Unable to install on MacOS

I'm running into and issue when installing Omnisharp using the instructions in the readme. The command fails with the following output:

plz help :-) thx

[razzmatazz]

I don't think omnisharp-roslyn server needs dnvm anymore. In addition DNVM has been deprecated in favor of the new dotnet cli UI – see https://github.com/aspnet/dnvm.

This brew tap needs to be updated.. I will take a look at this as I am using it on a mac too albeit I built it from sources myself.

[MadMacMad]

@razzmatazz plz inform us here when you have fixed it... I can not life without autocomplete... many thx

[razzmatazz]

I was looking at it yesterday, and I don't think I have it working yet..

Check out https://github.com/razzmatazz/homebrew-omnisharp-roslyn:

• brew tap razzmatazz/omnisharp-roslyn AND
• brew install omnisharp-mono OR
• brew install omnisharp-netcoreapp

There are two versions of omnisharp on mac os, me myself I am not sure which one is right for .csproj and which one is for .proj/json style projects.

Still figuring out what makes my home-built omnisharp work for me rather than the one from releases page/this tap..

Please tell me if any of these versions (from my repo) work! @MadMacMad @LandonSchropp

[ylluminarious]

Same issue is occurring for me, although I can get $ brew install omnisharp --without-dnvm to "succeed." However, the server has errors when I try to run it after installing it like that and so my Emacs omnisharp plugin is also not working. Here are said errors, obtained by running /usr/local/bin/omnisharp:

[ylluminarious]

@razzmatazz FYI, I installed omnisharp-mono via your repo by first doing $ brew tap razzmatazz/omnisharp-roslyn and then $ brew install omnisharp-mono, but now that I've installed it, how do I use it? I see a /usr/local/Cellar/omnisharp-mono/1.12.0 folder, but the enclosed bin folder is empty and it looks like all of the stuff in libexec is for running a Windows program. Any advice with this?

[razzmatazz]

@ylluminarious – yeah, this bugs me too, actually, I don't know why omnisharp-mono release has no startup script–IMHO there should be a one-liner shell script in distro with something like mono OmniSharp.exe $@ that actually runs omnisharp server but it is not there for some reason. Btw, OmniSharp.exe has Windows PE header and it looks like a Windows executable but it is a .NET binary actually.

ok my plan is to: a) look how omnisharp-node-client selects versions (https://github.com/OmniSharp/omnisharp-node-client/blob/0fa4cfbff6782420057ef731fbf4311fc376061e/lib/helpers/runtime.ts), and if that does not help b) I will ask guys on slack chat

[razzmatazz]

ok, apparently node client (used for the atom editor) uses mono to run OmniSharp.exe on a mac.

however, I wasn't that lucky:

dotnet run OmniSharp.exe doesn't run that much better, complains about missing libhostpolicy.so

this appears to be a can of worms, lets see if we can figure something out with the help of omnisharp server guys

@ylluminarious @LandonSchropp @MadMacMad btw, what clients are you using? emacs, vim? because vscode and atom I think have this figured out automatically?

related issues:

• https://github.com/dotnet/cli/issues/3939 (DllNotFoundException: System.Native when executing RuntimeInformation.IsOSPlatform on mono) – which is kinda strange because my /usr/local/opt/omnisharp-mono/libexec/OmniSharp.exe binary is from omnisharp-mono.tgz distribution(?!)
• https://github.com/OmniSharp/omnisharp-roslyn/issues/600 (System.DllNotFoundException: System.Native) – a comment from @DustinCampbell says that I should "delete System.Runtime.InteropServices.RuntimeInformation.dll from the OmniSharp output"
  • however, this produces the following erroneous output:

    bob@mbp csharptest1 (master)$ mono /usr/local/opt/omnisharp-mono/libexec/OmniSharp.exe
    OmniSharp:
    System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.InteropServices.RuntimeInformation, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

  • btw, this is on mono 4.8
• https://github.com/dotnet/corefx/issues/9012 (Dependency on System.Runtime.InteropServices.RuntimeInformation causes runtime error for apps targeting net451 on *nix systems (i.e. running on Mono))

[DustinCampbell]

Yeah, that's because System.Runtime.InteropServices.RuntimeInformation.dll is in the deps file. The issue with this particular binary is that it is Windows-specific on .NET Framework builds.

What version of mono are you running? The latest version had changed the assembly loader to have special handling around this assembly. https://github.com/mono/mono/blob/mono-4.8.0-branch/mono/metadata/image.c#L1035-L1091

[razzmatazz]

hmm, 4.8, however, the one from mono-project.com, not from brew..

bob@mbp csharptest1 (master)$ mono --version

[DustinCampbell]

That's likely new enough.

[razzmatazz]

btw, this is binary from v1.12 omnisharp-mono.tgz release

I see there is v1.13 already, but probably doesn't matter that much which one of those I use

[DustinCampbell]

What happens if you launch OmniSharp.exe with the --stdio flag?

[razzmatazz]

mkay, that works! shame I didn't try it myself

@DustinCampbell still my questions are:

• shouldn't there be OmniSharp shell script to launch OmniSharp server on unix, using mono in omnisharp-mono.tgz? something like one-liner #!/bin/sh + mono OmniSharp.exe $@?
• there are two versions for a mac (apparently) on distribution page, omnisharp-mono.tgz and omnisharp-osx-x64-netcoreapp1.1.tar.gz. Which one should be recommended for user to install on a mac? What are the criterias for selecting each one? So I could write this on readme of this repo.. plus would be nice to know w.r.t. omnisharp-emacs development..

[DustinCampbell]

Yes, probably. :smile:

omnisharp-mono.tgz is likely the one to use, and it's better to communicate with it over stdio rather than http (which is the default). omnisharp-osx-x64-netcoreapp1.1.tar.gz is a .NET Core standalone version of OmniSharp that has problems with handling .NET Framework .csproj projects. Eventually, the plan is to just do this: https://github.com/omnisharp/omnisharp-roslyn/issues/666.

[ylluminarious]

@razzmatazz Regarding your question about which client I'm using: I'm only using the Emacs one. Thanks for investigating this and providing the extra info. I need omnisharp for my work (lest I use MonoDevelop, lol), so I'm just going to modify omnisharp-server-executable-path to have something like mono /usr/local/opt/omnisharp-mono/libexec/OmniSharp.exe --stdio and see if that works out so that hopefully I can get my development environment in working order again. Thanks.

[sjrmanning]

Hey guys, I've updated the formula to 1.13.0 and removed the outdated dependency on dnvm. It seems to be working fine here on macOS 10.12.4 with mono 4.8.0 installed via brew. Can you try with this new formula and let me know if it works?

[razzmatazz]

@sjrmanning – can you replace -netcoreapp with -mono version on the formula? I think this is how it should be lately.

[sjrmanning]

@razzmatazz The issue with using the -mono version is it then relies on the user using mono /usr/local/opt/omnisharp/libexec/OmniSharp.exe rather than the omnisharp executable installed with the netcoreapp version. But I agree, if we have mono as a dependency it makes sense to use the mono version. It's been a while since I've been using OmniSharp so I'm happy to create some kind of post-install step that makes an alias for the above, but are there any other changes or side-effects you're aware of that I should know or could affect older upgraded installs?

Edit: It seems like this might have issues on macOS. With the -mono version installed mono OmniSharp.exe returns the same System.DllNotFoundException: System.Native error previously mentioned above.

[razzmatazz]

@sjrmanning ok, I propose this:

a) adding a second formula, omnisharp-mono maybe? Like I did in my experiment at https://github.com/razzmatazz/homebrew-omnisharp-roslyn

b) including a bootstrap file in omnisharp-mono.rb formula (or along with it on the repo, I am new to brew), that is basically a two-liner:

    #/bin/sh
    mono /usr/local/opt/omnisharp-mono/libexec/OmniSharp.exe $@

If you don't have time or are not able to test – I can try to do a PR.

This should keep older users able to use the netcoreapp version and still new users would be able to install omnisharp-mono along too.

[MadMacMad]

hello, well I use Sublime Text 3 together with Unity3D on Mac OS X. thx everybody for jumping in...

[sjrmanning]

@razzmatazz We can definitely add another formula, happy to do that, but does mono /usr/local/opt/omnisharp-mono/libexec/OmniSharp.exe currently work for you? See above -- I'm getting this System.DllNotFoundException: System.Native error with the mono version.

@MadMacMad Can you try install again? The new formula should work for your case, but let me know if you still have any issues.

[razzmatazz]

@sjrmanning it does crash for me too, if you just run it w/out any args – it tries to run in http mode then, I think, by default..

but specifying --stdio works (which is what omnisharp-emacs is using, e.g.)

[sjrmanning]

@razzmatazz I've added an omnisharp-mono formula with a simple shell script (couldn't find a cleaner way than what I've got in the formula to do this, but it seems to work anyway). Let me know if it works for you.

[ylluminarious]

@sjrmanning @razzmatazz Thank for the updates and attention to this issue. I just did a fresh install via $ brew install omnisharp/omnisharp-roslyn/omnisharp-mono and was then able to run $ omnisharp --stdio -s ~/some/dir/my.sln without any failures or warnings. Additionally, I was able to set omnisharp-server-executable-path to "/usr/local/bin/omnisharp" in Emacs and C# auto-completion has been working again. Thanks a lot!

[razzmatazz]

@ylluminarious – I think we can close this issue, works for me too.

[ylluminarious]

@razzmatazz Fine by me.

[LandonSchropp]

Works for me as well! Thanks guys.

[LandonSchropp]

If you guys wouldn't mind, it would be great to see the readme updated with the new instructions for getting things set up with the omnisharp-mono package.

[razzmatazz]

@LandonSchropp – I think this information is client/editor specific..

[sjrmanning]

Going to mark this closed now. I've updated the README to recommend omnisharp-mono as it looks like the .NET Core version will eventually be dropped. Thanks for your help everyone!

[ghost]

Hi I keep getting Error: Calling <<-EOS.undent is disabled! Use <<~EOS instead. /usr/local/Homebrew/Library/Taps/omnisharp/homebrew-omnisharp-roslyn/omnisharp-mono.rb:18:ininstall'

what is going on?

[ylluminarious]

@FireAntJoe Homebrew has removed yet another API used in their formulas. They are doing this quite a lot lately; I suppose they hope it will make people's code cleaner, but it's really serving to break lots of stuff. Anyway, this formula is no longer updated. If you're using the Emacs plugin, you should probably use omnisharp-install-server instead of this formula.

[ghost]

@ylluminarious thank you for the information.

[ylluminarious]

@FireAntJoe It seems that omnisharp-vim has specific instructions for installing the server. They seem to do the same thing as Emacs, except that the extraction and path-setting is done manually. Perhaps you could write a vim function to do it automatically and contribute it to omnisharp-vim? Here is the implementation of omnisharp-install-server if you need some pointers on how to do it.

[ghost]

@ylluminarious no thank you, I stay out of that stuff for a reason lol.

[ylluminarious]

@FireAntJoe Ok, no problem.
