I am trying to install ArcSDE 10 for PostgreSQL in CentOS. I tried doing that but am stuck with same errors repeatedly and am thinking of giving one more shot from the scratch. I just want to make sure the versions/releases before I start over again. I am thinking of using CentOS 5.4 (for i686 architecture), PostgreSQL 8.3.8/8.4.1, PostGIS 1.4.0 and ArcSDE 10. Please let me know if I have to change any version/releases of any software.
