[Ipopt] Cannot build Ipopt on Windows with MSVC

[Stefan Vigerske]

Hi,

it seems that configure failed to recognize your Fortran compiler:

configure: Trying to determine Fortran compiler name
checking for ifort... no
checking for fl32... no
checking for compile_f2c... no
configure: WARNING: Failed to find a Fortran compiler!


Without a Fortran compiler, it will not build ThirdParty/Blas. 
Therefore, the configure in the Ipopt subdirectory didn't "find" Blas 
(i.e., recognize that "coinblas" will be build):

checking for COIN-OR package Blas... skipped check via pkg-config, 
redirect to fallback
checking for COIN-OR package Blas (fallback)... no, dependency coinblas 
not available

I don't recall at the moment what all the flags to ifortvars.bat mean, 
but are you sure that "-platform linux" is correct.
After you started cygwin and the MSVC/Intel batch files went through, 
the ifort executable should be in your path.

Stefan

PS: The installation instructions in the Ipopt manual might be a bit 
outdated. Could be that one now should use --enable-msvc instead of 
--enable-doscompile=msvc. But without GCC in the path, it may also work 
without any options to configure.
