(sorry if you get this twice, but the email kept getting 'deffered'
because of a bad hello or something last night)
I try to statically link the testpq.c program via:
gcc -o testpq -lpq -static testpq.c
and get the following error:
[erecio@moz postgres]$ gcc -o testpq -static -lpq testpq.c
/tmp/ccIp5I09.o: In function `exit_nicely':
/tmp/ccIp5I09.o(.text+0xd): undefined reference to `PQfinish'

<MORE OF THE SAME>

While dynamically linking it works fine:
$ gcc -o testpq -lpq testpq.c
$ ldd testpq

libpq.a is in /usr/lib, but it's only about 93k. For the object files
that seems alot. I need to statically link the library because I am
going to be using a custom program in an embedded device where none of
the above libraries mentioned in the ldd works. All the the programs
statically link fine, except for libpq. I am using the redhat 7.3 rpms.

Several points to follow up on: ./configure && make && make install on
slackware 8.1 also did not produce a libpq.a file which I can use for
static linking. Tried (from postgresql src dir):
-- Cmd Line
ar r libpq.a `find /usr/local/src/postgresql-7.2.2/src |grep -v main.o`
ranlib libpq.a
--
And no go... can anyone tell me how to create a static library? Or which
object files to copy from postgresql source code to be able to link them
with testpg.c (note testpg.c can be found in the documentation for
postgresql - my program is significantly smaller and uses less postgress
calls.)
-- Clarification
ALso above, i meant, libpq.a seemed like too little, but it was 3am :)

YOU ROCK!

I've been away from C for too long... QT has pampered me and PHP has
made me lazy. Java well... has made me take everything for granted. :)
Hopefully this list is archived so someone else doesn't make that same
'oops'. Thanks a lot.
