I've got two Macs here, one for development and one for testing. I
build on the development machine and copy the app bundle over to the
tester. It runs fine on both, but on the test machine I get errors if
I try to attach to it in gdb, or even use tools like 'nm' or 'atos'
on its binary.
gdb on launch prints a long list of:
unable to read unknown load command 0x1b
There are about 20 of those lines, some with 0x1d or 0x1e or 0x1f; then:
bfd_mach_o_scan: unknown architecture 0x1000007/0x3
then a bunch more load command errors.
The 'nm' command prints:
nm: for architecture ppc7400 object: Cloudy malformed object (unknown
load command 8)
There's no difference whether I copy the app using rsync or AFP.
The dev machine is a MacBook Pro, the tester a G4 Mac Mini. Both run
10.5.2. I do a fat build in Xcode, of course, so it'll run on both.
It's a debug build so it should have full symbols.
Any ideas? Is something misconfigured on the test machine?
