HP C Preprocessor

Srinivas Sreekumar — Fri, 18 Jan 2002 17:43:49 GMT

Hi Admins,

We moved some of the sources from one machine to another.On new machine the preprocessor is HP92453-01 B.11.11.02 HP C Preprocessor and on the old one it is HP92453-01 A.11.00.13 HP C Preprocessor. While compiling it gives problem due to version difference.
Is there any way to overcome it? (with some options)

Thanks in advance,
Srini

I doubt that the cpp is the culprit; the problem is
more likely in your systems' C or math libraries.

But to see what cpp is up to, simply add the -E
option to the cc command line: "cc -E *.c > logfile".
Then "logfile" will contain the processed version
of your source code (i.e. with all #define, #include,
etc. directives evaluated). Then you can compare
the results from your two machines to see if there's
a difference.

Hi:

I suspect it is because some environemnt variables are defined differently on the two boxes. This is impossible to diagnose without data. You will need to list a snippet of code and the error messages.
