I’m experimenting with getting Acumatica running under Ubuntu Linux using Mono on my portable Linux server. I have ASP.NET working with Apache and the few test .aspx and .cs programs working. I’m currently working my way through the web.config file translating Windows paths to Linux paths. I noticed that Node.js-win is installed under WIndows. My understanding this is used for the Modern UI which isn’t a focus for me right now. Is there any additional Node.js packages used by Acumatica beside the base install that Acumatica checks for even if I don’t have the Modern UI enabled?

I’m hoping the Acumatica developer team that may be lurking here on the forum can respond to my above questions.

My NpmCache doesn’t show any files for the tenant I’m converting nor can NPM be found or used from PowerShell. My assumption at this point installing Node.js v22.19.0 is all that is needed.

I missed these directories in the port to Linux. This explains the Load() / Bad Image error. I may have thrown ANTLR out with the bathwater. I’m ready for another round of lets get a DLL to compile. Maybe page 3 of this thread will be the charm. Yuriy informed me Acumatica's use of ANTLR isn't using Java.

I added the missing directories and changed the path in all the assemby .ini files. I'm still getting an image load error. Not sure where to go from here.

I would love to know what Acumatica sets APPDIR web environment variable to be and is their any other environment variables set? I think I addressed all the config files with hard coded Windows paths as far as I know.

Any suggests are welcome. Knowing ehat is causing the load / bad image error would be helpful.

If the *_0.cs creation issue could be solved, it may resolve the load bad image issue.

Is Acumatica's goal to make the Windows version ASP free before porting it to Linux?

Acumstica Dev Team:

I could use what you have done getting your toolset to run on Linux under .NET Core.

* Web server environment variables used and their content

* Changed Window style paths to Linux files

* Getting the *_0.cs file built for the temporary form DLL. Where does this file get its file structure from?

I will do a writeup how I got this to work so others can try it if the community and dev team chip in. I'm not convinced yet this won't run.

If Acumatica hard codes it's Windows path with its ANTLR code generation that would pretty much kill this effort. I'm hoping Acumatica wouldn't take that shortcut.

I'm getting tired of talking to myself on this forum. There doesn't seem to be any interest in Linux by Acumatica.

Chris,

Can you remove this thread from the forum?

Does Acumatica have a public forum for those interested in Acumatica running on Linux under .NET Core?

This is why my Acumatica on Linux under Mono failed.

Hardcoded to Windows components like IIS and the Windows Registry.

@JSpikowski I think you spend a lot of time on an interesting project.
Acumatica is moving to be a cross platform solution. However, ERP software is very big, so, unfortunately, the change does not happen as fast as some developers would like.

Here are several things that prevent Acumatica from running on Linux:

The Classic UI in Acumatica is based on ASP.Net Web Forms technology which is not included into .Net Core and newer .Net run-times. This dependency bounds Acumatica to .Net Framework.

While the Modern UI is announced for Acumatica 2025 R2, a lot of effort is expected to migrate every customer and update all customizations. So, for some time (I would estimate it in two major releases, but this is just my opinion) there will be a compatibility mode with two UIs available. Only after it is over, the dependency on the Classic UI can be dropped.

I also think that it is highly unlikely that ASP.Net WebForms support in Mono will be enough to run Acumatica as is discussed here. And the goal is the modern .Net runtime, not Mono.
Acumatica uses some of Windows APIs internally for some of its platform features. This means, that even after migration to .Net Core Acumatica won’t run on Linux without further work.
There are some other features that rely on libraries present only for .Net Framework. Acumatica will have to carefully consider which dependencies have to be dropped and which will need a rewrite with some alternative.

As Sergey wrote here, trying to port Acumatica to Linux is a dead end because of this.
