# IceCream distributed compiling support
|
|
#
|
|
# Stages directories with symlinks from gcc/g++ to icecc, for both
|
|
# native and cross compilers. Depending on each configure or compile,
|
|
# the directories are added at the head of the PATH list and ICECC_CXX
|
|
# and ICEC_CC are set.
|
|
#
|
|
# For the cross compiler, creates a tar.gz of our toolchain and sets
|
|
# ICECC_VERSION accordingly.
|
|
#
|
|
#The class now handles all 3 different compile 'stages' (i.e native ,cross-kernel and target) creating the
|
|
#necessary enviroment tar.gz file to be used by the remote machines.
|
|
#It also supports meta-toolchain generation
|
|
#
|
|
#If ICECC_PATH is not set in local.conf then the class will try to locate it using 'which'
|
|
#but nothing is sure ;)
|
|
#
|
|
#If ICECC_ENV_EXEC is set in local.conf should point to the icecc-create-env script provided by the user
|
|
#or the default one provided by icecc-create-env.bb will be used
|
|
#(NOTE that this is a modified version of the script need it and *not the one that comes with icecc*
|
|
#
|
|
#User can specify if specific packages or packages belonging to class should not use icecc to distribute
|
|
#compile jobs to remote machines, but handled localy, by defining ICECC_USER_CLASS_BL and ICECC_PACKAGE_BL
|
|
#with the appropriate values in local.conf
