Description Marek Habersack 2012-08-20 10:51:09 UTC
If one passes mscorlib as reference when calling mtouch, the compilation fails because of runtime symbols being referenced that do not exist in the MonoTouch runtime:

Undefined symbols for architecture armv7:
  "_mono_reflection_create_unmanaged_type", referenced from:
      wrapper_managed_to_native_System_Reflection_Emit_DerivedType_create_unmanaged_type_System_Type in mscorlib.dll.7.o

it looks as if mtouch loaded mscorlib from the standard Mono profile instead of from the location referenced on its command line.

MonoDevelop projects do not reference mscorlib.dll so the mtouch find out it's a required dependency and adjust it to mscorlib-runtime.dll (the SRE-less version for devices). That logic is (likely) not executed when mscorlib.dll is provided as a reference on the command-line. Good catch :-)
