# Please note, this script has been designed to work with Gentoo's crossdev, it may or may

|
|
# not work with cross-toolchains that were build differently.
|

|
|
#
|
||
|
|
#
|
||
|
|
# Usage: "./icecream-create-env" creates a native environment(similar to icecc --build-native)
|
||
|
|
# "./icecream-create-env prefix" creates a cross-compile environment using the cross-toolchain created by crossdev
|
||
|
|
# Example:
|
||
|
|
# "emerge crossdev && crossdev -t sparc-unknown-linux-gnu && icecream-create-env sparc-unknown-linux"
