I can actually install "Successfully", by skipping the testing:
cpanm -n Perl::LanguageServer
However, when using the Perl Extension in VS Code, the first few attempts will fail for not finding modules:
Can't locate MRO/Compat.pm in @INC (you may need to install the MRO::Compat module)
The Perl::LanguageServer starts working as expected, AFTER installing:
cpanm MRO::Compat
cpanm Devel::GlobalDestruction
cpanm Sub::Exporter
But if that is the case, shouldn't those modules be listed as dependencies for Perl::LanguageServer?
I just noticed the note in VS Code extension that "this" isn't supported on Windows. Since the Outline/Code Completion/... seems to work just fine, I assume that "this" is the debugger?
Indeed, when I launch the debugger, I get:
LS: apply_all_roles (Moose::Meta::Class::__ANON__::SERIAL::2=HASH(0x7fffcbcfa798), Perl::LanguageServer::Methods::textDocument, Perl/LanguageServer/Methods/textDocument.pm)
state_dir = /mnt/h/dseynhae/_PERL/corelist/.vscode/perl-lang
initial parsing done, loaded files, parsed 1 files, 1 files
LS: ERROR: Unknow perlmethod _rpcnot_setTraceNotification at /mnt/h/dseynhae/perl5/lib/perl5/Perl/LanguageServer.pm line 217.
The missing modules are not required by the LanguageServer itself. So it's any module that the LanguageServer require that has incorrect dependencies that needs to be fixed.
Basicly LanguageServers run on Windows, but because of issues with Perl and reading stdin in a non blocking way and capturing the output of perl -c in a non blocking way, you might get high CPU load and sometimes the LanguageServer seems to get stuck and will continue after you have made same changes. Because of this basic issues I gave up after spending a lot of time trying to get it working on windows.
Thanks, I'll try to figure out which module has the missing dependencies...
@beltaurus : I haven't played with this module, but give it a try on WSL 2 on Windows, since that's using a virtualized Linux kernel (rather than translating Linux syscalls to Windows syscalls).
As far as I know, trying to get event-driven (non-blocking) code to work on Linux and Windows is a nightmare.
I picked this up where I left off, updating and upgrading my Ubuntu 18.04 LTS WSL distro, and all my the Perl related CPAN modules in my local::lib (Perl::LanguageServer, Perl::Critic, Perl::Tidy,...).
I still have to manually take care of
cpanm --reinstall MRO::Compat
cpanm --reinstall Devel::GlobalDestruction
cpanm --reinstall Sub::Exporter
...UNLESS I execute the Perl::LanguageServer installation with the --notest option!
I made sure I had the latest version of VS Code, and I uninstalled the Perl Debug extension (I don't want any interference with my debugging sessions).
Then I uninstalled and reinstalled the Perl extension.
As long as I don't use multiple workspaces (I'm working in a single folder), I seem to get "decent" behavior from the "Perl::LanguageServer".
My only problem noted so far, is that the debugger output appends a "\n" to my print statements (and the point of my print statements is that there shouldn't be one, until I specify it...
All in all, I'm back to a useable experience, but I think for other users, we should document:
- Install with
--notest(or be prepared to add missing modules, depending on your distro). - Make sure you don't have interference for the Perl debugging sessions.
- There might be issues with print output.
@beltaurus I have also a similar problem to install LanguageServer on Win 10.
Can you please check my issue #52 maybe?

I am seeing this same error on Linux, yet i have the three mentioned missing modules installed already. Anyone know how to fix it?
One of the LanguageServer dependency IO::AIO installation is failing on Win10 with multiple error similar to the following.
AIO.xs: In function 'XS_IO__AIO_pidfd_send_signal': AIO.xs:2678:2: error: unknown type name 'siginfo_t'; did you mean 'eio_ino_t'? siginfo_t si = { 0 }; ^~~~~~~~~
Can someone help?

On Windows 10 WSL2, Ubuntu-20.04.
sudo cpanm Perl::LanguageServer failed on IO:AIO.
perl Makefile.PL failed with error /usr/bin/ld: cannot find -lperl.
The following command fixed the issue and Perl-LanguageServer extension works great.
sudo ln -s /usr/lib/x86_64-linux-gnu/libperl.so.5.30 /usr/lib/x86_64-linux-gnu/libperl.so
I hope this helps.

Following worked for me on Windows 10 WSL2 U20.04 LTS
sudo apt install libanyevent-perl libio-aio-perl
Then cpanm Perl::LanguageServer worked without any errors. And the language server works like a charm.
I just installed Perl::LanguageServer 2.4.0 without any issues on WSL1 (Ubuntu 20.04).
Trying to install it on Ubuntu 18.04 fails, but that is because I don't have a recent enough g++ compiler on that system... The default version 7.5 doesn't understand the -V option required by the Perl Module build instructions... And for some reason, the Perl build instructions ignore my update-alternatives. Since we're just a few months away from Ubuntu 18.04 deprecation, I'm not going to worry about it.
And I consider the initial problem I flagged fixed...
