To me that looks redundant. 1. buildchroot:do_cleanup task should be executed after all the packages are build, so that's why the following is used: DEPENDS += "${IMAGE_INSTALL}" do_cleanup[deptask] = "do_deploy_deb" 2. buildchroot:do_cleanup should be somehow integrated to Isar pipeline, so some dependency from late task (which runs after packages building) should be added. I chose image:do_populate, so the following line forces Isar to run do_cleanup during build: do_populate[depends] = "buildchroot:do_cleanup" Alex > > Henning > >> do_rootfs[stamp-extra-info] = "${MACHINE}-${DISTRO}" >> >> diff --git a/meta/recipes-devtools/buildchroot/buildchroot.bb >> b/meta/recipes-devtools/buildchroot/buildchroot.bb index >> 6a94733..fe88e98 100644 --- >> a/meta/recipes-devtools/buildchroot/buildchroot.bb +++ >> b/meta/recipes-devtools/buildchroot/buildchroot.bb @@ -67,7 +67,28 @@ >> do_build() { # Install package builder script >> sudo install -m 755 ${WORKDIR}/build.sh ${BUILDCHROOT_DIR} >> >> + # Create share point for downloads >> + sudo install -d ${BUILDCHROOT_DIR}/git >> + >> # Configure root filesystem >> sudo chroot ${BUILDCHROOT_DIR} /configscript.sh >> _do_build_cleanup >> } >> + >> +do_prepare[nostamp] = "1" >> + >> +do_prepare() { >> + sudo mount --bind ${GITDIR} ${BUILDCHROOT_DIR}/git >> +} >> + >> +addtask prepare after do_build >> + >> +DEPENDS += "${IMAGE_INSTALL}" >> +do_cleanup[deptask] = "do_deploy_deb" >> +do_cleanup[nostamp] = "1" >> + >> +do_cleanup() { >> + sudo umount ${BUILDCHROOT_DIR}/git >> +} >> + >> +addtask cleanup after do_prepare > -- With best regards, Alexander Smirnov ilbers GmbH Baierbrunner Str. 28c D-81379 Munich +49 (89) 122 67 24-0 http://ilbers.de/ Commercial register Munich, HRB 214197 General manager: Baurzhan Ismagulov
