modify build_pyoptsparse.py work on windows 64 bit machine

[venkatgmrit05]

this script works for linux only and has issues working with windows 64 bit machine. Is this resolved elsewhere?

one of the issues faced :

the current env has python 11 32 bit

It looks like your screenshot truncated the actual error.

Hello. Did anyone have a chance to look at this? Thank you.

No, the script wasn't developed or tested in a native Windows environment. Though there are plans to do so eventually, it will be some time, weeks or months, before that happens. Additionally, it doesn't seem to be a superficial problem - it looks like it dies attempting to run the first script in the first package it attempts to compile.

Some possible workarounds in the meantime are:

• Install all of the packages with Anaconda if you can. They're available on conda-forge, though I can't for sure if builds exist for Windows.
• Install and run from the Cygwin environment, which provides many of the same tools and libraries available on Linux as well as the pathname convention. This will definitely make it easier to build the source packages.

Unfortunately, We cannot use anaconda. conda-forge is fine but when we fire walled repo.anaconda , conda forge is not working as well. so installing pyoptspare with ipopt [which works just fine] is not an option for us.

When building from Cygwin environment, will it build the modules for windows os?

Must it be Cygwin? Can it be msys2?

Could you elaborate on "run it from Cygwin environment"? i am not familiar with this cross platform concepts (at all). pls forgive my ignorance. Thank you.
