Patrick Williamsc124f4f2015-09-15 14:41:29 -05001# IceCream distributed compiling support
2#
3# Stages directories with symlinks from gcc/g++ to icecc, for both
4# native and cross compilers. Depending on each configure or compile,
5# the directories are added at the head of the PATH list and ICECC_CXX
6# and ICEC_CC are set.
7#
8# For the cross compiler, creates a tar.gz of our toolchain and sets
9# ICECC_VERSION accordingly.
10#
11# The class now handles all 3 different compile 'stages' (i.e native ,cross-kernel and target) creating the
12# necessary environment tar.gz file to be used by the remote machines.
13# It also supports meta-toolchain generation
14#
15# If ICECC_PATH is not set in local.conf then the class will try to locate it using 'bb.utils.which'
16# but nothing is sure ;)
17#
18# If ICECC_ENV_EXEC is set in local.conf, then it should point to the icecc-create-env script provided by the user
19# or the default one provided by icecc-create-env.bb will be used
20# (NOTE that this is a modified version of the script need it and *not the one that comes with icecc*
21#
22# User can specify if specific packages or packages belonging to class should not use icecc to distribute
23# compile jobs to remote machines, but handled locally, by defining ICECC_USER_CLASS_BL and ICECC_USER_PACKAGE_BL
24# with the appropriate values in local.conf. In addition the user can force to enable icecc for packages
25# which set an empty PARALLEL_MAKE variable by defining ICECC_USER_PACKAGE_WL.
26#
