Dev-C++ 4 has an altered Mingw directory structure, for the sake of
"user-friendliness".
Dev-C++ 5 however, comes with an unaltered Mingw directory structure.
I think it's best if you uninstall Dev-C++, remove C:\Dev-C++, and
reinstall it again.

Could you post the entire error message?

Thus, these alterations must be thought to be improvements by those who made them. But, they do not appear to be improvements to me, for what once worked perfectly, now does not work at all. Thus, there is information about the beta which others have, and which I do not.

Dev-C++ 5's new design broke some compatibility with version 4. I think
you should try to port your old projects to version 5.
I'm using Dev-C++ 5 for production, and in my opinion, a Makefile-based
system is an improvement.
