[Ipopt] Cannot build Ipopt on Windows with MSVC

Wed Aug 31 07:59:00 EDT 2016

Hi,

you might want to decide first whether you want to build 32bit or 64bit 
binaries. That is, use -arch ia32 for the ifortvars if your MSVC is 
32bit and use -arch intel64 for the ifortvars if your MSVC is 64bit.

In the output you send, configure tried to use the Intel C/C++ compiler 
(icl) and that didn't seem to work. There is this strange line in 
config.log:

link: cannot create link 'conftest.obj' to 
''$'\357\273\277''-out:conftest.exe': No such file or directory

Maybe it didn't work because you only run ifortvars (?).
You can force it to use the MS compiler by passing CC=cl CXX=cl to 
configure.
