[Buildroot] Help Building Buildroot

[A M <madwifi@vermark.com>]

Update:

I grab a fresh buildroot and start from scratch. I was able to run make
successfully if I use the default configuration. But I ran into similar
problem with I tried select some options/packages. Here is part of the
error message I got:

                                make: ***

I tried a different approach by going directly to the ccache directory
and setting the PATH to:

export PATH=
$PATH:~/development/1.0/buildroot/build_i586/staging_dir/usr/bin/

and 

CC=~/development/1.0/buildroot/build_i586/staging_dir/usr/bin/i586-linux-uclibc-gcc

I ran ./configure with the above options and got this:

        configure: Configuring ccache
        checking for i586-linux-gcc... i586-linux-gcc
        checking for C compiler default output file name... configure:
        error: C compiler cannot create executables
        See `config.log' for more details.

It seems like something is wrong with my compiler.

Has anyone come across this?


Thanks again.

A M
