how to compile arm target?

[Frogmarch]

I compile with:
./configure --target=arm-linux
make
sudo make install

and run:
arm-linux-gdb vmlinux RAMEDUMP

but still can not debug the ramdump:

this vmlinux and ramdump can be parsed by crash utility

First - in which format this ramdump is? Is it supported by libkdumpfile?

Second - I am sorry to say that ARM is not yet supported. That means at least small part of code handling storing of registers to stack, and the registers from dump.

Third - see the discussion on gdb & gdb-patches mailing list. It can't be used that way, you'd need (after the previous topics are resolved) to run something like "target kdump /file/with/dump".

Fourth - this original gdb-kdump project is discontinued, because it wasn't accepted to gdb upstream. What continues further is development of Python binding to "gdb target". That will offer perhaps more comfortable way of implementing i.e. different CPU architecture or different kernel version handling. You may want to see for yourself:
