rpm

This page describes how to alter rpm so that it produces CPU-optimized binaries. You will also need a modified redhat-rpm-config package and, if you use the Intel compiler, the intel-extras package.

rpm-4.4.2.3-2

SRPMS

Start with the upstream rpm source RPM.

SOURCES

Add the following patches.

rpm-4.4.2.3-64bit.patch

This is a minor patch for 64-bit platforms which makes some debug statements print correctly.

rpm-4.4.2.3-intel.patch

This patch makes sure that the following architecture names exist and that relevant compiler optimization flags are chosen: pentium3, pentium4, pentiumm, prescott, nocona,and core2.

rpm-4.4.2.3-warning.patch

This patch eliminates a boatload of C compiler warnings, so that I have some hope of being able to dig through the remaining ones to find real problems.

rpm-4.4.2.3-doxygen.patch

This patch updates the Doxyfile for use with doxygen 1.5.5 (the unpatched Doxyfile is for doxygen 1.3.5).

SPECS

Finally, apply rpm.spec.patch to the spec file and build.
