1 # IceCream distributed compiling support
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
8 # For the cross compiler, creates a tar.gz of our toolchain and sets
9 # ICECC_VERSION accordingly.
11 #The class now handles all 3 different compile 'stages' (i.e native ,cross-kernel and target) creating the
12 #necessary enviroment tar.gz file to be used by the remote machines.
13 #It also supports meta-toolchain generation
15 #If ICECC_PATH is not set in local.conf then the class will try to locate it using 'which'
16 #but nothing is sure ;)
18 #If ICECC_ENV_EXEC is set in local.conf 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*
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 localy, by defining ICECC_USER_CLASS_BL and ICECC_PACKAGE_BL
24 #with the appropriate values in local.conf
