Thanks for your reply. The background and present state of the
problem is this:
I have recompiled pygres 2.1 to use with postgresql 6.3.2-8. Trying
to use it results in:
---------------------------------
from pg import *
ImportError: /usr/lib/python1.5/lib-dynload/pgmodule.so: undefined
symbol: lo_creat
------------------------------------
I have the standard Debian 2.0 installation of postgresql and python
1.5.1. Previously I did not use debian packages on these programs
because the debian packages were not up to date on my 1.3.1 CD's.
All the libpq libraries are in the right places. I have used the following
makefile to compile pygres:
---------------------
#!/bin/make
CC=gcc
blddir=/usr/lib/python1.5/config# This dir includes the config.h file for
# the Debianized Python distribution.
srcdir=/usr/include/python1.5/ # Here is the Python include directory.
OPT= -O # This is the standard optimization flag.
INCLUDES= -I$(blddir) -I$(srcdir) -I/usr/include/postgresql \
-L/usr/lib # This line includes
# the specific pgsql
# directories which are
# needed.
DEFINES= -DHAVE_CONFIG_H # Tell the compiler that a config.h file exists.
CFLAGS= $(OPT) $(DEFINES) $(INCLUDES)
all: pgmodule.so
pgmodule.o: pgmodule.c
$(CC) $(CFLAGS) -c pgmodule.c
pgmodule.so: pgmodule.o
ld -G pgmodule.o \
-o pgmodule.so
-----------------------------------------
ldd /usr/lib/python1.5/lib-dynload/pgmodule.so
statically linked
Wayne suggested that I change the line beginning with pgmodule.so to
pgmodule.so: pgmodule.o
$(GCC) -shared -o pgmodule.so pgmodule.o -lpq
However, the compiler complained about a missing separator when I do that.
I then tried
pgmodule.so: pgmodule.o
ld -G -shared pgmodule.o \
-o pgmodule.so -lpq
It compiled successfully and the result of ldd was:
ldd /usr/lib/python1.5/lib-dynload/pgmodule.so
libpq.so.1 => /usr/lib/libpq.so.1 (0x4000a000)
libc.so.6 => /lib/libc.so.6 (0x40015000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)
When I tried to run it:
from pg import *
ImportError: /usr/lib/libpq.so.1: undefined symbol: crypt
At least I am having some progress.
Thanks for your interest.
Johann.
