Re: [Qemu-devel] latest qemu with gdb remote not working

[Peter Cheung]

Dear Maydell

    I just tried to compile the latest qemu on Fedora 18 64 bits, it is also fail. When i press "c" in gdb, the qemu won't start running.

But one thing fedora is different than mac, when i connect gdb to qemu, it won't say "warning: Error 268435459 getting port names from mach_port_names"

In my mac, i use gcc from mac port, here is the version detail:

/Users/peter>gcc -v

Using built-in specs.

Target: i686-apple-darwin11
