ANSI compliant

[kdoney]

I was told by Microchip that I couldn't use your compiler with any of their libraries. The tcpip stack, the usb stack, the advanced graphic stack is all created with code which will not compile with ccs compiler. When I asked if their code and compiler were ANSI standard, they said yes. How can 2 ansi compatible compilers, with standard coding, be incapable of compiling the same program?

Very easily.
The same applies between PC ANSI compilers, especially when you start to work down at the hardware level.

Code is dependant not only on the compiler 'rules', but also on libraries used, and assumptions made by the author. ANSI, makes it _easier_ to transport code between compilers, but customisation _will_ still be needed, for anything beyond the basic 'hello world' type program.
It is like two people reading a book written in English. One a mathematician, and one a psychiatrist. Though both are using the same 'language', the assumptions made by the former, if a 'mod' is referred to, may be very different from those of the latter.

At the very least, you need to have the initialisation headers different for the two compilers, and for CCS, include name definitions for the internal registers. Then, since both compilers contain keywords beyond the ANSI 'standard', which may have different definitions, or not exist at all in the other, you need to check for every single one of these, and either add the definitions, change the syntax, or change the name itself (if it clashes with an internal function).

Where did you get the idea that CCS is "ANSI standard" ?

It is not. It is "C-like", but much is not "standard".

Please correct if this is wrong

I don't mind a superset of names and functions as long as the conventions of the standards are maintained within the additions. When compiler directives no longer utilize the same tokens, it seems as if the "errors" were done on purpose. If I want to use the best library for advanced graphics, tcpip or usb, I need to spend $2000 for the range of Microchip compilers.
