@rlaemmert - that may be related to the libgdbr

radare commented 10 years ago

Different register profile maybe?

Try adding -D gdb

It worksif run it as r2 -a x86 -b 32 gdb:// but when loaded it shows only zeroes in p* output

Rio is broken now for debuggers. Current issue is not gdb specific

The r_io should be fixed now. use -D too, this will enable the io.raw=true and cfg.debug=true Please verify

rlaemmert commented 10 years ago

Hm nothing gdb specific seems to work now. Just tested the connection to my qemu win8 x64 instance...

radare commented 10 years ago

I cant manage to get --no-start or --gdb working beside iits listed in winedbg help.

We need a gdbserver implementation in r2. Anyone? :)

We need a fully working debuggin facility first :P Write registers would be nice

All debuggrrs only work if loaded with -n. Will look at this bug later, but the io seems to work better now

Thanks for providing the pcap file! Had a more indicative error in winedbg when I was looking into it recently so I'll take another look. Didn't think anyone uses it until now..

According to Wine devs, the gdb implementation isn't really in use so there might also be some issues on their side. Have you tried debugging wine processes with regular gdb? It should be possible.

gtors commented 4 years ago

Yes, gdb works well. At least I can use breakpoints.

yossizap commented 4 years ago

Great! Will still look into it but at least you have other options for now :) Just use gdbserver with r2 instead of gdb.
