[postgis-users] PostGIS 2.0 instalation problem

[wobo]

Hi all,

I'm a newbie student, just finished reading 'Postgis in action' and now
trying to get PostGIS2.0 up and running for the first time. Now I'm
suffering a similar problem in setup like the one mentioned earlier in this
thread.

Using Windows XP SP3 I was able to install the latest PostgreSQl 9.1.3
stable version. Trying to install PostGIS 2.0 with the one-click installer
fails during makepostgisdb.bat (CREATE EXTENSION postgis;): 
ERROR:  could not load library "C:/Program
Files/PostgreSQL/9.1/lib/postgis-2.0.dll": unknown error 998

I tried several approaches (restarting, copying by hand, renaming, etc) as
mentioned in similar other threads but nothing succeeded so far. All the
important files seem to be in the right place. It seemed some needed
dependencies first were missing (LIBGEOS, LIBXML2-2, POSTGRES, LIBPROJ-0) so
I added the PGBIN to the environment variable. 

After restart Dependency Walker now finds these mentioned files but there
are still dependency errors on IESHIMS.dll and WER.dll. I read that these
are unnecessary/unused in Windows Xp. Does this imply that it is impossible
to install PostGIS2.0 on Windows XP? Before there were a lot of errors but
now the pg_log file only throws the "could not load library postgis-2.0"
error line like:

2012-05-02 00:25:05 CEST LOG:  database system was shut down at 2012-05-01
23:26:44 CEST
2012-05-02 00:25:06 CEST LOG:  database system is ready to accept

2012-05-02 00:25:30 CEST ERROR:  could not load library "C:/Program

2012-05-02 00:25:30 CEST STATEMENT:  CREATE EXTENSION postgis;
2012-05-02 00:25:30 CEST ERROR:  required extension "postgis" is not
installed
2012-05-02 00:25:30 CEST STATEMENT:  CREATE EXTENSION postgis_topology;

I have no clue how to proceed from here... Any suggestions? 

Thanks in advance,
Wouter
