compiling postfix and mysql from source rpm fails

[Duncan noorman]

We are in the proces of setting up an email server using postfix
compiled with “DOVECOT“, “TLS“, “BDB“, “MySQL“, and “VDA”. SLES 10
provides postfix 2.2.9 and we need a versio > 2.3.0.

We are attemting to create a secure (smtps, pop3s, imaps) virtual user
email service on our power5 with SLES10.2 with encrypted passwords.

In an attemt to build from postifxi srpm
rpmbuild --rebuild --target=ppc64 postfix-2.3.2-12.6.src.rpm
we see:
/usr/bin/ld:warning: powerpc:common64 architecture of input file XXX
is incompatible with powerpc:common output

and /usr/src/packages/BUILD/postfix-2.3.2/src/global/dict_mysql.c:444:
undefined reference to `msg_info'

in an attempt to rectiffy the mysql problems we tried building mysql
from the srpm.. but this fails with the message
libstdc++.so: could not read symbols: File in wrong format

How can we build potfix > 2.3.0 with the needed support?

rpm has no support for telling gcc about the desired architecture.
SLES10 gcc defaults to 32bit powerpc-linux, but many configure scripts
look at the 'uname -m' output and think that 64bit powerpc64-linux code
will be created by gcc.
Please use 'powerpc32 rpmbuild --rebuild postfix-2.3.2-12.6.src.rpm' to
set the 'uname -m' output for subprocesses to 'ppc'.

Running all commands via 'powerpc32 commandd ...' will fix this.

To simplify that, run 'powerpc32 bash' to get a "32bit shell".
