Hi, the library I try to compile uses a member function named tell. Anyhow the DMC file IO.H seems to get included somewhere which defines tell as a macro (line: 117) leading to undesired macro expansion. What to do in such a case? Why is this macro definition done?

What about #undef?

I tried it in my main program, but the include hierarchy seems to get the definition in somewhere. So I would have to change the vendor supplied code in that I just use an #undef before the specific line of code. I'm not sure if this is the way to go...

Isn't it that such "compiler internal/implementation dependend" symbols should use a _ or even a __ as first char(s) to avoid such problems? Robert

Yes, but then there's the issue of compiling legacy code.

I suggest just commenting out the tell() definition that's causing grief.
It's not sacred <g>.

Hi, ok I do that. But for what kind of code is this define needed? Robert

tell() is an old unix-ism.
