Emacs 24.3 gdb mode doesn't work on OSX 10.7.5

Emacs 24.3 gdb mode doesn't work on OSX 10.7.5

[Steven Wu]

hi,

I am having trouble to get Emacs gdb working correctly. When I do m-x gdb with argument --annonate=1 -i mi, I got this

See the (gdb) prompt is in the middle, and also, when  gdb-many-windows is set to t, I cannot get the Primary Source buffer to show program execution progress, and the other buffers, like the stack frame, register buffers etc show nothing. Gdb works with gud-gdb, does anyone know what the problem is?

Thanks

Why did you use --annonate=1?  That's not the default.  Do the
problems disappear when you don't use that option?

They do.  I tried --annotate=3 -i mi, and I had

I got the same thing, all other buffers did not have any activity. The only difference is the gud buffer had strange outputs.

I am not quit sure what the problem is.

Please try without --annotate= at all, and see if the problem
persists.

[Steven Wu]

Almost the same as --annotate=1, but less verbose, and the rest of the buffers behaved the same way.

If -i mi has no effect when you invoke GDB from the shell prompt, then
it's definitely not an Emacs problem.

Well, when I invoked gdb -i mi … from shell, it kind of worked like regular gdb except it printed out ~ at the beginning of lines, and echoed commands out. I assumed that was correct behavior for gdb -i mi, right?

GDB/MI prints ~, but it also changes the output format.

But gdb--check-interpreter only looks at the first character.
