| Issue |
Using "cc -c file.cc", I tried compiling the following very small files:
File 1:
x09#include <wcskip.h>
x09#include <wcskipit.h>
x09WCValSkipListSet<int > dummy;
File 2:
x09#include <wcskip.h>
x09WCValSkipListSet<int > dummy;
x09#include <wcskipit.h>
File 1 compiles without errors. File 2 gives errors from deep in Wcskipit.h's include files.
The situation occured because I had a header file containing:
x09#include <wcskip.h>
x09class Derived : public WCValSkipListSet<Parameter > { ... };
and the corresponding source file containing
x09#include "header.h"
x09#include <wcskipit.h>
As far as I know, I have not made a technical error in organizing my include files. What's the significance of this error in relation to the reliability of the Watcom C/C++ compiler.

This actually *is* a technical error. You're not supposed to do any work within your #include file lines. This affects the pre-processor.
This is an accepted compiler fact. |
