I am pretty new to mono and C# so this is probably a simple question, but i cannot find the answer.
I need to compile a C# visual studio console application on my mac. I thought mono would be right for that purpose. I don't know which file to compile and took program.cs (where my main function is) or should i compile Project.csproj.
When i run
gmcs Program.cs
I get
Program.cs(17,16): error CS0246: The type or namespace name `Oplossing' could not be found. Are you missing an assembly reference?
Program.cs(129,54): error CS0246: The type or namespace name `Order' could not be found. Are you missing an assembly reference?
What en how should i compile?
Via xbuild, you should be able to compile csproj directly,
http://www.mono-project.com/Microsoft.Build
Unless you are working on a system without a ui, (since you are targetting macos you have a ui) download and install Monodevelop and open the visual studio project with that.
Otherwise check the (g) mcs documentation
The way to use it is already in te comments here
Note: you do NOT have to recompile your app on MacOs to run it on MacOS, just copy the exe (assembly) to your mac and execute it with mono

I need to feed data to Dafny functions and get their output. For that, I am trying to create a C# program that calls the Dafny functions.
As a test I created a very simple Dafny file:
module myDafnyModule {
method boolMethod(b: bool) returns (r:bool) {
return !b;
}
function method boolFunctionMethod(b:bool):bool {
!b
}
}
My main guess is that I should approach this as a multi-file .NET assembly.
For this, I should
generate the C# for the Dafny part of the program with something like dafny /spillTargetCode:1 dafnyModule.dfy
compile that as a module with something like csc /target:module dafnyModule.cs
compile the main C# program with something like csc Main.cs /addmodule:dafnyModule.netmodule.
Step 1 works. However, the csc call in step 2 fails with lots of errors like
$ csc dafnyModule.cs
Microsoft (R) Visual C# Compiler version 3.6.0-4.20224.5 (ec77c100)
Copyright (C) Microsoft Corporation. All rights reserved.
dafnyModule.cs(50,28): error CS0234: The type or namespace name 'Immutable' does not exist in the namespace 'System.Collections' (are you missing an assembly reference?)
dafnyModule.cs(1718,40): error CS0246: The type or namespace name 'BigInteger' could not be found (are you missing a using directive or an assembly reference?)
...
My questions are:
What is missing in the csc call in step 2 to compile the C# code generated by Dafny?
Is this the best way to interface with Dafny code? There are other options I could imagine, though they seem more laborious and error-prone:
have the main entry point in Dafny and have it call C# functions to deal with the input/output?
have a C# program load at runtime the DLL generated by the Dafny compiler?
Actually, I'm not a C# person and I'd prefer to call into Dafny from Java! But I guess Java support is less mature than C# and there's less information. A Java similar question got no answers...
For completeness, I am using Dafny 3.1, dotnet 5.0.104, csc from mono 6.12.0.90 on macOS 11.3.1.
I realized that the Dafny-generated C# code starts with a handful of lines that seem to hint to use dotnet to compile, instead of csc (which I was using because dafny /help mentions it).
Following that thread I found how to build an application with a library using dotnet.
And it worked, just by putting the generated C# code where the library is expected and the main app where it should be.
The whole solution & project thing of dotnet sounds kinda daunting and brings painful flashbacks of Visual Studio on Windows, but it was mercifully straightforward.
I'm attempting to use the following command line command to compile an assembly of the code from my project:
C:/"Program Files"/Unity/Editor/Data/Mono/bin/gmcs
-target:library -out:C:/Users/Austin/Desktop/PixelExpanse.dll
-recurse:C:/Users/Austin/Desktop/Projects/Repos/trunk/PixelExpanse/SpaceColonyRefactor/Assets/Source/*.cs
-d:RUNTIME -r:C:/"Program Files"/Unity/Editor/Data/Managed/UnityEngine.dll
As you can see, I am, I believe, correctly referencing the UnityEngine.dll.
The code that would be compiled contains references to UnityEngine.UI and UnityEngine.EventSystems. But when I run the above command, I get the following compile error:
error CS0234: The type or namespace name 'EventSystems' does not exist in the namespace 'UnityEngine'. Are you missing an assembly reference?
From what I have been able to find through googling, it SEEMS like an error people were getting when using a pre-4.6 assembly, because thats when EventSystems and UI were both introduced. But I don't know how I could be missing that in the dll I'm referencing as Unity 5 is the only version that has ever touched this computer.
As a side note, I have posted this question to Unity Answers and have yet to receive a response. I expect it's because assembly compilation is beyond the scope of what most users there choose to undertake. Hence my asking it here.
The namespace UnityEngine.EventSystems actually appears in UnityEngine.UI.dll and not UnityEngine.dll so it seems you need to reference the former too when compiling manually from the command-line. Unity projects have this by default (see below).
This is verified by opening up the assembly in your reflector tool of choice, here I am using JetBrains dotPeek:
This is how my test project appears with default Unity references. Note that by default a reference to UnityEngine.UI already appears in the Unity-created project:
When I built my Windnows desktop app via Unity, the above dlls appeared in:
<drive>:<projectOutFolder>\<projectName>_Data\Managed
You can try:
right click on "project panel", and after "Reimport All".
It's can be happen due to switch between platforms, e.g. IOS, or Desktop.. thus, folrders are deleted by became unecessary..
Solve for me: Unity 5.2, Win 7, 32bits;
Good luck!
I checked the UnityEngine.dll and the Eventsystems/UI namespace is not included. Despite, there is a dll in Unity5\Editor\Data\UnityExtensions\Unity\GUISystem\UnityEngine.UI.dll which includes these namespaces.
For mac, it's /Applications/Unity/Unity.app/Contents/UnityExtensions/Unity/GUISystem/UnityEngine.UI.dll.
I am trying to run a C# console application on my server which is running Ubuntu Server 12.04. I have installed Mono JIT version 2.10.8.1 (Debian 2.10.8.1-1ubuntu2.2) and additional packages like gmcs and MonoDevelop. The file that I am trying to execute is called Program.cs and when I run the command $gmcs Program.cs I get the following errors:
error CS0234: The type or namspace name 'Tasks' does not exist in the namespace 'system.Threading'. Are you missing assembly reference?
error CS0246: The type or namespace name 'MySql' could not be found. Are you missing a using directive or an assembly reference?
error CS0246: The type or namespace name 'MySqlConnection' could not be found. Are you missing a using directive or an assembly reference?
I have researched into referencing the .dll files for the above namespaces but have not been able to find an answer that is clear. Most forum links suggest that I install mono - trunk, but I want to know if I should uninstall the existing mono package and then install mono-trunk.
I am new to the Unix platform and researching every step of my way. Your help will be much appreciated.
If you are compiling from the command line, you will need to pass the referenced assemblies as a series of /r or /pkg switches, such as:
mcs /r:MySql.Data.dll Program.cs
Obviously you will need to have the required assemblies installed too.
Also note that gmcs is an (old) alias for the .net 2.0 compiler, that's why it doesn't see System.Threading.Tasks (which is a .net 4 feature). See the -sdk switch of mcs.
You should probably install monodevelop to have a user-friendly IDE to help you.
'...are you missing a using directive or an assembly reference?'
I tried the solution in this question Gtk# in monodevelop not working anymore after upgrading to ubuntu 11.10 unity but appears to not work here.
I am running on Mtn Lion with lastest MonoFramework 2.10.10 and MonoDevelop 3.1.1
Any suggestions to get build going? Thanks.
The error message says exactly what you need to do.
Add reference to Gtk# assembly if no one.
Add using Gtk; to your code.
I've downloaded the IKVM sources (http://www.ikvm.net/) from http://sourceforge.net/cvs/?group_id=69637
Now I'm trying to get it to build in Visual Studio 2008 and am stuck. Does anyone know of documentation of how to build the thing, or could even give me pointers?
I've tried opening the ikvm8.sln, which opens all the projects, but trying to build the solution leads to a bunch of "type or namespace could not be found" errors.
As you can probably guess I'm no Visual Studio expert, but rather am used to working with Java in Eclipse.
So again, I'm looking for either: step-by-step instructions or a link to documentation on how to build IKVM in Visual Studio.
Let me know if you need any more info. Thanks for any help!
Edit: I've also tried a manual "MsBuild.exe IKVM8.sln", but also get a bunch of:
JniInterface.cs(30,12): error CS0234: The type or namespace name 'Internal' does not exist in the namespace 'IKVM' (a
re you missing an assembly reference?)
JniInterface.cs(175,38): error CS0246: The type or namespace name 'ClassLoaderWrapper' could not be found (are you mi

Edit #2: I noticed a "ikvm.build" file so I downloaded and ran nant on the folder, which got me a step further. A few things start to build successfully, unfortunately I now get the following error:
ikvm-native-win32:
[mkdir] Creating directory 'C:\Documents and Settings\...\My Documents\ikvm\ikvm\native\Release'.
[cl] Compiling 2 files to 'C:\Documents and Settings\...\My Documents\ikvm\ikvm\native\Release'.
BUILD FAILED
C:\Documents and Settings\...\My Documents\ikvm\ikvm\native\native.build(17,10):
'cl' failed to start.
The system cannot find the file specified
Total time: 0.2 seconds.
Edit #3: OK solved that by putting cl.exe in the path, still getting other errors though. Note this is all for building it on the console e.g. with Nant. Is there no way to get it to build in Visual Studio? That would be sad...
Edit #4: Next step was installing GNU classpath 0.95, and now it looks like I need a specific OpenJDK installation... Linux AMD64?!
[exec] javac: file not found: ..\..\openjdk6-b12\control\build\linux-amd64\gensrc\com\sun\accessibility\internal\resources\accessibility.java
[exec] Usage: javac <options> <source files>
[exec] use -help for a list of possible options
Edit #5: Got an answer from the author. See below or at http://weblog.ikvm.net/CommentView.aspx?guid=7e91b51d-6f84-4485-b61f-ea9e068a5fcf Let's see if it works...
Edit #6 As I feared, next problem: "cannot open windows.h", see separate question here.
Final Edit: Found Solution! After getting the Platform SDK folders in the Lib and Path environment variables, the solution I described below worked for me.
I don't know that this would do it for you but can you try building from the command line?
msbuild ________
I think that's how I built the application due to the same issues.
OK just got the following reply from the author: http://weblog.ikvm.net/CommentView.aspx?guid=7e91b51d-6f84-4485-b61f-ea9e068a5fcf
If you want to build from cvs, you're on your own. However, you can more easily build from source if you use an official release.
If you download ikvm-0.36.0.11.zip, classpath-0.95-stripped.zip and openjdk-b13-stripped.zip from SourceForge (the last two are under the ikvm 0.36.0.5 release) you have all the sources that are needed.
Now you'll have to open a Visual Studio 2008 Command Prompt (i.e. one that has cl.exe and peverify in the path).
Then in the ikvm root directory, do a "nant clean" followed by "nant". That should build the whole project. After you done that, you should be able to build in Visual Studio (debug target only), but you may need to repair the assembly references in the projects (unless you have ikvm installed in c:\ikvm).
Regards,
Jeroen
Edit: After making sure the Platform SDK folders were in the Path and Lib environment variables, this worked for me. Thanks, Jeroen!
This is how I built IKVM 8.1.5717.0 from source. Visual Studio is not required.
Create a folder:
c:\ikvm\
Add the above folder to PATH (e.g. set PATH=%PATH%;c:\ikvm and leave command prompt open for later).
Download:
ikvmsrc-8.1.5717.0.zip (http://www.frijters.net/ikvmsrc-8.1.5717.0.zip)
Unzip and place "ikvm-8.1.5717.0" folder in c:\ikvm\
Download:
openjdk-8u45-b14-stripped.zip (http://www.frijters.net/openjdk-8u45-b14-stripped.zip)
Unzip and place "openjdk-8u45-b14" folder in c:\ikvm\
Download:
Java 8 SDK (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
Install and make sure location is added to path
Download:
NAnt 0.92 (https://sourceforge.net/projects/nant/files/nant/0.92/nant-0.92-bin.zip/download)
Unzip and place "nant-0.92" folder in c:\ikvm\
ICSharpCode.SharpZipLib.dll (http://www.icsharpcode.net/opensource/sharpziplib/Download.aspx)
Place "ICSharpCode.SharpZipLib.dll" in C:\ikvm\ikvm-8.1.5717.0\bin\
Open the following file in a text editor and change the version number:
C:\ikvm\ikvm-8.1.5717.0\CommonAssemblyInfo.cs.in
Using command prompt from earlier, cd to:
C:\ikvm\ikvm-8.1.5717.0\ikvm\
Run:
..\nant-0.92\bin\NAnt.exe
If successful all the binaries will be in:
C:\ikvm\ikvm-8.1.5717.0\bin
