yocto 使用主机 perl 安装打开嵌入式配方

Question

我正在使用 yocto(莫蒂版)，我发现我尝试为 heimdal ( https://github.com/heimdal/heimdal ) 创建的食谱有问题。在配置期间，它最终使用主机安装的 perl 而不是 perl 构建依赖项。所以它可以在任何安装了 perl 和模块的机器上运行，但我认为这不是 yocto 应该工作的方式(如果我错了请纠正我)。

我猜这是 Heimdal 的 configure.ac 文件中的错误，或者是 autotools 的错误。我对 autotools 不是很了解，想知道是否有人可以证实这一点？这是他们的 configure.ac 的直接链接

https://github.com/heimdal/heimdal/blob/master/configure.ac

当然这也可能是我的食谱中的错误:

inherit autotools

我还使用了开放式嵌入式(莫蒂版本)的默认 perl 配方和这个 json-perl 配方:

DESCRIPTION = "This module is a thin wrapper for JSON::XS-compatible modules with a few \
additional features. All the backend modules convert a Perl data structure \
to a JSON text as of RFC4627 (which we know is obsolete but we still stick \
to; see below for an option to support part of RFC7159) and vice versa. \
This module uses JSON::XS by default, and when JSON::XS is not available, \
this module falls back on JSON::PP, which is in the Perl core since 5.14. \
If JSON::PP is not available either, this module then falls back on \
JSON::backportPP (which is actually JSON::PP in a different .pm file) \
bundled in the same distribution as this module. You can also explicitly \
specify to use Cpanel::JSON::XS, a fork of JSON::XS by Reini Urban."

inherit cpan allarch

BBCLASSEXTEND = "native"

Answer 1

Perl 使用 nativeperl 作为 perl 二进制文件，所以，我想，您应该修补项目的 configure.ac 以使用 AC_PATH_PROG 更改 PERL 变量的值，检查 this

此外，您需要 have

inherit perlnative
