Fab, I’ll stick with the earlier build. My external mono is still 4.8.1 (32-bit) ! I guess I should really update that so I can double-check these things on internal/external.
Latest external compiler doesn’t work with anymore 4.8?
I’ll try it. I’d try and keep it as per Fire if I’m doing a check like this so I know it’s not a mono thing. Having said that, I just checked and the latest stable mono is more recent than the fire one.
Yeah, you’ll ned to install an external compiler before you can use it 
I know, and I did (I must have removed it some while back), but then I got “Reference ‘libDataAbstract’ could not be resolved for target ‘Toffee-iOS’ (Toffee iOS arm64)”. I noticed it is pointing to “$(Fire.app)/Contents/Resources/Data Abstract/References-Trial/Toffee/iOS/libDataAbstract.fx” , even though the about shows I have DA installed, so I removed it and installed the latest stable DA but it doesn’t seem to have worked and it’s still not resolving (shows N/A in fire). One of those things you start and wish you hadn’t…
Hmm. Do you have DA xml files in ~/Library/Application Support/RemObjects Software/Elements/Reference Paths/Toffee and if so, do they contain valid paths?
That took a while to get it to install the latest DA (all sorts of errors and not seeing terminal open). Anyway, long story short, yes, the external compiler works (with 4.8.1 mono). 
Or should I say it worked once! Now I get Internal error: System.DllNotFoundException: RemObjects.Elements.LLVM.dll
at (wrapper managed-to-native) LLVM.Interop.LLVMInterop:LLVMInitializeX86AsmPrinter ()
at RemObjects.Elements.Toffee.Output.ObjcOutput…cctor () [0x000e1] in :0
I’m guessing this is a mono issue since it did the same in .2469 until I went back to the internal compiler (which works).
If I install the latest mono, 6.6, all is well and working.
