This is achieved by making the DL_DIR 12# recipe-specific. While reducing disk usage, it increases network usage (for 13# example, compiling the same source for target and host implies downloading 14# the source twice). 15# 16# Because the "do_fetch" task does not get re-run after removing the downloaded 17# sources, this class is also not suitable for incremental builds. 18# 19# Where it works well is in well-connected build environments with limited 20# disk space (like TravisCI). 21 22inherit rm_work 23 24# This would ensure that the existing do_rm_work() removes the downloads, 25# but does not work because some recipes have a circular dependency between 26# WORKDIR and DL_DIR (via ${SRCPV}?). 27# DL_DIR = "${WORKDIR}/downloads" 28 29# Instead go up one level and remove ourself. 30DL_DIR = "${BASE_WORKDIR}/${MULTIMACH_TARGET_SYS}/${PN}/downloads" 31do_rm_work:append () { 32 rm -rf ${DL_DIR} 33} 34
