[ADMB Users] windows version of admb

[Jim Ianelli]

This installation worked well (the Rtools28.exe option) and was seamless
with the link that Dave provided below.  Thanks for that. 

My initial impression is that the compile-time is considerably slower than
the Borland compiler (old version 5.2) .  Runtime seems is improved
considerable (all within windows vista 32bit).  The Borland compiled code
for a basic assessment model took 39 seconds while the gcc compiled version
took only 25 seconds(no screen IO, I used the redirect ">NUL").  The same
model compiled in "safe" admb mode using the gcc compiler took 33 seconds.

Regarding the distribution of CPU load over the 2 processors was the same in
both cases (appearing to load one by about 1/3 and the other by about 2/3
capacity).

So it seems that using admb with the Borland compiler for development has
advantages (fast compile times, workable debugger) but for execution, the
gcc has clear advantages.  

I would like to open the discussion of debuggers.  I notice that the rtools
distribution doesn't seem to include the gdb tools or maybe I'm missing
what's commonly used.  Have folks that use MSVS C++ had luck configuring the
debugger to work well?

 
Cheers,
Jim
