I am experimenting on a Carbon product and I don't want to show the

terminal.
If you build the product in Tiger with Xcode 2.x version and if you
use strip command that works fine by not displaying the text
content of the symbol table on nm command execution. But if you
build it in Leopard Xcode 3.x and use strip command that doesn't
work i.e text content of the symbol table will be shown as was in
original built product. Even if the Xcode 3.x built product which is
been stripped in Tiger does not give the expected behavior.
Any input is greatly appreciated..
The following terminal session shows the output of nm before and after
strip. This is in OS X 10.5. The strip command works as expected.
$ cat test.c
void Silly( void )
{
}
int main( void )
{
Silly();
return 0;
}
$ gcc test.c
$ nm a.out
0000200c D _NXArgc
00002008 D _NXArgv
00001fe6 T _Silly
00002000 D ___progname

00001fee T _main
00002010 d dyld__mach_header
00001fc4 t dyld_stub_binding_helper
00001f84 T start
$ strip -u -r a.out
$ nm a.out
00001000 A __mh_execute_header
U _exit
Note the -u -r options for strip. How does your attempted use of strip
differ?
