# NetSurf continuous integration build script for jenkins
#
# This script is executed by jenkins to build netsurf itself
#
# Usage: jenkins-build.sh
#

# TARGET is set to the frontend target to build
# HOST is set to the identifier of the toolchain doing the building
# CC is the compiler (gcc or clang)
# BUILD_NUMBER is the CI build number

#####

# set defaults - this is not retrivable from the jenkins environment
OLD_ARTIFACT_COUNT=25

################# Parameter and environment setup #####################

IDENTIFIER="$CC-${BUILD_NUMBER}"

# Identifier for build which will be cleaned
OLD_IDENTIFIER="$CC-$((BUILD_NUMBER - ${OLD_ARTIFACT_COUNT}))"
