Re: [linuxsh-dev] native GDB

[Denis D. <dp...@pr...>]

First you need to apply all of the patches in sh-gdb-patch.tar.gz to the
gdb sources.
I am using the following lines to build gdb and gdbserver. 
It all builds but is not tested yet.

# Build gdb-client for cross-debugging
./configure --build i386-linux-gnu --host i386-linux-gnu --target
sh-linux-gnu
mv gdb/gdb gdb/gdb-client
make distclean

# Build gdb for native debugging
./configure --build i386-linux-gnu --host sh-linux-gnu --target
sh-linux-gnu
make

# Build gdbserver for cross-debugging
cd gdb/gdbserver
../../configure --build i386-linux-gnu --host sh-linux-gnu --target
sh-linux-gnu --prefix
make CC="sh-linux-gnu -ml -m4"

Hope this works for you. Let me know how you get on.

Regards,
Denis.
