Linux: directory change .../lib to .../lib64

From

Hello,

Below the top level directory (--prefix) the lib directory changed with
version 14.x now from .../lib to .../lib64:

ls -ld /usr/local/sisis-pap/pgsql-*/li*
drwxr-xr-x 1 root root 2754 19. Jul 09:58 /usr/local/sisis-pap/pgsql-13.3/lib
drwxr-xr-x 1 root root 1594 19. Okt 10:36 /usr/local/sisis-pap/pgsql-14.0/lib64
drwxr-xr-x 1 root root 2810 29. Nov 10:59 /usr/local/sisis-pap/pgsql-14.1/lib64

This would mean changes of LD_LIBRARY_PATH of our servers using the
PostgreSQL server with ESQL/C interface (libecpg.so.6). Why this change
was made? For a future 128-bit Linux?

I will see if I can overwrite this with:

./configure --prefix=/usr/local/sisis-pap/pgsql-14.1 \
            --libdir=/usr/local/sisis-pap/pgsql-14.1/lib ...

Btw: the help of ./configure says wrong things about the default:

./configure --help | egrep 'libdir=|prefix='
  --prefix=PREFIX         install architecture-independent files in PREFIX
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX for instance `--prefix=$HOME'.
  --libdir=DIR            object code libraries [EPREFIX/lib]

Thanks

You'd have to talk to the packager of whatever distribution you're using.
No such change was made in the core PG code: the configure script still
defaults to LIBDIR=EPREFIX/lib.

It's me who is the packager. I compiled from source and the used
configure run is:

#!/bin/sh

cd ~sisis/mpi-V73/postgresql-14.1 || exit

export LDFLAGS="-L/usr/local/sisis-pap/lib -L/usr/lib64"
export CFLAGS="-m64 -I/usr/local/sisis-pap/include"
export CPPFLAGS="-m64 -I/usr/local/sisis-pap/include"

./configure --prefix=/usr/local/sisis-pap/pgsql-14.1 \
        --enable-nls \
        --with-perl \
        --with-ldap \
        --with-pam \
        --with-openssl

echo now run \'make world\' and as root \'make install-world\'

And this brings the shared libs to  /usr/local/sisis-pap/pgsql-14.1/lib64

Thanks

From the file config.log:

...
configure:2687: loading site script /usr/share/site/x86_64-unknown-linux-gnu
| #!/bin/sh
| # Site script for configure. It is resourced via $CONFIG_SITE environment varaible.

| # If user did not specify libdir, guess the correct target:
| # Use lib64 for 64 bit bi-arch targets, keep the default for the rest.

...

Is bi-arch really still relevant in 2021 (almost 2022)?

Well, Autoconf's provision for site-local scripts is very ancient.
I say again that this isn't anything we've changed: either that
file wasn't there last time you did this, or its contents changed
underneath you.
