Question

尝试在失败的Fedora Core 6 x86计算机上安装Linux :: Inotify。

看起来低于2.6.36的内核不支持IN_EXCL_UNLINK。这会导致安装问题。因此，我修改了源代码并尝试安装。但是cpan再次将其替换为在线仓库。

是否可以解决此问题或使用CPAN本地源进行安装？

注意：编辑源代码后，使用源代码进行安装即可正常工作。

Answer 1

wget https://cpan.metacpan.org/authors/id/M/ML/MLEHMANN/Linux-Inotify2-2.1.tar.gz
tar xzf Linux-Inotify2-2.1.tar.gz
cd Linux-Inotify2-2.1
...apply change...
perl Makefile.PL
make test
make install

听起来您已经完成了此操作，所以您已经安装了它。 cpan不会替换它（如果它看到已安装的版本（除非您使用了错误的perl，或者除非您使用env var PERL_MB_OPT告诉ExtUtils :: MakeMaker，否则它将替换该版本）。将该模块安装在非标准位置，并且没有通过env var PERL5LIB）告诉CPAN。

使用CPAN本地源进行安装吗？

cpanm支持从本地tarball（包含修补的源代码）进行安装，请参见synopsis：

cpanm ~/dists/MyCompany-Enterprise-1.00.tar.gz   # install from a local file

如何从本地来源进行cpan安装[Linux :: Inotify2]
