apparently in DOS file format when it should be in unix file format. Specifically, each line in your file(s) has a LFCR at the end and it should only have a LF. Perhaps it was the way you got it out of the repository and/or somebody checked it in that way? An easy way to fix it with vim is to edit the file and do this: :se ff=unix :wq Paul From: h323plus-bounces@lists.packetizer.com [mailto:h323plus-bounces@lists.packetizer.com] On Behalf Of leandro.alvares@caixa.gov.br Sent: Thursday, January 28, 2010 5:52 PM To: h323plus@lists.packetizer.com Subject: [h323plus] h323plus configure bug?
