Ah, it is you!
Thanks for the response,
Firstly, it seems to be a bug in the c++ compiler itself ( :( )
Something along these lines :
https://connect.microsoft.com/VisualStudio/feedback/details/362170/function-template-cannot-be-overloaded-by-template-parameter-type
The code is *extremely* primitive, and i am no real stranger to templates.
The confusing thing is the code examples you provided also failed to compile
(after a few hours of blaming my code).
I had a simple class/struct with a single function that i would have like to
expose :
http://pastebin.com/PEwTpWFM
The errors are mentioned in the comments as you can see. If i comment that
line out , it compiles and links just fine. It is a compiler time issues
with the function prototypes,
This also happens in the MyNative ClassBinder demo (deprecated, i know - but
i needed something :) ). Right at the bottom, i have included the line + the
error outputs in full.
It would appear somewhere in the road to templating the compiler adds const
and i have no idea why. I don't want to hack some casts in not understanding
fully.
By far the most informative read on the errors :
http://www.codersource.net/c/c-tutorial-on-templates/c-function-templates-overloading.aspx
:::::::::::: Dump from compiler :::::::::::::
typedef MyNative MY;
w
.BindMemFunc< int, &MY::func1>( "func1" ) <- the exact same error
happens on this line,
Below is the output (spam) from the compiler exact :
