Migrating C++ source from Microsoft Windows NT to SCO Unix

[Timothy_Ko at nag dot national dot com dot au]

Hi,

Recently, we downloaded and installed the current release (2.95.2) of GNU
Compiler Collection (GCC) for a SCO OpenServer 5.05 Unix machine.

I've verified some of the gcc setting by compiling a simple cpp file with
namespace std, #include <string>...

     g++ -o test test.cpp

and was success.


Then I try to migrate our existing C++ source from Microsoft Windows NT to SCO
Unix which is developed from Visual C++ 6.0.

However, it comes up syntax errors.
I'm not sure that's incompatiable between Windows and Unix,
or because of I compile without using a makefile,
or gcc installation problem.

Some of the errors like:

1.   NabTime.h:82: syntax error before `;'

     where we declare as:
     __int64         m_iTime64;

2.   NabString.h:594: macro `isalnum' used without args

     where we declare as:
     virtual const bool NabString::isalnum() const;

3.   NabString.h:44: sstream: No such file or directory

Thanks

Tim
