[postgis-devel] PostgreSQL 7.5 and PostGIS 0.8.1 or cvs

[Craig Miller]

I am getting closer.  I am only having linker errors now.

In case anyone else wants to know what I did.

After getting the latest from CVS I first applied the changes to the
Makefile and postgis.h that others have already described.

I then tried to compile and received an error about using index and rindex
in postgis_inout.c.  It turns out that these are non-ANSI versions of strchr
and strrchr respectivley. msvcrt.dll exports only the ANSI names, so I
changed the references to the non-ANSI names to strchr and strrchr
respectively.  E.g. they now read:
	first_paren= strchr (str,'(');
	last_paren = strrchr(str,')');

So now I am left with the following linker errors.  To be frank, I have not
used Make, autoconf, automake, etc in many years (too much Visual C++ and
Java lateley) so I am having trouble figuring out how to correct this
"correctly".  If anyone has info on the correct way to fix this, that would
be appreciated.  If not, I have my GNU Autoconf, automak, and libtool book
cracked open and should be able to get it figured out before too long.

Here is the link error I still have left.

You are compiling against pg74, not 75 (-DUSE_VERSION=74).
To detect pgsql version, postgis Makefile goes:

                        ifneq ($(findstring 7.4,$(VERSION)),)
                                USE_VERSION=74
                        else
                                USE_VERSION=75
                        endif

What does your postgres snapshot's global Makefile use as $(VERSION) ?
