What Works
* There is a script, offlineObf-win.py, which will take as input a CMT-style obf external and create a reorganized one which SCons can understand.
* One can check out GlastRelease-scons and run scons with a null target
scons --with-GLAST-EXT=%GLAST_EXT% --vc7 NoTarget
or use GoGui to do the same thing and, if your external libraries are up to date, it will succeed.
* Some packages build successfully and their test programs run successfully - all or nearly all of ScienceTools and some of GlastRelease
* GlastSvc can be built and its test program runs successfully as long as it's not built debug. Probably other Gaudi packages which don't depend on too much else exhibit the same behavior.
