Hi tom, (erased your reply by accident :(
I asked about this yesterday but I don't need postgres.h for building PHP. I need it for writing a C function.
So do I just copy it manually from src/include/ ?

add -I/usr/local/pgsql/include and -L/usr/local/pgsql/lib

as appropriate in your makefile or compile script (or environment)
and they'll be picked up automatically.

Adjust the path to where your PostgreSQL installation is as necessary.

TIA,

Subject: postgres.h missing?

I can see in the source dir the include file postgres.h (src/include/postgres.h) but it doesn't exist under the installation dir (under include I only have postgres_ext.h and _fe.h).
Located a related article (http://faqchest.dynhost.com/prgm/pgsql-l/pgsql-01/pgsql-0104/pgsql-010404/pgsql01040314_23260.html) which implies that at least for the php build, postgres_fe.h should do just fine (even though the opening comments in postgres_fe.h suggest that postgres.h should be in the same dir and used instead)

Did I miss building something or should I use postgres_fe.h instead?

TIA,
thalis

That is not the issue but thanks anyway for the effort. The problem pertained:
$ gcc -fpic -c -I/usr/local/pgsql/include/ cfunc.c
In file included from cfunc.c:2:
/usr/local/pgsql/include/postgres.h:49: utils/elog.h: No such file or directory
/usr/local/pgsql/include/postgres.h:50: utils/palloc.h: No such file or directory

So I actually used the postgres.h file from the src directory to make it work.
$ gcc -fpic -c -I/usr/local/tmp/postgresql-7.1.2/src/include/ cfunc.c

What I'm missing is: did I mis-build something? How come the postgres.h and rest .h files weren't properly installed?

thanks,
thalis

Should I assume correctly that cfunc.c is something you wrote? If it is,
instead of including postgresql.h, try including libpq-fe.h as that's the
file that's installed. That should give you everything you need.

To do backend code development, you need to either add a -I pointing at
the source include tree, or do make install-all-headers.

If you are talking about client-side code, it probably shouldn't depend
on any of the backend-side headers.
