correct way of linking postgresql from iexpress (32 vs. 64bit)?

[Florian Heigl (new acc)]

Hi,

I had the following command fail during a software build:

/opt/gcc343/pa20_64/bin/g++ -O -L../lib -L../cats -L../findlib -o bscan bscan.o block.o device.o dev.o label.o ansi_label.o dvd.o ebcdic.o autochanger.o acquire.o mount.o record.o match_bsr.o parse_bsr.o reserve.o butil.o read_record.o stored_conf.o spool.o wait.o \
-lsql -L/opt/iexpress/postgresql/lib -lpq -lz -lfind -lbac -lm -lpthread -lgen
/opt/iexpress/postgresql/lib/libpq.sl: file not recognized: File format not recognized
collect2: ld returned 1 exit status


my environment is set as follows:
export PATH=/opt/gcc343/pa20_64/bin:/usr/local/bin:$PATH
export MAKE=gmake
export CC=gcc

Upon checking I could see that /opt/iexpress/postgresql/lib/libpq.sl is a 32bit PA-RISC 1.0 library, while /opt/iexpress/postgresql/lib/pa20_64/libpq.sl is the 64bit version I need.

As my software is usually only supplied a base path (i.e. /opt/iexpress/mysql), I'm really curious to what the right way[tm] is in such a situation?

If I hadn't set out to resolve all issues on the way, I'd just move everything from lib/pa20_64/ to lib :)

Can anyone share some insight with me?

looks like this problem is because of the

"-L /opt/iexpress/postgresql/lib"

in the link line. you simply have to change it to

"-L /opt/iexpress/postgresql/lib/pa20_64"

if you still have problems. look at all the other paths specified with "-L" and make sure that they point to directories containing the appropriate versions of libraries.

And how can I achieve the same before running ./configure ?
Is this an LDFLAG?

[ranganath ramachandra]

well i'm not sure about the configure for this particular package. check if "configure --help" lists any option that configures the whole thing for 64bit.

Hello,

Yes, you can export LDFLAGS and SHLIB_PATH before starting ./configure..

Other way is, editing the corresponding makefile to add /opt/iexpress/postgresql/lib/pa20_64
