Hi there
I am using the strip command directly on my executable without any options like -u -r etc.
For example in the terminal I used to write
strip /Users/admin/Desktop/Test.app/Contents/MacOS/Test
When I use this in Tiger it used to work fine by not showing the symbol table on nm command execution in terminal.
However in Leopard the same strip command does not work so that even after the nm command execution the symbol table is shown as in prior strip command execution.
Please note I am using Xcode 3.0 in Leopard, even tried with latest Xcode versions.
Another add up is Test.app has 2
staticlibs..
Thanks in advance for any input..
Regards
Jakob

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
00001fd8 t __dyld_func_lookup
00001000 A __mh_execute_header
00002004 D _environ
U
_exit
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?
