std::strcpy is not a member

std::strcpy is not a member

[Vardhan, Sundara (GE Infra, Energy)]

Hi All

Recently compiled gcc 4.4.3 for AIX using the following configure
options :

 --with-as=/usr/bin/as --with-ld=/usr/bin/ld
--enable-languages=c,c++,fortran --prefix=/cots/gnu/gcc443
--enable-threads --enable-version-specific-runtime-libs --disable-nls
--enable-decimal-float=dpd --host=powerpc-ibm-aix5.3.0.0

Successfully installed and compiled my application. I get the following
error on the C++ code compilation :
error: 'strcpy' is not a member of 'std'

The source code does have "using namespace std;"

The same source code does not have an issue with gcc 4.2.3 on AIX.  Am I
missing something when building the new compiler version?

I would very much appreciate if you can give me pointers or solution for
this issue.

Thanks in advance

With Regards

Vardhan

Send us a test case.

You really should now this by now, you've been posting here long
enough.

Worked on my machine.

Do you have a small exemplary toy program that exhibits the problem?  To use
as a test case.

But the source code does not have:
#include <cstring>
which is what you need for std::strcpy.

Maybe you #include <iostream> and in 4.2 iostream includes cstring in turn 
but a cleanup in libstdc++ means this is not the case anymore?

Hi Marc

Thanks that was the missing piece. Wonder how the same program compiles
fine in gcc 4.2.3. Perhaps some change that is now required to
explicitly put the header file. 

Thanks a lot

With Regards

Vardhan

Hi Andrew

I apologize for that. Assumed that I would have not built the gcc with
the correct set of configure parameters. Please find below a very simple
test source :

 /*
** Includes
*/
/*START INCLUDE*/
#include <stdio.h>
#include <string.h>


using namespace std;

/* STOP INCLUDE*/

main()
{
 char s[10];

 std::strcpy(s,"NO TAG");
 printf("%s\n",s);

}

Hope this is ok. Thanks much

With Regards

Vardhan

This is not C++, it's C. If you want the C-style string functions
available in the C++ 'std' namespace, you must do:

#include <cstring>

It is also perfectly valid C++03. Now most compilers never implemented 
this properly, and C++0X validates that behavior, so the code won't be 
valid C++0X. But then, IIRC, C++0X also undeprecates the inclusion of 
string.h, so the OP might as well keep including string.h and use 
strcpy (without std::).
