The problem is resolved. I just edited the Makefile.am directly and then use automake. From: gladiatorcn@hotmail.com To: monetdb-developers@lists.sourceforge.net Subject: autogen.py Date: Mon, 25 May 2009 17:52:00 +0000 Hi, I am new to MonetDB development. I add some source files to MonetDB/MonetDB/src/gdk, which rely on the external libraries. When I try to modify Makefile.am in order to add the relevant link information. It says that it was generated by autogen.py. To be honest, I do not know autogen.py and I could not find any useful information from Google. Could you guys give a little hint please?
