C# application built with mkbundle doesn't work

Question

I am trying to build this C# program using MkBundle so that users can run it on Linux without having to install Mono.

But I keep getting an error when trying to use the program that is built.

Steps to reproduce:

Git clone this project:

https://github.com/nddipiazza/Sharepoint-Exporter

Extract the DLL's from this:

https://www.microsoft.com/en-us/download/confirmation.aspx?id=35585 -

In Solution explorer, right click References -> Add reference -> Browse .NET assemblies -> Add the Microsoft sharepoint DLLs
- Microsoft.SharePoint.Client.dll
- Microsoft.SharePoint.Client.Runtime.dll
Build the application.

(or alternatively just grab the built application from here https://drive.google.com/a/lucidworks.com/file/d/1GPgkmike9KYTDBGLuNj0R_0Q_FDQdhKr/view?usp=sharing )

Run:

mkbundle --simple --static --deps -o ./SpFetcher bin/Release/SpPrefetchIndexBuilder.exe

Note that the bundle seems to build successfully:

Generated ./SpFetcher

Now run the ./SpFetcher program
- On the machine with Mono, it works fine.
- On a machine without mono, you get this error:
The URI prefix is not recognized. at System.Net.WebRequest.Create (System.Uri requestUri, System.Boolean useUriBase) [0x000ae] in <50d80b08c1a5449282b22aedf03ce925>:0 at System.Net.WebRequest.Create (System.String requestUriString) [0x00014] in <50d80b08c1a5449282b22aedf03ce925>:0 at Microsoft.SharePoint.Client.SPWebRequestExecutor..ctor (Microsoft.SharePoint.Client.ClientRuntimeContext context, System.String requestUrl) [0x0002e] in :0 at Microsoft.SharePoint.Client.DefaultWebRequestExecutorFactory.CreateWebRequestExecutor (Microsoft.SharePoint.Client.ClientRuntimeContext context, System.String requestUrl) [0x00021] in :0 at Microsoft.SharePoint.Client.ClientContext.GetFormDigestInfoPrivate () [0x0000d] in :0 at Microsoft.SharePoint.Client.ClientContext.EnsureFormDigest () [0x0001f] in :0 at Microsoft.SharePoint.Client.ClientContext.ExecuteQuery () [0x00008] in :0 at SpPrefetchIndexBuilder.SpPrefetchIndexBuilder.getSubWebs (System.String url, System.Collections.Generic.Dictionary`2[TKey,TValue] parentWebDict) [0x00266] in <8afd075a89d9457b827aef736e8e1c09>:0 at SpPrefetchIndexBuilder.SpPrefetchIndexBuilder.Main (System.String[] args) [0x00018] in <8afd075a89d9457b827aef736e8e1c09>:0

That error is not expected.

Does the mkbundle program not work correctly?

The c# program I am trying to mkbundle: https://drive.google.com/a/lucidworks.com/file/d/1GPgkmike9KYTDBGLuNj0R_0Q_FDQdhKr/view?usp=sharing

The mkbundled result: https://drive.google.com/file/d/13kHG-RxSqfMFlE53wCSe9iqfwOzheKUm/view?usp=sharing

UPDATE: I have created a ticket on mkbundle issue tracker. https://bugzilla.xamarin.com/show_bug.cgi?id=60753#bug_status_bottom

this looks like a versioning problem; what version of mono has the "machine with mono" and what version of mono was used to run mkbundle? — knocte, Nov 21 '17 at 06:50
Hi @knocte. thanks for the response. I created the bundle using mkbundle, then ran the bundled app on the same machine. so it should be the same version. — Nicholas DiPiazza, Nov 27 '17 at 14:50
still, what version of mono? and how did you install it on your machine? — knocte, Nov 27 '17 at 15:30
I'm on Ubuntu 16. Mono JIT compiler version 5.4.1.6 My project is using .NET 4.6.1 Installed mono using http://www.mono-project.com/download/#download-lin I added the repos then I ran `sudo apt-get install mono-devel` — Nicholas DiPiazza, Nov 27 '17 at 20:03
Can you try another simple program which gets a response from a url? Try to build that and run it and see if it works or not. Also try with and without the Reference to the sharepoint dlls — Tarun Lalwani, Dec 06 '17 at 19:32
@TarunLalwani that didn't help. But found an answer from the committers - answered below. — Nicholas DiPiazza, Jan 02 '18 at 16:18

Got a response from one of the project owners migueldeicaza on the github ticket I created:

This is caused by a missing machine.config file in the bundled executable.

Probably we should make it so that mkbundle ships the machine.config as well, in the meantime use:

mkbundle --simple --deps -o foo a.exe --machine-config /etc/mono/4.5/machine.config And the problem is that without automatic shipping of machine.config, developers will struggle with the cross compiler to find the proper path.

First take a look at the conversation on that ticket I created, then you should know what to change. in my case this works:

MONO_LOG_MASK=asm MONO_LOG_LEVEL=debug mkbundle --simple --static --deps -o ./SpFetcher --config /etc/mono/config --machine-config /etc/mono/4.5/machine.config bin/Release/SpPrefetchIndexBuilder.exe

finally works. i built this against ubuntumate 16, then moved this to a ubuntumate 17 machine with no mono installed, ran it and it passed!
