Re: isalnum not declared


I actually tried to change the headers, but it did not help (the difference
was that compiler did not go through
/usr/include/c++/3.2.3/backward/iostream.h:32, but the same error occured
again when compiler reached the cctype).

Changing extensions does not seem feasible, because I am using FLEX
( - the third party code with many .c

The key point, I think, is that compiler does not see 'isalnum' etc in
cctype.  How is it possible?

| Hi Nikolai,
| It looks like your old source uses old C++ (pre-ISO 14882 standard) header
| files.  It probably also does not use compliant namespaces.
| Change the header files to compliant ones (e.g., #include <iostream.h>
| becomes #include <iostream>).
| And add in std:: by either "std::ID"prefix in front of each standard
| namespace identifier (metasyntactically given here as "ID"), or "using
| std::ID" near the top of the source file, or just carte blanche by "using
| namespace std;" after the #include specifier block near the top of the
| source code.
| You might also want to change the ".c" extension to ".cpp".
| HTH,
