I use a fresh cobra-workspace under Windows XP with Mono 2.0 installed.
When I call cobra with a -pkg option it calls pkg-config to get references.
Unfortunately pkg-config returns lots of -r: that don't fit the renamed -ref/-reference option of cobra but cobra thinks of it as a -run/-r option.

I guess it was a bad idea to change the options from "-ref/-r -run" to "-ref/-reference -run/-r".

Maybe I should uninstall my Mono SDK I wanted to use to limit myself to cross platform features ?

Here is the code in the Cobra compiler that implements pkg-config. You can see towards the end that it's looking for "-r:" (not "-ref:") in the output and splitting on that. And the original option text from pkg-config is not being used:

def refsForPackage(pkgName as String) as List<of String>
        """
        Returns the library/DLL refs for the give package name.
        Runs pkg-config to get that list.
        See HowTo/GTK.cobra
        """
        refs = List<of String>()

        # example: pkg-config --libs gtk-sharp-2.0
        p = Process()
        p.startInfo.fileName = 'pkg-config'
        p.startInfo.arguments = '--libs [pkgName]'
        if .verbosity > 1
            print 'Running: [p.startInfo.fileName] [p.startInfo.arguments]'
        output = CobraCore.runAndCaptureAllOutput(p).trim
        if p.exitCode
            _addMessage(SourceException('Cannot locate package "[pkgName]"'))
            print ' $ [p.startInfo.fileName] [p.startInfo.arguments]'
            for line in output.split(c'\n')
                print ' |', line
            return refs

        parts = output.replace('-r:', '${1}').split(c'${1}')  # while Cobra uses -ref:, pkg-config outputs -r:
        for part in parts
            if part.trim <> '', refs.add(part.trim)
        
        return refs

So I'm not sure what the problem is. Does pkg-config on Windows spit out /r: instead of -r:?

Can you post back the exact cobra command you are using and the output? Also, try throwing in a -v for verbose and a -c for compile-only.

Thank you Chuck, the cobra side seems fine !
IMO it boils down to a problem with the C#-Compiler shouting 'CS2007', also given the -pkg: option.
But I still don't know how to solve this.
BTW: Happy new year to all of you ...

I confirmed that Cobra was passing -pkg: onto the C# compiler, and it seemed unnecessary. I took that out and tested with no problems (launching GTK apps on Mac OS X that were compiled with cobra -pkg:...).

Checked in.

Update, try again and let me know how it goes.
