[Mono-ue] Mono for UE build issues

Michael,
thanks for posting workaround. I tried this way:
First, removed the copy of libmonosgen-2.0.dylib and its symlink:
$ rm /usr/local/lib/libmonosgen-2.0.*
Then:
$ pwd
/Users/keinakazawa/Documents/workspace/UnrealEngine
$ install_name_tool -id '@rpath/libmonosgen-2.0.dylib'
Engine/Binaries/ThirdParty/EMono/bin/Mac/libmonosgen-2.0.dylib
$ cp Engine/Binaries/ThirdParty/EMono/bin/Mac/libmonosgen-2.0.dylib
Engine/Plugins/XamarinUE4/MonoRuntime/Source/ThirdParty/mono/lib/Mac/libmonosgen-2.0.dylib
And I switched back to Xcode and performed Cmd+R. But start-up sequence
failed with the same error I got previously:
dyld: can't resolve symbol _mono_set_signal_chaining in
/Users/keinakazawa/Documents/workspace/UnrealEngine/Engine/Plugins/XamarinUE4/MonoRuntime/Binaries/Mac/UE4Editor-MonoRuntime-Mac-Debug.dylib
because dependent dylib #10 could not be loaded
I did a quick survey to know what's going on and to find out quick fix.
$ otool -L
Engine/Plugins/XamarinUE4/MonoRuntime/Binaries/Mac/UE4Editor-MonoRuntime-Mac-Debug.dylib
| grep libmono
/Users/michael/Mono/mono/../build/lib/libmonosgen-2.0.1.dylib
(compatibility version 2.0.0, current version 2.0.0)
So, it seems that changing hard coded libpath inside
UE4Editor-MonoRuntime-Mac-Debug.dylib would just be a workaround.
$ install_name_tool -change
"/Users/michael/Mono/mono/../build/lib/libmonosgen-2.0.1.dylib"
"@rpath/libmonosgen-2.0.dylib"
Engine/Plugins/XamarinUE4/MonoRuntime/Binaries/Mac/UE4Editor-MonoRuntime-Mac-Debug.dylib
$ cp Engine/Binaries/ThirdParty/EMono/bin/Mac/libmonosgen-2.0.dylib
Engine/Plugins/XamarinUE4/MonoRuntime/Binaries/Mac/
After performing this tweak, It's working on my Mac. I still suspect
UE4Editor-MonoRuntime-Mac-Debug.dylib will be replace every time I build,
but putting `install_name_tool` on post-build script doesn't seem to be a
reasonable option..
Or am I missing something? i.e. Do I need to clean & rebuild after
`install_name_tool -id ...` command?
Regards, Kei.
