yocto - Yocto(Zeus) Perf 构建失败

问题描述

我想在 Yocto（宙斯分支）上构建性能，用于没有 python2 的图像。配方是这个： https ://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-kernel/perf/perf.bb?h=zeus-22.0.4

运行这个配方会产生这个错误：

查看配方，libpython 似乎设置好了？：

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"

为什么它不拿起国旗？

解决方案

PACKAGECONFIGscripting默认情况下包含在其中。

PACKAGECONFIG选项定义如下：

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"。看到这里的第一个逗号了吗？意思是后面定义的是when没有scripting被选中。

因此，如果您不想拉取 python 依赖项，只需将其设置PACKAGECONFIG为一个不包含scripting它的值。

虽然我实际上很惊讶默认没有构建，但这绝对是自动构建器测试的东西。应该是有别的事了吧？
