RE: [openrisc] fopen() not defined??

["rchowdsl" <rchowdsl@pacbell.net>]

Hi Simon,

Let me see if this will help.

I'm trying to read in a data file by using fopen and
the data goes to memory on the or1k hardware, this
is mainly for testing purpose where i can have one
same firmware but run different tests by downloading
different memory image.

I was able to do this with an ARM based system using
the Greenhills debugger where the debugger provided
the fopen functionality.

-am i making any sense? BTW, thanks a lot for helping
-Raymond

Hi Raymond,

I still don't understand what do you want to do.

This might sound silly, but if you are compiling program that will run
on your host machine, then you should use cc or gcc instead
or32-uclinux-gcc.
