Re: Error while crosscompiling ncurses to ARM

[Joyce Tan]

Hi,

I changed 

address@hidden@%arm-linux-gcc%g
address@hidden@%arm-linux-gcc%g

to

address@hidden@%gcc%g
address@hidden@%gcc%g

in config.status but make_keys stills seems to be
compiled with arm-linux-gcc.  I'm using i686 machine
to cross compile into ARM machine.  ahhm, what am i
missing here?

thanks
joyce

here is the compiling error.
