Programming

I am running a linux-x86 machine with Ubuntu 9.10. Currently we are trying to re-build the data acquisition system in my lab, and to do this we must interface the linux machine with a VME crate via codaLite.

My question pertains to the compilation error I am receiving from g++. At the top of the file cMsgRoc.cc the header file exists as

#include <string>
etc etc

the string.h file exists in /usr/include and contains the corresponding function so that I'm assuming it is up to date.

I've hit a stand-still and would really appreciate any help! Thanks in advance!

#include <string> includes something like /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/include/g++-v4/string, and not /usr/include/string.h. The C++ string headers have nothing to do with the C ones. Try adding the line

Code:

#include <string.h>

Or even strings.h, as strncasecmp's manpage suggests it needs.

Thanks for the fast reply, I'll give it a try.
