RM programs depend at a minimum on Qt and MySQL.  Similar to the executables, they're stored under a directory with a name of the form  /nfs/farm/g/glast/u35/grits-externals/some-dir where some-dir is in the platform's sysname list.  For rhel7 this will be amd64_rhel70

I downloaded source for Qt open source version 4.8.6, unpacked and configured like this:

./configure -static -qt-sql-mysql --prefix=/nfs/farm/g/glast/u35/grits-externals/amd64-rhel70 -nomake examples -nomake demos -nomake translations -nomake tools

Tom's notes say to install the Spirit miniboost package (it's include files only), but it is not installed as such for rhel6.  I can find no evidence in source code, Makefiles or Qt .pro files that it's used.

They also mention stx-exparser.   That is used, but apparently only by workflow, not by releaseManager.   And its README explains that it depends on the Spirit miniboost package!  But only at build time. RM itself doesn't need it.  On rhel6 all the boost files needed can be found under /usr/include/boost.   That's not currrently the case for rhel7.

Possible short-cut

It may be that we can get by with the rhel6 binaries of RM programs and externals to begin with. (The rhel5 build of GoGui, another Qt-based program, is perfectly usable on rhel6 and comes up with no complaints on rhel7.)  Ultimately we should have a native rhel7 build, but if the rhel6 binaries are usable the db updates and Jenkins interface could be tested much more quickly.
