g++ error: ‘stricmp’ was not declared in this scope (but OK for 'strcmp')

Question

I am trying to compile the following very very simple piece of source code:

#include <cstring>
// #include <string.h>
// using namespace std;

class Helper {
public:
    int cStringsAreEqual(const char *s1, const char *s2) {
        return stricmp(s1, s2);
    }
};

... but I am getting the following error message:

   g++ error: ‘stricmp’ was not declared in this scope

However when I use strcmp() instead of stricmp() then everything is fine!

What can be wrong here? Shouldn't stricmp() be allowed when strcmp() is allowed?

Sureley, this all could be written in a much better way without using strcmp/stricmp.

But that's not the point here.

I am porting a piece of software - which makes much use of calls to stricmp(). And if somehow possible I would like to avoid all of the efforts needed to change every call to stricmp.

Any help on this would be very much appreciated!

BTW: I am using Ubuntu karmic OS (v9.10) with g++ v4.4.1.

BTW: as you can see I also made some trials with '#include string.h' or with 'namespace std' but nothing helped.

Answer 1

stricmp is neither POSIX nor ANSI, so it doesn't really matter if strcmp is allowed, if your compiler or standard library is strictly adhering to POSIX or ANSI standard library functions (as is probably the case with the GCC suite).

Answer 2

Try strcasecmp(). Here's the manual page for it. It is conforming to 4.4BSD and POSIX.1-2001.
