How to cpan install from a local source [Linux::Inotify2]

Question

Trying to install Linux::Inotify on Fedora Core 6 x86 machine which ends up in failure.

Looks like the kernel which is below 2.6.36 doesn't support IN_EXCL_UNLINK. This causes the issue in installation. So I have modified the source code and tried to install. But cpan again replaces it with online repo.

Running make test
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/00_load.t ..... Undefined subroutine &Linux::Inotify2::IN_EXCL_UNLINK called at /root/.cpan/build/Linux-Inotify2-2.1/blib/lib/Linux/Inotify2.pm line 431.

Is there a way to fix this one or install using CPAN local source?

Note: make install using source code is working fine after editing the source code.

Yes you could for example create a local patch that you apply to `Inotify2.pm` before you run `perl Makefile.PL`. Please also [notify the author](https://rt.cpan.org/Dist/Display.html?Name=Linux-Inotify2) of the module about this issue, maybe they will provide a fix in the future — Håkon Hægland, Jul 12 '19 at 07:39
"*make install using source code is working fine*" - then it is already installed. — melpomene, Jul 12 '19 at 07:40
Fedora Core 6 reached end of life in 2007! It hasn't had a security update in over a decade! Upgrade the OS as soon as possible! — Quentin, Jul 12 '19 at 09:43

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

It sounds like you've already done this, so you've already installed it. cpan won't replace it (if it sees the installed version (which it will, unless you used the wrong perl, or unless you used env var PERL_MB_OPT to tell ExtUtils::MakeMaker to install the module in a non-standard location and didn't tell CPAN via env var PERL5LIB)).

`cpanm --look Linux::Inotify2` also may be useful as the first steps here. — Grinnz, Jul 12 '19 at 16:19

install using CPAN local source?

cpanm supports installing from a local tarball (containing the patched sources), see synopsis:

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