Problem with macro expantion when '::' is within a string

[Lars Holm <lars.holm@xxxxxxxxxxxxx>]

Hi!


I have problem with the preprocessor . The thing I try to do is beneath
I have this macro and will expand it.


#define FOO(a,b)  a##::Foo(#b)
            
The compiler complains with:

foo.cxx:35:41: pasting "txBoolean" and "::" does not give a valid preprocessing token

It seems to me that the concatenation fails when one of the strings contains '::'.

Is  there any solutions on this problem
