Re: Croostools cript fails to compile GCC in cygwin. What am i missing?

[Ryan Churches <ryan dot churches at gmail dot com>]

Solved:

something about my cygwin install was preventing me from compiling.

I reinstalled cygwin, and added the following packages not included in
the cygwin default install:  automake, autoconf, bison, flex, gcc,
make, and wget.  They pulled in some dependencies themselves.  I'm not
sure if all of the ones i listed are essential, but i now most of them
are.  i probably forgot to list one or more.

Wget made the script run very automagically.

Dan suggested i mount the crosstools installer in a managed cygwin
directory, and i did that, just in case the clean install wasnt
enough.
