hi all ,
while compiling md5.cc file for md5 algorithm in fedora 7 i got the following errors . i am unable to figure out the problem please do tell me the solution to remove the bug as soon as possbile..
[root@localhost md5-cc]# gcc md5.cc

Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <iostream> instead of the deprecated header <iostream.h>. To disable this warning use -Wno-deprecated.

waiting for response
thanks

We'll need to see your code, but on first glance it appears you have included unsupported non standard or deprecated header files in your project. If you post the code, we can tell for sure.

I have the same problem when trying to compile the same thing under Ubuntu 7.10 amd64.

The source comes from here under the "C++" header.

As you understand, I too would be very greatful if some advice on how to get it to compile could be provided.
