Re: [Getfem-users] New to GetFEM/ mUF not found error

Dear Khan,

I think the problem is your first error message. Your GCC compiler is probably older and doesn't understand unique pointer type.
You can solve it by either installing the latest GCC, or, since you are working on Windows, consider using Microsft Visual C++.

Best regards,

Dear Member,

I am using getFEM on windows and has made the files using MinSYS and MinGW. I am using Eclipse for C++ editor and complier. for the example given on the tutorial i am getting following error message. Being new to C++ i am unable to understand the error. and the method to remove this
