Re: Build RPMs from git

[Ken Dreyer <kdreyer@redhat.com>]

Here's how I do it.

1. Git clone

2. ./do_autogen.sh

3. ./configure --without-radosgw --without-fuse --without-tcmalloc --without-libatomic-ops --without-libxfs 

4. # The "configure" step above creates a ceph.spec with the proper version number, which you can then copy:
   cp ceph.spec ~/rpmbuild/SPECS/

5. # The "configure" step above also creates a Makefile, so you can run "make dist-bzip2" to get a properly-versioned tarball:
   make dist-bzip2

6. # Now move the tarball in to place, along with the .patch file:
   rm ~/rpmbuild/SOURCES/*
   mv *.bz2 ~/rpmbuild/SOURCES/
   cp rpm/*.patch ~/rpmbuild/SOURCES/

7. # Build a source RPM:
   rpmbuild -bs ~/rpmbuild/SPECS/ceph.spec

8. # Lastly, rebuild that SRPM in mock:
   mock -r epel-7-x86_64 rebuild ~/rpmbuild/SRPMS/ceph-....src.rpm


This whole process needs to be improved :) We're moving towards getting rid of the ./configure operation in step #3 since that is only done in order to figure out the right version number for steps #4 and #5.

Also, the .patch file in step #6 could be implemented in some other way. We could use sed during %prep to make the changes, which would avoid using a .patch file. Or, since src/init-ceph.in is an autoconf template anyway, we could conditionalize this with autoconf to print "Default-Start: 2 3 4 5" and "Default-Stop: 0 1 6" on Debian, and leave the values blank on Red Hat.
