'::memcpy' has not been declared

[bisforbenson]

I'm trying to compile things with gcc 4. After running the following
command:

% gcc -O3 -g -Wall -Wno-unused -DLINUX -D_REENTRANT -o ../../obj/egi.o
-I../../include/ -I... [bunch of include directories] -c egi.cpp

i get the following errors:

/usr/lib/gcc/i386-redhat-linux/4.0.1/../../../../include/c++/4.0.1/cstring:79:
error: '::memcpy' has not been declared
/usr/lib/gcc/i386-redhat-linux/4.0.1/../../../../include/c++/4.0.1/cstring:80:
error: '::memmove' has not been declared
[and so on]

Anyone know how to fix this? I didn't get this with gcc 3.3...

TIA,
benson

Did you include <memory.h> or <cmemory>?

If you used <cmemory>, memcpy is in namespace std

 

[benson]

It goes beyond just the memory functions. Below is more of the stuff
that i cut out. That the error is occuring in the cstring means that
something weirder is afoot. In any case, i tried including "memory.h"
(<cmemory> didn't work), but it didn't help.

thanks,

Neither of those are standard headers.
memcpy and memmove are defined by <cstring>, which puts them
into namespace std, as you noted.

Crap. For some reason, I thought they were standard. I stand corrected.

<snip the rest>

(gcc-specific)

If your header files are like mine for gcc, then <cstring> includes
<string.h>, which should define those symbols that are missing.

Have you defined your own string.h and somehow gotten it into the system
path?

[benson]

You're right that there's another string.h, but shouldn't the brackets
around <string.h> give precedence to the /usr/include directory? The
string.h in my code comes from FLTK. I'm not sure of the proper
workaround. Please advise.

The search path meanings for "" and <> is implementation defined.
