[TEMPLATE] The "<<" operator is not guaranteed to be available for arbitrary types

[gynt]

For example, if a function argument is of type MapperCommandUnion, compilation fails because the compiler cannot find a way to use << on that type.

Steps to reproduce are to define a FunctionResolver instance for a function with non-simple argument types, such as MapperCommandUnion. Then try to compile.

I think it is caused here:

OpenSHC/src/precomp/FunctionResolver.h

Line 219 in 01f9035

#define MACRO_STREAM_PRINT_PARAMETER_LIST(N) MACRO_INDEX_ITERATE_DEPTH_0(N, MACRO_STREAM_PRINT_PARAMETER, << ", ")

First thing:
The error should only happen if the "Wrapper" is active. If this happens otherwise, I need to check the resolver again.

Second:
I am actually aware. There is no default handling for value types that are not primitives or other pointers. C++ has no idea how to print these values and there is no way to automate this.
So, assuming we want to use the resolver method and want to keep the call log option, we would need to define the overloads somewhere.
Since we are not afraid of files, I would say we would create additional C++ files with the overloads for all types that require it.
