Linux IDE setup

[jonny]

Hello,

I'm new to addon development.
I made my first steps using Visual Studio. But I want to move to Linux for future development, because Linux mint 18.1-KDE (Based on Ubuntu 16.04) is my main OS. I figured out, that I have to compile my addons for .NET 3.5, which is not supported by the current MonoDevelop version. I tried to install MonoDevelop 3.12 using  the wheezy/snapshots/3.12.0 repository, but no success due to dependency issues.

Is there any solution, or will .NET 4.5 work just fine?

[HebaruSan]

I use a normal text editor and xbuild, optionally with a Makefile for packaging if it's something I need to build a lot. (I was not a fan of MonoDevelop's enthusiasm for creating extra files I didn't ask for or need, such as .sln. I'm on Ubuntu 16.10, for what that's worth.)

My csproj file has this, which I think is enough to satisfy the version requirement you mention:

    <TargetFrameworkVersion>v3.5</TargetFrameworkVersion>

I'm able to compile that project without issues, and as far as I know my DLLs have worked fine for everybody that has tried them. I have tried opening and compiling the project in MonoDevelop as well, and that worked fine, so I'm not sure there's a problem here.

I tested your method, compiling a empty class but got 31 errors.

.csproj was generated by MonoDevelop 5.10 , and I changed the target framework version manually

Thanks, I see what you mean now. I checked my installed packages for things that might be relevant. Can you try this?

sudo apt-get install mono-reference-assemblies-3.5

The package description says, "This package contains files required to compile applications against an older version of .NET, using Mono 4.0 or above, which only include the latest version of the class library as-is. This is important for producing apps for wider distribution." Hopefully the package name is the same on your distro if it's based on Ubuntu.

[jonny]

I got the reference-assemblie alrady.  (Same Name, because Linux Mint includes the Ubuntu repositorys)

What Version of mono do you have installed?

I have the same version of mono intalled.

just found this thread:

I will try to install referenceassemblies-pcl as well, when I get home this evening.

I wish you luck, that package doesn't exist on my system.

I'm suspicious of the "4.0.0.0" in this part:

Tool /usr/lib/mono/4.5/mcs.exe execution started with arguments: /noconfig /debug:full /debug+ /optimize- /out:obj/Debug/test.dll MyClass.cs Properties/AssemblyInfo.cs /target:library /define:DEBUG /nostdlib /reference:/usr/lib/mono/gac/System/4.0.0.0__b77a5c561934e089/System.dll /reference:/usr/lib/mono/gac/System.Core/4.0.0.0__b77a5c561934e089/System.Core.dll /warn:4

The equivalent command from my xbuild looks like:

Quote

Tool /usr/lib/mono/4.5/mcs.exe execution started with arguments: /noconfig /debug:pdbonly /optimize+ /out:obj/Release/Astrogator.dll (my project's source files) Properties/AssemblyInfo.cs /target:library /define:TRACE /doc:bin/Release/Astrogator.xml /nostdlib /reference:/usr/lib/mono/2.0/System.dll /reference:/usr/lib/mono/2.0/System.Data.dll /reference:/usr/lib/mono/2.0/System.Xml.dll /reference:KSP_x64_Data/Managed/Assembly-CSharp.dll /reference:KSP_x64_Data/Managed/UnityEngine.dll /reference:KSP_x64_Data/Managed/Assembly-CSharp-firstpass.dll /reference:KSP_x64_Data/Managed/UnityEngine.UI.dll /reference:KSP_x64_Data/Managed/KSPAssets.dll /reference:/usr/lib/mono/2.0/System.Core.dll /reference:/usr/lib/mono/2.0/mscorlib.dll /warn:4

So for whatever reason it's using the DLLs from .NET 2.0. Do you have mono-reference-assemblies-2.0 installed as well? Looking at those two packages in aptitude, the 2.0 assemblies are 16.2 MB while 3.5 is just 387 kB, so maybe 2.0 is needed to compile for 3.5.

[jonny]

I solved the problem.

Because .NET 3.5 shares many libaries with .NET 2.0 I had to install mono-reference-assemblies-2.0 and *-3.5. I'm not sure why this is not listed as a dependency of mono-reference-assemblies-3.5 but it worked just fine.
