Hi all,
I crosscompile the gdb server for sh and I have trouble to debug a
simple application,
using it.
I try with the gdb-6.8
./configure --target=sh4-linux
gdbserver
sh3-linux-gcc is a nptl toolchain
CC=sh3-linux-gcc ./configure --host=sh4-linux
server side
./gdbserver-6.8 192.168.10.156:1234 ./foobar_sample
Process ./foobar_sample created; pid =
817
Listening on port
1234
Remote debugging from host 192.168.8.242
client side

This is how the toolchain is configured
sh3-linux-gcc -v
Using built-in specs.
