Question

Bitbake 1.43.0版不能像bitbake用户手册所示的helloworld演示一样工作。

我跳回到了bitbake版本1.23.0，它运行良好。但是，我无法在最新版本上使用它。 ....

base.bbclass

`addtask build'

.bblayer.conf

BBLAYERS ?= " \
    /home/bubba/mylayer/ \
    "

bitbake.conf

TMPDIR  = "${TOPDIR}/tmp"
CACHE   = "${TMPDIR}/cache"
STAMP   = "${TMPDIR}/stamps"
T       = "${TMPDIR}/work"
B       = "${TMPDIR}"

printhello.bb 它位于另一个名为mylayer的目录中

DESCRIPTION = "Prints Hello World"
PN = 'printhello'
PV = '1'

python do_build() {
    bb.plain("********************");
    bb.plain("*                  *");
    bb.plain("*  Hello, World!   *");
    bb.plain("*                  *");
    bb.plain("********************");
}

layer.conf 该文件位于mylayer / conf目录中

BBPATH .= ":${LAYERDIR}"

BBFILES += "${LAYERDIR}/*.bb"

BBFILE_COLLECTIONS += "mylayer"
BBFILE_PATTERN_mylayer := "^${LAYERDIR_RE}/"

我执行bitbake printhello后打印的错误

bubba@bubbaMini:~/hello$ bitbake printhello

我不确定为什么它在一个版本而不是另一个版本上失败。如果有人能解释我做错了什么或我错过了哪一步，那么

Answer 1

当bitbake没有正确设置目录路径时，此错误。

在linux上，运行export PATH=/path-to-bitbake-bin:$PATH

Bitbake版本1.43.0是否损坏？它无法在yocot页上成功运行helloworld演示
