unable to build gdb on Linux   
Hi,
It build x86, but fails for ARM i haven't checked other targets as i am only interested in ARM.
Is this expected? if not any workarrounds ?

Hi Prem,

If you just want to build all of the Linux hosted gdbs, then in your root gdb directory type 'make OSLIST=linux'. I 
think this is what you want to do.

But if you are trying to build on a Linux host Neutrino hosted gdbs, then you will have to modify your $QNX_TARGET/usr/
include/mk/build-cfg file.

 linux-linux)
         make_CC="gcc"
         ;;

Even if you make the following changes to your build file, you will be unable to go into the root gdb directory and type
 make with no parameters. You would have to type 'make OSLIST="nto linux" unless you have an existing linux-mingw 
toolchain.

Sorry, I made a small typo in the last patch.

Hi,
Thanks for the patch, I am compiling both GCC and GDB at the moment.

I'll post the results once it is done

Re: unable to build gdb on Linux   
Bingo..
Now gdb is built, I am trying to build gcc now.
Can I make a native toolchain for amd64 by copying over linux-x86-o-ntoarm to linux-amd64-o-ntoarm. Though i dont expect
 to pass it for the first time I believe it should be possible.
I run a 64 bit linux at home and I see a tremondos increase in speed with 64bit applications. I'll give it a try in the 
evening.
