How to create RPM for 32-bit arch from a 64-bit arch server?

Question

Our production server is running CentOS5 64-bit arch.

Because there are no RPM available currently for SQLite latest version (v3.7.3), I created RPM using rpmbuild the very first time by following the instructions given here. I was able to successfully create RPM for 64-bit (x86_64) architecture. But am not able to create RPM for 32-bit (i386) architecture. It failed with the following errors:

error: Bad exit status from /var/tmp/rpm-tmp.73141 (%build)


RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.73141 (%build)

This is the command I called: rpmbuild --target i386 -ba sqlite.spec

My question is, how do I create RPM for 32-bit arch from a 64-bit arch server?

Solution 1

mock -r fedora-14-i386 --rebuild foo.srpm

Solution 2

mock will do a x86 build on a x86-64 system when you tell it to use a 32-bit root.

Solution 3

Install missing 32bit lib:

$ sudo yum install glibc-devel.i386

@Ignacio: Since rpmbuild is very new for me, I couldn't able to understand your comment. Can you explain/expand it little bit?

[Ignacio Vazquez-Abrams]

rpmbuild -bs sqlite.spec ; yum install mock ; mock .... path/to/sqlite....src.rpm fedoraproject.org/wiki/Projects/Mock

[Gnanam]

@Ignacio: So, in general, 32-bit arch RPM cannot be created from a server running 64-bit arch, without having mock installed?

[Ignacio Vazquez-Abrams]

Well... you can, but then you have to install 32-bit development tools and invoke it via setarch. It's much easier to just throw it at mock.

@Gnanam Mock also uses a cleanly built chroot environment to build your RPMs, so it doesn't accidentally pull in artifacts from the server it's being built on which might result in a build that differs from that you would get on a freshly installed server. I wouldn't build RPMs for production with anything else.
