# The operation of the build system can be tuned using the following variables,
|
|
# which can be specified at the command line or supplied via the
|
|
# 'etc/build.conf' file.
|
|
#
|
|
# BASE_DIR - this directory points to Genode's 'base' repository
|
|
# REPOSITORIES - list of directories incorporared into the build process
|
|
# VERBOSE - variable that controls the verboseness of the build process
|
|
#
|
|
# By default, compiler messages are not displayed. If you are
|
|
# interested in these messages set this variable to nothing.
|
|
# ('VERBOSE=')
|
|
#
|
|
# VERBOSE_MK - variable that controls the verboseness of make invocations
|
|
# VERBOSE_DIR - variable that controls the verboseness of changing directories
|
|
#
|
|
# Using this variable, you can enable the make messages printed
|
|
# when changing directories. To enable the messages, set the
|
|
# variable to nothing.
|
|
#
|
|
# LIB_CACHE_DIR - location of the library build cache
|
|
#
|
|
# This variable defines the place for the library build cache.
|
|
# Normally, the libcache is located at 'var/libcache' and
|
|
# there is no need to change it.
