向http://book.yoctoprojectbook.com/index 学习 Yocto。第4章有如下代码
SUMMARY = "Recipe to build the 'nano' editor"
PN = "nano"
PV = "2.2.6"
SITE = "http://www.nano-editor.org/dist"
PV_MAJOR = "${@bb.data.getVar('PV', d, 1).split('.')[0]}"
PV_MINOR = "${@bb.data.getVar('PV', d, 1).split('.')[1]}"
SRC_URI = "${SITE}/v${PV_MAJOR}.${PV_MINOR}/${PN}-${PV}.tar.gz"
SRC_URI[md5sum] = "03233ae480689a008eb98feb1b599807"
SRC_URI[sha256sum] = \
"be68e133b5e81df41873d32c517b3e5950770c00fc5f4dd23810cd635abce67a"
python do_fetch() {
bb.plain("Downloading source tarball from ${SRC_URI} ...")
src_uri = (d.getVar('SRC_URI', True) or "").split()
if 0 == len(src_uri):
bb.fatal('Empty URI')
try:
fetcher = bb.fetch2.Fetch(src_uri, d)
fetcher.download()
except bb.fetch2.BBFetchException:
bb.fatal('Could not fetch source tarball.')
bb.plain("Download successful.")
}
addtask fetch before do_build
python do_unpack() {
bb.plain("Unpacking source tarball ...")
os.system("tar x -C ${WORKDIR} -f ${DL_DIR}/${P}.tar.gz")
bb.plain("Unpacked source tarball.")
}
addtask unpack before do_build after do_fetch
python do_configure() {
bb.plain("Configuring source package ...")
os.system("cd ${WORKDIR}/${P} && ./configure")
bb.plain("Configured source package.")
}
addtask configure before do_build after do_unpack
python do_compile() {
bb.plain("Compiling package ...")
os.system("cd ${WORKDIR}/${P} && make")
bb.plain("Compiled package.")
}
addtask compile before do_build after do_configure
do_clean[nostamp] = "1"
do_clean() {
rm -rf ${WORKDIR}/${P}
rm -f ${TMPDIR}/stamps/*
}
addtask clean
配方位于 meta-hello/recipes-editor/nano。基本上它正在尝试构建一个nano 文本编辑器包。 do_fetch() 任务失败。经过一些打印语句调试后，我发现失败发生在这一行：src_uri = (d.getVar('SRC_URI', True) or "").split()，特别是d.getVar('SRC_URI', True)。我不确定到底是什么导致了这个问题。有人愿意帮忙吗？我正在运行 rocko 构建的 yocto。
这是我运行配方时得到的终端输出：
$bitbake nano
