[postgis-devel] RE: PostGIS compilation with Cygwin

Regina,

I get an ld with postgres issue, probably because it was built with cygwin?

ld: cannot find -lpostgres

More detailed compilation error is below.

Rimma, 

I'm not sure if building on Cygwin is still being tested with postgis so its
kind of hard to tell what kind of strange errors you would be getting.

Have you tried compiling with MinGW.  I think that's what most Windows
developers are using to compile Postgis.  That's what I usually use but its
been a while since I've done that myself.  I haven't tried Ming on my
windows vista laptop, so I'm not sure if there are any issues with running
that on Vista.

Sorry I'm not of much help.

Regina

Hi Regina,

No on the opposite, I am running PostgreSQL on Windows Vista.

The reason I use cygwin is because that's how my PostgreSQL was

setup (to be built with cygwin).

When I issue a 'make' for PostGIS, I get a lot of undefined statements

(something has to do with loader not seeing libpostgres.a).
