Nanopb without callbacks
问题 I'm using Nanopb to try and send protobuf messages from a VxWorks based National Instruments Compact RIO (9025). My cross compilation works great, and I can even send a complete message with data types that don't require extra encoding. What's getting me is the callbacks. My code is cross compiled and called from LabVIEW and the callback based structure of Nanopb seems to break (error out, crash, target reboots, whatever) on the target machine. If I run it without any callbacks it works great
