The icecc class often calls 'which' for determining paths. This leads to many messages on stderr in case 'which' doesn't find the executable. Using bb.utils.which is more appropriate here and doesn't pollute stderr.

# 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 '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. In addition the user can force to enable icecc for packages
|
|
#which set an empty PARALLEL_MAKE variable by defining ICECC_USER_PACKAGE_WL.
