Hi,

I have written an application in windows using mfc (microsoft foundation class) c++. What could be the solution it to migrate to linux?

Rewrite it without using mfc.

The whole program structure is based on mfc libraries, isn't there really any other alternatives?

To be honest it has been a long time since I worked with mfcs (20 years+), so maybe someone else can offer another avenue. But I am not aware of any "conversion" method other than writing new classes with the same interface and/or function provided by the mfcs.

The mfcs are very non-portable as I recall, largely because they bind tightly to Window$ core/kernel types and features.

*** Added comment: I just did a quick search and did not see any other path prominently mentioned. It will likely be a lot of work and involve more than a simple one-to-one code rewrite for a large application, but is of course doable.

MFC was specifically designed to not be portable.

The only place you will find something similar would be buried in the wine project. But I have no idea how hard it would be to extract.

You might find some help from

note the legal warnings - a lot of MFC is composed of macros... which could present legal issues.
