Yocto(Zeus)性能构建失败 [英] Yocto(Zeus) Perf Build fails

问题描述

我想在Yocto(Zeus分支)上构建perf，以获取没有python2的图像.食谱是这样的:

I want to build perf on Yocto (Zeus branch), for an image without python2. The recipe is this one: https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-kernel/perf/perf.bb?h=zeus-22.0.4

运行此配方会产生此错误:

Running this recipe yields this error:

看看食谱，似乎设置了libpython?:

Looking at the recipe, libpython seems to be set?:

PACKAGECONFIG ??= "scripting tui libunwind"
PACKAGECONFIG[dwarf] = ",NO_DWARF=1"
PACKAGECONFIG[scripting] = ",NO_LIBPERL=1 NO_LIBPYTHON=1,perl python3"
# gui support was added with kernel 3.6.35
# since 3.10 libnewt was replaced by slang
# to cover a wide range of kernel we add both dependencies
PACKAGECONFIG[tui] = ",NO_NEWT=1,libnewt slang"
PACKAGECONFIG[libunwind] = ",NO_LIBUNWIND=1 NO_LIBDW_DWARF_UNWIND=1,libunwind"
PACKAGECONFIG[libnuma] = ",NO_LIBNUMA=1"
PACKAGECONFIG[systemtap] = ",NO_SDT=1,systemtap"
PACKAGECONFIG[jvmti] = ",NO_JVMTI=1"
# libaudit support would need scripting to be enabled
PACKAGECONFIG[audit] = ",NO_LIBAUDIT=1,audit"
PACKAGECONFIG[manpages] = ",,xmlto-native asciidoc-native"

为什么不拿起旗帜?

推荐答案

PACKAGECONFIG 默认具有 scripting .

PACKAGECONFIG 选项的定义如下:

PACKAGECONFIG[f1] = "--with-f1, \
                     --without-f1, \
                     build-deps-for-f1, \
                     runtime-deps-for-f1, \
                     runtime-recommends-for-f1, \
                     packageconfig-conflicts-for-f1 \
                     "

PACKAGECONFIG [scripting] 设置为，NO_LIBPERL = 1 NO_LIBPYTHON = 1，perl python3" .在这里看到第一个逗号?这意味着在之后定义的是未选择脚本时的.

PACKAGECONFIG[scripting] is set to ",NO_LIBPERL=1 NO_LIBPYTHON=1,perl python3". See the first comma here? It means that what is defined after is when scripting is not selected.

因此，如果您不希望提取python依赖项，只需将 PACKAGECONFIG 设置为其中没有 scripting 的值.

So if you do not want python dependency to be pulled, just set PACKAGECONFIG to a value without scripting in it.

尽管实际上我很惊讶默认值没有建立，但这绝对是由自动构建器测试过的.可能还有其他情况吗?

Though I'm actually surprised the default does not build, that's definitely something that is tested by autobuilders. There's probably something else going on?
