The RPM spec file libvirt-cim.spec from the most recent snapshot includes these two build constraints: BuildRequires: libcmpiutil-devel BuildConflicts: sblim-cmpi-devel The RPM spec file libcmpiutil.spec from the most recent snapshot includes this constraint: BuildRequires: sblim-cmpi-devel With RPM 4.4.2 on RH5.2, this results in it being impossible to generate a libvirt-cim RPM; the build dependency libcmpiutil has on sblim-cmpi-devel is being retained as a runtime dependency. This may be a result of a mistake or mistaken assumption on my part, but it may also be an error in one or both spec files. Below is a lightly edited log of the results of trying to build a libvirt-cim RPM from the current snapshots. - [tyler@tyler-rhel32-vm libvirt-cim-0.5]$ sudo rpmbuild -ba libvirt-cim.spec Password: error: Failed build dependencies: libcmpiutil-devel is needed by libvirt-cim-0.5-1.i386 [tyler@tyler-rhel32-vm libcmpiutil-0.1]$ sudo rpmbuild -ba libcmpiutil.spec error: Failed build dependencies: sblim-cmpi-devel is needed by libcmpiutil-0.1-1.i386 [tyler@tyler-rhel32-vm Server]$ sudo rpm -ivh sblim-cmpi-devel-1.0.4-31.el5.i386.rpm warning: sblim-cmpi-devel-1.0.4-31.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186 Preparing... ########################################### [100%] 1:sblim-cmpi-devel ########################################### [100%] [tyler@tyler-rhel32-vm libcmpiutil-0.1]$ sudo rpmbuild -ba libcmpiutil.spec Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.17372 ... ...
