Re: How to write make rules for shared library and

Hi,I have written a patch to PostGreSQL to produce shared 
library (dylib) or plug-ins in Mac OS X. I have tested it in version 
7.3 through version 7.3.2 and worked fine with pgaccess too. 
Unfortunately I have no idea how to post it. Can you help me?
