Hello,

I'm playing with the trial version of SNOPT as my department is interested to buy a license.

Scrolling down the FAQs of SNOPT's website I noticed that to be compiled in Win10 only the commercial Intel fortran can be used. Is that really the case?

This means that on top of SNOPT license one needs to buy also an expensive license for a fortran compiler when gfortran has a long established heritage. Do you have an alternative toolchain to suggest for that?

You can use gfortran. I've successfully compiled with mingw/cygwin and gfortran on Windows. Pretty much every user on Windows that I've communicated with is using Visual Studio with the Intel compiler so that's what we provide.

Dear Elizabeth,

many thanks for your reply. Glad to hear that, but can you elaborate a bit more, please? Since g-fortran is not officially supported by Mathworks, the process is not very clear. I just gave a try by installing independently MinGW to compile the example file timestwo.F and when I tried

mex -setup

Matlab was not able to detect g-fortran, since it only looks by default at the Intel's compilers. (please, see below)

Oh Matlab...

My information was on compiling the Fortran/C/C++ libraries. I didn't realize you were interested in Matlab. Unfortunately, Matlab only supports gfortran on Linux platforms and only the Intel compiler on Windows and macOS. In fact, I am in a similar situation as you as my group licenses the Intel compiler so that we can compile and provide libraries to our users.

If you are interested in purchasing SNOPT, we do provide compiled libraries and Matlab files so you should not need to compile the code yourself. If you can use our trial versions of SNOPT, you should be able to use the fully-licensed version as well.

Hi Elizabeth,

I'll talk about it with my dept head. Meanwhile I'll keep testing the trial version.

Thanks for your reply!

marsag/Elizabeth, just posted my "CmakeLists.txt" file in the other thread that worked for me w/ MinGW gfortran 64-bit compiling toolchain.
