Subject: Cross compiler questions
Date: Fri, 16 Nov 2007 07:59:09 -0600 [thread overview]
Message-ID: <20071116135909.GA19085@lenovo> (raw)
I am trying to get my mind wrapped around how OE handles
cross-compiling. The first question is where is the cross compiler
tool chain getting pulled into the build queue?
I am greping for gcc-native and quilt to figure out how they are
included or required? I see a PREFERED_VERSION set in the distro. Is
PREFERED_VERSION a method of including dependancies?
Also, the tmp/cross directory has three distinct file groupings.
dfarning@lenovo:~/oe/oetmp$ find cross -maxdepth 3 -type d
cross
cross/i586-angstrom-linux
cross/i586-angstrom-linux/bin
cross/lib
cross/lib/gcc
cross/lib/gcc/i586-angstrom-linux
cross/i686-linux
cross/i686-linux/i586-angstrom-linux
cross/i686-linux/i586-angstrom-linux/lib
cross/i686-linux/i586-angstrom-linux/include
cross/bin
cross/libexec
cross/libexec/gcc
cross/libexec/gcc/i586-angstrom-linux
cross/include
cross/share
What is the difference between
cross
cross/i586-angstrom-linux
cross/i686-linux/i586-angstrom-linux
Why are thing different things being placed in different dirs?
Thanks
David Farning
