Re: "undefined reference" error when compiling extension functions

I just finished doing a clean build with the same result. I have installed
everything to the defaults

(uninstall previously installed windows installation)
$ Configure --without-zlib
--with-includes=~/postgresql-8.0.2/include/port/win32/*
$ make install

When I try to complile the source for the extension after this I get the
same message as before. I'm going to hang up my hat for the day and give it
a run again tomorrow. Then I'll try and find out where libpostgres.a is and
see if I can add it to the search path with LDFLAGS and -I specified. Let me
know if you think of anything else.

I appreciate all the help. I'm not used to so many people being so willing
to help. Usually when I post a problem I'm having on "other" lists I get
either useless answers or none at all.

Thanks again,

Mark

It seems to be looking for libpostgres.a, which is created as part of a
standard build ... which takes me back to my earlier suggestion of doing
a full configure/make to give yourself the right enviroment to build
extensions.
