yocto d.getVar schlägt fehl

Question

Learning Yocto von http://book.yoctoprojectbook.com/index. Kapitel 4 hat folgenden Code

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 

Das Rezept befindet sich in Meta-Hallo/Rezepte-Editor/Nano. Im Grunde versucht es, ein nano Text-Editor-Paket zu erstellen. Es ist bei der do_fetch() Task fehlgeschlagen. Nach dem Debugging einiger Druckanweisungen habe ich herausgefunden, dass der Fehler in dieser Zeile auftritt: src_uri = (d.getVar('SRC_URI', True) or "").split(), speziell unter d.getVar('SRC_URI', True). Ich bin nicht wirklich sicher, was genau das Problem verursacht. Möchte jemand helfen? Ich betreibe eine rocko Build von yocto.

Hier ist die Terminal-Ausgabe erhalte ich, wenn ich das Rezept ausführen:

$bitbake nano

Und hier ist die eigentliche Protokolldatei:

Ich bin nicht sicher, was Sie testen, aber wenn ich dieses Beispiel versuchen, scheitert es bei der Analyse mit:

ERROR: ExpansionError during parsing /media/build/poky/meta/recipes-core/base-files/test_1.0.bb
Traceback (most recent call last): File "/media/build/poky/bitbake/lib/bb/data_smart.py", line 412, in DataSmart.expandWithRefs(s='${SITE}/v${PV_MAJOR}.${PV_MINOR}/${PN}-${PV}.tar.gz', varname='SRC_URI'): try: > s = expand_var_regexp.sub(varparse.var_sub, s) try: File "/media/build/poky/bitbake/lib/bb/data_smart.py", line 111, in VariableParse.var_sub(match=<_sre.SRE_Match object; span=(9, 20), match='${PV_MAJOR}'>): else: > var = self.d.getVarFlag(key, "_content") self.references.add(key) File "/media/build/poky/bitbake/lib/bb/data_smart.py", line 794, in DataSmart.getVarFlag(var='PV_MAJOR', flag='_content', expand=True, noweakdefault=False, parsing=False): cachename = var + "[" + flag + "]" > value = self.expand(value, cachename) File "/media/build/poky/bitbake/lib/bb/data_smart.py", line 436, in DataSmart.expand(s="${@bb.data.getVar('PV', d, 1).split('.')[0]}", varname='PV_MAJOR'): def expand(self, s, varname = None): > return self.expandWithRefs(s, varname).value File "/media/build/poky/bitbake/lib/bb/data_smart.py", line 426, in DataSmart.expandWithRefs(s="${@bb.data.getVar('PV', d, 1).split('.')[0]}", varname='PV_MAJOR'): except Exception as exc: > raise ExpansionError(varname, s, exc) from exc bb.data_smart.ExpansionError: Failure expanding variable PV_MAJOR, expression was ${@bb.data.getVar('PV', d, 1).split('.')[0]} which triggered exception AttributeError: module 'bb.data' has no attribute 'getVar'

das ist, weil die bb.data.getVar (‚PV‘, d, 1) d.getV sein muss ar ('PV', wahr). Dieses Rezept kann nicht unter Rocko analysiert werden, also glaube ich nicht, dass du das Rezept läufst, von dem du denkst, dass du es bist?
