# 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 # #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 ######################################################################################### #Error checking is kept to minimum so double check any parameters you pass to the class ########################################################################################### def icc_determine_gcc_version(gcc): """ Hack to determine the version of GCC 'i686-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc. build 5363)' """ import os return os.popen("%s --version" % gcc ).readline().split()[2] def create_cross_env(bb,d): """ Create a tar.bz2 of the current toolchain """ #
