Building a 32-bit RPM on a 64-bit machine?
Hello again, I would like to be able to create a 32-bit RPM (with no 64-bit library dependencies) on a 64-bit machine. I have a 64-bit, SuSE development machine, and I would like to create an RPM on this 64-bit machine that will install 32-bit software on a 32-bit SuSE machine. Any ideas on the correct way for me to proceed? Thanks for any and all guidance! Joe P.S. Thanks very much Jeff for the answer to my Creating an RPM to install a daemon question. -- __ RPM Package Managerhttp://rpm5.org User Communication List rpm-users@rpm5.org

Is there some other command I should use rather than this external chkconfig program? If you want to use the fedora way to do packaging http://fedoraproject.org/wiki/Packaging/SysVInitScript https://fedoraproject.org/wiki/Packaging/ScriptletSnippets http://fedoraproject.org/wiki/Packaging/Guidelines the standard way is (example squid with some my comment) .. Requires(post): /sbin/chkconfig Requires(preun): /sbin/service /sbin/chkconfig Requires(postun): /sbin/service . .. %post /sbin/chkconfig --add squid %preun #last removal if [ $1 = 0 ] ; then service squid stop /dev/null 21 rm -f /var/log/squid/* /sbin/chkconfig --del squid fi %postun #restart the service if it was already running, in update only if [ $1 -ge 1 ] ; then service squid condrestart /dev/null 21 fi If you were curious of why there are if condition based on the number of package installed ($1) that it's because in update RPM performs the following sequence of actions (the install-before-remove sequence tipical of RPM) * Run%pre of new package * Install new files * Run% post of new package * Run% preun of old package * Delete any old files not overwritten by newer ones * Run% postun of old package best regards Thanks!

It depends if your package use autoconf,automake,libtool or not. BTW, the standard way is setarch i386 rpmbuild --target=i386 --rebuild pippo.src.rpm, or better use an automated tool that do this as mock, for examplehttp://fedoraproject.org/wiki/Projects/Mock. http://fedoraproject.org/wiki/Projects/Mock Regards On Fri, Oct 29, 2010 at 3:07 PM, Joe Flowers joe.flow...@nofreewill.comwrote: Hello again, I would like to be able to create a 32-bit RPM (with no 64-bit library dependencies) on a 64-bit machine.

SuSE does multilib differently than RedHat afaik. IIRC, there are 3 products 1) ELF32 only 2) ELF64 only 3) multilib. What's missing is all the needed other persuasion packages on 1) and 2). So what you want is no different than setting up a cross-compiler, or other wise setting up host - target infrastucture. But its rather easy to set up whatever you need with an install into a chroot(2). That does need root access to execute chrott(2). 73 de Jeff __ RPM Package Managerhttp://rpm5.org User Communication List rpm-users@rpm5.org
