Description Chris Hamons 2017-04-19 20:58:09 UTC
Here is what I have installed (Alpha channel of today):


git clone https://github.com/chamons/Embeddinator-4000/tree/mono_debugging_issue somewhere
git submodule update --recursive --init
cd tests/objc-cli/ && make
open open objcgen/objcgen.sln 
Build solution
Open objcgen run configration and change argument to full path of your testlib bin/Debug 
Open objcgenerator-processor.cs and set a breakpoint at line 101:
			foreach (var mi in t.GetMethods (BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static | BindingFlags.DeclaredOnly)) {
Note you will get a breakpoint at line 154:
		List<Type> enums = new List<Type> ();
with the output containing:

Resolved pending breakpoint at 'objcgenerator-processor.cs:101,1' to void ObjC.ObjCGenerator..ctor () [0x00016].

I get:

Unable to find version '' of package 'Mono.Options'.
Unable to find version '3.6.1' of package 'NUnit'.
Unable to find version '3.6.1' of package 'NUnit.ConsoleRunner'.
Unable to find version '3.5.0' of package 'NUnit.Extension.NUnitV2ResultWriter'.

Looks like I missed a step.

nuget restore generator.sln

should fix that.
Comment 3 Zoltan Varga 2017-04-20 13:47:53 UTC
Thats the command which prints the above errors.
Comment 4 Rodrigo Kumpera 2017-04-21 22:06:28 UTC

Looks like Zoltan is stuck on getting nuget to work.
Comment 5 Zoltan Varga 2017-04-21 23:15:48 UTC
I couldn't reproduce this. With Chris's binaries, the debugger doesn't work, because the .pdb files embed full paths, and if I recompile, I can't reproduce it.
Comment 6 Chris Hamons 2017-04-24 13:55:50 UTC
Yeah, we tried awhile to reproduce this on Zoltan's machine.

I'm out of ideas. :(

I guess I just have to hope it goes away next update.
