migrate CString in MFVC onto Linux

[Nick]

Hi,

I am almost a C++ newbie, and trying to migrate a VC++.net code onto a
Linux machine. The code uses a lot of cstring. On Linux, I found an
include file called cstring, so I include it into the code. But the
compiler always says:
error: identifier "cstring" is undefined
So, is there any easy way to solve it? Should I define a cstring class
by myself? Apparently I cannot just use typedef char* csthing, since
all its methods used in the code get lost.

Thanks for your help.

You have access to the MFC source code so it may be worth porting the
CString class over to your Linux compiler. Alternatively replace all use of
CString with std::string though this would probably require lots of code
changes as the two classes are not compatible.

The header <cstring> has nothing to do with MFC's CString class.

You would have to define "easy".

I would rather replace all references to CString with std::string
and fix those things that don't compile. That way you will get your
code to comply with the Standard on any platform with a recent C++
compiler.

Yes, apparently.
