Hi Steve,
There have been many problems with the gamma function between systems.
Everybody's machine seems to support something different. It also seems
like the only way to support everybody at the moment would be a hack or
to maintain our own gamma function, which would come from a numerical
recipes book.
In the mean time, were you able to compile before the latest commit? If
so, I would revert RATSimpleDAQ.cc to the previous version, which just
used tgamma, not lgamma for the time being. Run:
$ cvs update -r 1.6 src/RATSimpleDAQ.cc
-Chris
