[geos-devel] geos compilation problems

[Nicole Faust]

Hi group!

I have inastalled PostgreSQL (version 7.4.5) and want to install PostGIS
(version 0.9.0).
But PostGIS needs the geos library. So I downloaded the geos source-files
and started to compile it.

(The versions of PostgreSQL and PostGIS are compatible with the downloaded
geos version.
The directory with the source code is:
"/home/n_faust/software/software-source/geos-2.0.1/".
The directory for the installation of geos is:
"/home/n_faust/software/software/geos-2.0.1/".
And the OS of the computer where I would geos install is Sun Solaris version 5.9.)

First I got the following error message during compilation:
(I don't know the exact error message that the make command had shown.)

IsValidOp.loT    no such file or directory

So I changed the file name
"/home/n_faust/software/software-source/geos-2.0.1/source/geom/IsValidOp.loT"
to
"/home/n_faust/software/software-source/geos-2.0.1/source/geom/IsValidOp.lo"
and started compilation again. Now it worked... but only until the
following error message occured:

Can anyone help me, please?
Thank you in advance!
