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

[Grandin, Chris]

Thanks Wade,
  I also wanted to add that the method Wade and I have been using there are no further changes to the building procedure required, Johnoel has worked hard at getting it stable and I think if we avoid needing flags for building in 64 bit and just rely on the build chain in place on each persons' machine it would be much simpler. Does rtools work like this or does its compiler need 64-bit build flags?

Cheers
Chris

Hi Arni,

I've never used Rtools for building so can't comment on pros/cons.  It sounds like you've worked this out in an easier fashion so I'd be interested in experimenting if you could send a brief overview of how one would build the ADMB source using Rtools.

I work in Eclipse and remember having issues getting the Eclipse CDT working with the Rtools GCC a few years back.  Hence I switched to my current configuration (TDM, msys) mainly because it was the only way I could get 64bit Eclipse playing well on 64bit XP, and it worked for ADMB too.  Everything may work fine now since 64bit support in Windows is progressing a bit since XP. 

Wade

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
