Re: fresh checkout and compile

["Mark M. Ito" <marki@jlab.org>]

Ryan,

You are quite right; one should not have to struggle as you did.

This "feature" was introduced by me, I am sorry to say.  I made the 
switch to having event.xml be the authoritative file. Unfortunately, 
this introduces a two-level chicken and egg problem. Level 1: you need 
to build hddm-c on the programs side before you do a make on the 
libraries side in HDDM. And level 2: you need to do a make in the 
include directory on the libraries side in the include directory before 
you do the aforementioned make on the programs side. Suffice it to say 
the current make system was not designed to deal with an authoritative 
event.xml.

By the way, your solution is quite reasonable. Doing all this 
automatically is on my list. You just moved it to the top. Probably 
should have been there before.

I should say that I think both HDDM and HDDS should perhaps (in the 
future) be broken out of our standard tree and stand independently. They 
are really tools, and have no particular knowledge of GlueX or Hall D or 
any other particular geometry or data format. That way these tools could 
be built first (like we build ROOT and CERNLIB) and the GlueX-specific 
build items could go ahead and use them. So, for example, the hddm-c 
binary would exist before the GlueX build starts.
