[postgis-users] can't find lwlgeom

[Chris mollis]

Hi Mark-

Thanks for responding to this issue.  I was able to get around this 
issue by modifying the lwpostgis.sql file and replacing the $libdir var 
with the fully qualified path name to the shared object.  I ran all of 
the tests successfully.  I guess this proves that the $libdir variable 
isn't being set correctly with postgresql, even though PG_CONFIG reports 
it to be set (note I stopped and restart the server a few times during 
this process).   I believe there is a function exported by postgresql db 
that allows me to set this variable, but I haven't tried it.  Anyway, 
seems to be working now..

thanks

Chris
