Brian,
As I cut and pasted main.c from this e-mail it wouldn't compile... do
to a number | (pipes) showing up. What I got was
#include <stdlib.h>
#include <stdio.h>
int main ( )
{
| | | | printf("hello world\n");
}
(I had to edit this to make them visible in the e-mail.)
but when I removed them.
#include <stdlib.h>
#include <stdio.h>
int main ( )
{
printf("hello world\n");
}
it worked fine here on 9.1 with gcc3. It's possible I guess that your
e-mail client inserted the pipes or mine did when cutting or pasting...
not sure. The important part is that it compiled, and ran, as expected.
What I'm running.
Mandrake 9.1
Kernel 2.4.21-18mdk (stock)
libgcc1-3.2.2-3mdk
gcc-cpp-3.2.2-3mdk
gcc-3.2.2-3mdk
gcc-c++-3.2.2-3mdk
my uname -a
Linux jamlin.linuxpda.biz 2.4.21-0.18mdk #1 Wed Jun 4 12:38:37 MDT 2003
i686 unknown unknown GNU/Linux
If you note I'm not using the enterprise version of the kernel. I'm
instead using the standard. Since in my case our workstations don't
seem to benefit from it at all. (ie no performance change, or other
gain)
