[Proj] Use of C++

[Kristian Evers]

Janne,

Your argument isn’t very strong without at least mentioning a few specific cases where C++ is not available. I have previously looked into this area and from what I could understand at the time it is mostly a myth that you can’t use C++ on embedded systems. Please elaborate so we can make an enlightened decision.

Hello,


there are very many platforms at the lower level MCU's which mainly use standard c and avoid using c++ ... just to keep it simple and easy! - I don't want to start listing them here ... they are just too many .. all MCU's usually have assembler or c programming environment but seldom c++ is used or either easy available

Transition to c++ would just add problems later! I have been programming c++ since 1995 and I still find it as a rather stupid platform that just adds problems - to switch back to lower level if required for example - At the moment I would rather hang the guy who invented the whole problem (c++) at the first place! All it usually does, it makes programs harder to follow and read and especially to port to lower level targets .. which is often required and desired in real World projects.

Janne,

Can you give specific examples of these platforms that only support C that you think PROJ should be supporting?

Hello,

I think that if you want to keep proj. downwards compatible with C (and
C++) then you should keep it standard C. If you use c++ in the library
NOT any "just C" compiler can ever compile it. So as proj. is so small
library I would keep it standard c since nobody really cares if it is c
or c++ - and anybody can write it to c++ or whatever in very small time
- that is not a problem.

So to be able to use proj. in as many targets as possible, also in
smaller devices like hand held devices or so ... I would strongly
recommend to keep it standard c for ever! - But when that is now said
... they most likely do everything else but what is wanted!? haha! (y)

Janne.
