Hi team I might need a bit of help, I am trying to build an STX ISO, I am failing at the step : [builder@5f9b406601e6 cgcs-root]$ build-pkgs kernel/kernel-modules/drbd/rpmbuild [0/1856] 17:54:11 Wrote: /localdisk/loadbuild/builder/starlingx/rt/rpmbuild/SOURCES/drbd-kernel -rt/srpm_input.md5 17:54:11 SRPM build not required for '/localdisk/designer/builder/starlingx/cgcs-root/ stx/stx-integ/kernel/kernel-modules/drbd' 17:54:11 ===== Build complete for 'drbd-kernel-rt' ===== 17:54:11 17:54:11 17:54:11 Auditing for obsolete srpms 17:54:12 Auditing for obsolete srpms Phase 2 17:54:12 Delete /localdisk/loadbuild/builder/starlingx/rt/tmp-builder-build-srpms-seri al-audit-X5LJ7z 17:54:12 Auditing for obsolete srpms done 17:54:12 ==== Update repodata ===== 17:54:12 Directory walk started 17:54:12 Directory walk done - 13 packages 17:54:12 Temporary output repo path: /localdisk/loadbuild/builder/starlingx/rt/rpmbuil d/SRPMS/.repodata/ 17:54:12 Preparing sqlite DBs 17:54:12 Pool started (with 5 workers) 17:54:12 Pool finished 17:54:12 ==== Update repodata complete ===== 17:54:12 17:54:12 No packages required a rebuild ######## Mon Jan 28 17:54:12 UTC 2019: build-srpm-serial --rt was successful ######## Mon Jan 28 17:54:12 UTC 2019: Launching build-rpms-serial --rt /localdisk/designer/builder/starlingx/cgcs-root/build-tools/build-rpms-serial --rt FORMAL_BUILD=0 modify-build-cfg /localdisk/loadbuild/builder/starlingx/rt/builder-starlingx-tis-r5-pi ke-rt.cfg make: all ALL=1 17:54:14 build-rpms-serial --rt 17:54:14 ALL=1 17:54:14 Find the list of packages we must compile 17:54:14 mktemp: failed to create directory via template ‘/localdisk/loadbuild/builder /starlingx/rt/tmp/builder-build-rpms-serial-need-build-XXXXXX’: No such file or direct ory 17:54:14 Failed to create temp directory under /localdisk/loadbuild/builder/starlingx/ rt/tmp ######## Mon Jan 28 17:54:14 UTC 2019: build-rpm-serial --rt failed with rc=1 Mon Jan 28 17:54:14 UTC 2019: build-rpm-serial --rt failed with rc=1 And because of this error then I get: [builder@5f9b406601e6 cgcs-root]$ build-iso 18:04:37 Debug: Packages still unresolved: 18:04:37 18:04:40 Could not resolve packages: kernel-rt kernel-rt-kvm kernel-rt-tools kmod-drbd-rt kmod-e1000e-rt kmod-i40e-rt kmod-integrity-rt kmod-ixgbe-rt kmod-tpm-rt mlnx-ofa_kernel-rt-modules qat17-rt 18:04:40 Error -- could not install all explicitly listed packages 18:04:40 Could not install dependencies Any clue how to address this issue All the other steps were addressed, with the minor bug that i had to download few tar balls from CENGN manually I am following a mix and match of 3 documentation to compile the ISO image: https://docs.starlingx.io/developer_guide/index.html http://git.openstack.org/cgit/openstack/stx-tools/tree/README.rst https://git.openstack.org/cgit/openstack/stx-docs/tree/doc/source/developer_... It might be a good idea to just create one documentation point easy to automate ( and provide the script ) Thanks a lot to Abraham and Hayde for addressing my questions on building the STX image Regards Victor Rodriguez
