<P><FONT SIZE=2>Hi Arni,<BR>
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.<BR>
Thanks!<BR>

Hi all,<BR>
<BR>
Good to hear that the Windows build is working smoothly now. Your efforts<BR>
are appreciated by everyone, including me.<BR>
<BR>
In July, I built both 32 and 64 bit ADMB using the GCC compiler that comes<BR>
with Rtools. At that point I suggested we use whatever GCC is in the most<BR>
current Rtools distribution as our main compiler. This suggestion was<BR>
based on (1) successful compilation, (2) letting the R people [Murdoch,<BR>
Ripley] do the hard work of finding the best GCC compiler for Windows, (3)<BR>
R will be around for many more years, and (4) many people already have<BR>
Rtools installed and in their PATH. The Rtools GCC also comes with gdb and<BR>
some other useful tools.<BR>
<BR>
Rtools is considerably smaller and feels more native than MSYS. If I<BR>
remember correctly, MSYS comes with some medium-size programs, such as a<BR>
Perl interpreter.<BR>
<BR>
Can someone summarize the main pros and cons of Rtools vs. MSYS for<BR>
building ADMB?<BR>
<BR>
I appreciate the usefulness of MSYS for developers, but isn't it a bit too<BR>
large to fit inside the ADMB-IDE installer?<BR>
