mpu.exe with mono on OSX: System.Exception: Compiler failed to produce the assembly. Output: ''

[internetcoffeephone]

I'm getting some undefinable errors when trying to generate a serializer for an extremely trivial enum, using OSX. Going to try on Windows later.
The command I'm using is
mono mpu.exe -s /Users/xxxx/Desktop/mpack/xxxx.cs

Full error log:

EDIT: Works just fine on Windows. Probably some mono bug?

Sorry for delay.I cannot repro it with Mono 4.0.3 in MacOS X. Please retry it with latest mpu.exe and mono.

Close because this was not reproduced and no additional post... Please reopen when you face this problem again.

i have faced this problem again...

[yfakariya]

Would you tell me the mono version?

[ljdong-fy]

I have fixed it, this problem appeared because i have used "Class a" extends "Class b", and i serialize a but not serialize b, sorry to disturb you.

[yfakariya]

No problem!

Close this because it was not a msgpack issue.
