Hey folks, i got some strange problems with CodeWarrior for freescale's HCS12X family. On various occasions it complains about variable types like "uint8_t" not being defined. As far as i know, uint8_t is required by ANSI-C though as some fixed-size type. Am i plain wrong here or does codewarrior behave strange indeed?? TIA, Florian
CodeWarrior for HCS12X - ANSI-compliant??

It's defined in PE_Types.h (some custom stuff for freescale's Processor Expert) though, which i included. On the other hand, redefining the function as to return byte doesn't do the trick either :-( Greetings, Florian

However, stdint.h is only defined in the ISO C99 standard and not the original ANSI C specification. -- Andrew Smallshaw andrews@sdf.lonestar.org

Funny thing is: it's defined here in PE_Types.h which i included. And the compiler doesn't complain about it the first two dozen times, but after about line 550 it has forgotten about that and several other standard types and #defines :-( Greetings, Florian

I better check that more thoroughly next time. Sorry for the noise Florian

However the various forms of char (un/signed/char) are always available. -- [mail]: Chuck F (cbfalconer at maineline dot net) [page]: <http://cbfalconer.home.att.net> Try the download section. ** Posted from http://www.teranews.com **

Not only makes it more readable, but often a fast way to catch unexplained mystery errors. IDE's are nice, but the problem with having so many of them is that you end up with so many different editors.
