cannot compile hello.cs for gtk# using mono command prompt

Question

Had hoped that this would help, but getting a different error.

attempting to compile the following as hello.cs

using Gtk;
using System;
class Hello
{
    static void Main()
    {
        Application.Init();
        Window window = new Window("helloworld");
        window.Show();
        Application.Run();
    }
}

Compiling with the following command "gmcs hello.cs -pkg:gtk-sharp-2.0"

depending on the command prompt, I'm receiving either cs0006 (mono cp) or cs2001 (win cp) saying that files cannot be found from mono cp it says that the metadata file cannot be found from win cp it says that source file cannot be found

Here's a sample:

c:\Users\Stephen Lloyd\Desktop>gmcs hello.cs -pkg:gtk-sharp-2.0
-r:C:/Program Files \(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/pango-sharp.dll \(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/atk-sharp.dll \(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/gdk-sharp.dll \(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/gtk-sharp.dll \(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/glib-sharp.dll  
error CS2001: Source file `Files' could not be found

error CS2001: Source file `\(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/gdk-sharp.dll' could not be found
error CS2001: Source file `\(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/gtk-sharp.dll' could not be found
error CS2001: Source file `\(x86\)/Mono-2.10.8/lib/mono/gtk-sharp-2.0/glib-sharp.dll' could not be found
Compilation failed: 6 error(s), 0 warnings

In all cases the referenced .dlls are in that folder.

Any thoughts?

First thing: please note that the paths given in -r were not properly parsed, you should rather put them around quotation marks. Paste the linux command and output too. — konrad.kruczynski

this was from windows 7 command prompt. 'gmcs hello.cs -pkg:gtk-sharp-2.0' was my only entry. everything else was generated. — Stephen Lloyd

Try to set them manually by -r without using -pkg parameter. — konrad.kruczynski

The weird thing is, this works for me on windows 7, but not on Windows 8. I get the same error as above. I know its not handling the spaces correctly, which boggles my mind because 7 can do it, why can't 8? — FilBot3

-pkg is broken on Windows; you will need to supply individual individual -r[eference]:s. Please see this answer for details.

As an alternative to manually entering references, I found it easier to just install mono to a path with no spaces aka C:\devtools\mono and then adding the ... C:\devtools\mono\bin to your path. The command was then successful for me. As an aside I have had a similar problem before with using unix devtools on windows and this has worked there as well.

Had this problem on MacOSX. The solution to add the mono bin directory to path solved it for me.

Specifically, "/Library/Frameworks/Mono.framework/Versions/Current/bin" needed to be on my path.

I did this:

export MONOPATH=/Library/Frameworks/Mono.framework/Versions/Current
export PATH=${PATH}:${MONOPATH}/bin

And afterwards, I was able to compile via:

gmcs /t:exe /debug+ -pkg:dotnet WinFormsHello.cs

(likewise for gtk# etc)

I was having the same problem running this on Windows 10. Since Windows supports symbolic links, since Vista, I thought this might be a solution ... it worked for me.

As Administrator, I created a directory symbolic link from the root directory to mono:

cd \  
mklink /d mono "\program files x(86)\mono"

Then, again as Administrator, I edited the "Open Mono Command Prompt" shortcut properties:

Target: C:\Windows\SysWOW64\cmd.exe /k "C:\Mono\\bin\setmonopath.bat"  
Start In: C:\Mono

Now when pkg-config parses the drive-path of mono.exe it "sees" only c:\mono and will proceed to append the rest of the path to resolve the required packages.

You can set your symbolic link from any directory. I set it from root for sake of simplicity. The main purpose is to establish a path without spaces or special characters.
