问题描述
伙计们，我尝试从Scratch 10.2.0用Linux构建gcc。
我严格按照说明进行操作，但是make命令引发以下错误：

也许有人可以帮助我。 如果您需要任何其他信息，请随时询问。
解决方法
您似乎要构建的软件包（ ahem configure）已损坏。
这种情况有时会发生，因为几乎不可能检查所有可能的依赖关系是否正确构建。倒霉！
因此，编译器告诉您无法理解文件/usr/share/texinfo/Texinfo/ParserNonXS.pm
您在这里有两个选择：
- 您发现配置开关需要texinfo并将其禁用（类似于
./configure blablabla --disable-texinfo） - 您可以通过手动编辑文件
/usr/share/texinfo/Texinfo/ParserNonXS.pm并在第5205行添加丢失的行my $lineWnr来修复文件$(".some-class").addClass("another-class");。这可能是Perl脚本，因此此处需要一些perl知识才能破译文件。
由于您正在执行LFS构建，因此我想您的Texinfo软件包应该与您的GCC软件包所期望的软件包匹配。旧的GCC需要旧的texinfo软件包，而较新的GCC需要新的texinfo软件包。如果没有texinfo，则应首先安装它。
,此：
[...]全局符号“ $ lineWnr”要求在/usr/share/texinfo/Texinfo/ParserNonXS.pm第5205行中有显式的软件包名称（您是否忘记声明“ my $ lineWnr”？）。
...似乎是来自Perl的错误消息。这样，您的texinfo版本就与用于运行它的Perl版本不兼容。这可能是因为texinfo软件包太旧或Perl太新，或者可能是因为texinfo软件包在安装时未正确配置。
