| # 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 environment 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 'bb.utils.which' |
| # but nothing is sure ;) |
| # |
| # If ICECC_ENV_EXEC is set in local.conf, then it 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 locally, by defining ICECC_USER_CLASS_BL and ICECC_USER_PACKAGE_BL |
| # with the appropriate values in local.conf. In addition the user can force to enable icecc for packages |
| # which set an empty PARALLEL_MAKE variable by defining ICECC_USER_PACKAGE_WL. |
