Re: Newlib port for new architecture

Hello Varun,

I would not use a Windows host to do this work. Its probably much times faster if you do this on a Linux machine. I would also use a Git clone of Newlib to do the development.

I am using Cygwin to configure the newlib in windows environment [ I wanted to check if build for arm is working before I start porting code for tricore arch]
I am trying to use pre-built gcc image of arm [SysGCC ] for trial purpose. It is added in path variable, still not getting recognized.  Attaching the logfile also.

Any help would be appreciated!!!

See `config.log' for more details.

It seems you need a native GCC installed. I would really use a Linux machine, just select the C/C++/kernel development packages and everything should be available.
