[Developers] How to build admb source with mingw 64 - finally!

[Grandin, Chris]

Hi Arni,
  I agree with you - I think only developers need MSYS, and the users group should be able to use mingw-64 TDM. So we don't need to include msys with the installer and binary builds. I tried the rtools approach back when we were talking about it in the summer and couldn't get it to work, could you put together a howto for it so that we can all try? Then we will have two methods with which to compare.
Thanks!

Chris

Hi all,

Good to hear that the Windows build is working smoothly now. Your efforts 
are appreciated by everyone, including me.

In July, I built both 32 and 64 bit ADMB using the GCC compiler that comes 
with Rtools. At that point I suggested we use whatever GCC is in the most 
current Rtools distribution as our main compiler. This suggestion was 
based on (1) successful compilation, (2) letting the R people [Murdoch, 
Ripley] do the hard work of finding the best GCC compiler for Windows, (3) 
R will be around for many more years, and (4) many people already have 
Rtools installed and in their PATH. The Rtools GCC also comes with gdb and 
some other useful tools.

Rtools is considerably smaller and feels more native than MSYS. If I 
remember correctly, MSYS comes with some medium-size programs, such as a 
Perl interpreter.

Can someone summarize the main pros and cons of Rtools vs. MSYS for 
building ADMB?

I appreciate the usefulness of MSYS for developers, but isn't it a bit too 
large to fit inside the ADMB-IDE installer?

Arni
