Subject: Newbie: issues developing a new extension
From: camauz@yahoo.com (Christian Ferrari)

Dear all,=0AI'm asking your help because I'm not able to solve an issue pro=
bably related to some foolish mistake I have not yet discovered.=0AI'm tryi=
ng to develop an experimental extension to interface LIXA library (http:/li=
xa.sourceforge.net/).=0A=0AI have created the basic stuff (config.m4, lixa.=
