Ubuntu : .NET Core 3.1 build error

[deokershesh]

I downloaded .NET Core 3.1 source code, while doing the build.sh on Ubuntu, it reports following errors! There doesn't seem to be good error message to possibly resolve the same. Kindly help to fix the below build issue.

@deokershesh do you need to build 3.1? If you want latest sources, please clone https://github.com/dotnet/runtime instead, where the sources have moved. See
https://github.com/dotnet/runtime/blob/master/docs/workflow/README.md

[deokershesh]

@danmosemsft, Infact I started with the same, please refer #1207 , however I was informed that, its for future .Net Core 5.0 project and if I am looking for .NET Core 3.1 then I should be using https://github.com/dotnet/corefx/tree/release/3.1, which now I am using. I have built .NET Core 3.1 successfully on Windows but Linux/Ubuntu!!

Any help in this regard (Ubuntu build error) would be highly appreciated. Basically, I am working to support Informix database by building .NET Core Provider (replica of System.Data.Odbc customized for Informix).

[danmoseley]

@deokershesh got it. Ok have you checked you have the prerequisites? Try upgrading your relevant packages first.

[deokershesh]

Thanks @danmosemsft, The above link helped and I tried to refresh/install the suggested packages and it worked! Thanks a lot. Now, I need to customize for Informix, hope it will also go smooth like on Windows!

[danmoseley]

@deokershesh sure. Post back how your project goes. Do you plan to share it for others to take advantage of?

[deokershesh]

Yes @danmosemsft, We will host on Nuget. I am able to build Informix .NET Core Provider on Linux as well by the way. Facing some run time issue, yet to investigate in detail. By the way, what's the best tool to debug C#(.cs) files on Linux?

[danmoseley]

VS Code. This may help although it might be out of date-

[deokershesh]

Actually I am using "docker image" (/bin/bash command prompt).

What is in CMakeOutput.log @deokershesh? Also dotnet/corefx#42812 suggests you solved your build problem. Should this issue be closed?
