True, this is what we do currently on COIN.  But usually the Windows 
unpackers don't have a problem to handles those .tar.gz files either.  If 
you have problems with it, you can send a suggestion to the coin-discuss 
mailing list.

And, yes, I for my part prefer to work on Linux.  But I'm still trying to 
keep the developer studio files somewhat running.  However, I have only 
one set of compilers, which probably by now are a little old, so I can't 
test it very well.

However, there is the MSVisualStudio project on COIN, where the goal is to 
maintain developer studio files for different versions of it 
(https://projects.coin-or.org/MSVisualStudio).  Maybe we can include Ipopt 
in there...?  (JP, in case you are reading this, what do you think?

Yes, the configure and makefiles are not required to be run if you use DS.

I think the problem in this case is that some more files are now required 
by Ipopt with the new Lapack (maybe changed recently).  It seems that the 
source file iparmq.f is not listed in the Lapack subproject, but you shold 
have downloaded it when you got LAPACK.  Maybe it will work if you just 
add this file to the project so that it will be compiled as well... (and 
if there are more unresolved symbols like that, maybe you can find the 
missing source files there as well).

I hope this helps,

Andreas
