install.cobra fails to compile CobraBinding on Mac

[ramon-rocha]

Failed!
$ /Library/Frameworks/Mono.framework/Commands/pkg-config --libs monodevelop
| Package monodevelop was not found in the pkg-config search path.
| Perhaps you should add the directory containing `monodevelop.pc'
| to the PKG_CONFIG_PATH environment variable
| No package 'monodevelop' found

No clue on this one. I have no Mac to test on.

Will need a Mac guinea pig for this issue I think...

Getting the same exact error :(

[ramon-rocha]

I might be able to workaround this issue by using explicit paths for those references. I need to know the full path to the following files on a Mac:

MonoDevelop.Core.dll
MonoDevelop.Ide.dll
gtk-sharp.dll
glib-sharp.dll
atk-sharp.dll

It's probably not the "right" way to fix it but it might work.

This gets past the package issue:

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/Applications/MonoDevelop.app/Contents/MacOS/lib/pkgconfig

install.cobra could do something like:

path = '/Applications/MonoDevelop.app/Contents/MacOS/lib/pkgconfig'
if File.exists(path)
# add the path the environment

But then I get an error past that point...

[charles-esterbrook]

The next error is:

error: Cannot load reference "/Applications/MonoDevelop.app/Contents/MacOS/lib/pkgconfig/../../lib/monodevelop/bin/MonoDevelop.Ide.dll" due to: Could not load file or assembly 'ICSharpCode.NRefactory, Version=0.0.0.0, Culture=neutral, PublicKeyToken=efe927acf176eea2' or one of its dependencies. The system cannot find the file specified.

I tried this, but not help:

export MONO_PATH=$MONO_PATH:/Applications/MonoDevelop.app/Contents/MacOS/lib/monodevelop/bin

I'll try enhancing install.cobra to work that path into a -lib: for Cobra.

[charles-esterbrook]

I got the -lib in there for Cobra and it still bombs:

Starting to run out of ideas... I don't see anything suspicious about ICSharpCode.NRefactory.dll. The file is there and using dump-assembly.cobra, its references look reasonable:

Any ideas?

Thanks for spending some time on this, Charles.

I get this same error on Ubuntu since Cobra switched to "reflection only" loading on Mono with CLR 4. See our email discussion titled: "shared class".

In that email, you suggested I try

export MONO_PATH=/usr/lib/monodevelop/bin

and that worked. Seemingly the same solution does not work on Mac.

You had a couple other suggestions for me to try including adding those assemblies to the GAC or copying them to the current directory. Did you already try those?

[charles-esterbrook]

I've tried both and no luck. I've been pounding on this all night. Was just about to give up, but then decided to double check the MONO_PATH treatment. My code inside install.cobra that set MONO_PATH was not getting called due to a mistake I made in reading the code. I fixed and now the add-in gets installed! Yay!

Wow, my install.cobra has been brutalized. :-) I'll have to work through it tomorrow/Sunday to eliminate junk.

Btw in MonoDevelop I get this error when trying to build a fresh Cobra console project:

Could not find cobra.exe. Try adding its location to your PATH environment variable.

But at the command line I can enter "cobra" and also "cobra -path". Let me know if you want me to fill out a separate issue.

[ramon-rocha]

Woohoo! I'm looking forward to closing this bug!

As for the cobra.exe issue, it might be a regression introduced with the fix for bug #12 or maybe it never worked on Mac to begin with. Here's the relevant commit: e61223a

That error message implies that CobraCore.findCobraExe is returning nil or a zero-length string. Is that expected on your system since it's a dev machine? Can you re-open issue #12 or open a new one to keep this one about compiling the addin itself? Thanks.

[charles-esterbrook]

I've cleaned up install.cobra and sent you the patch.

[ramon-rocha]

Thanks, I will apply it soon.
