Programming

Aside from the fact that MacOS X has been running on Intel processors & other commodity hardware exclusively for years now. The days of Motorola CPUs and special interfaces are loooong gone.

EDIT: According to Wikipedia, Apple discontinued the PowerPC in 2006, focusing on the Intel platform instead.
_types.h is quite similar to Linux' sys/types.h, only it isn't. I've tried replacing one with the other for this code, and it still won't work. And the way the Makefile is written it apparently uses BSDs make, too, which again works quite different that GNU make.

what i would like to say is that the tool is originally made to run under linux,
in order to use it at first, i had to erase some object files (make cleanall) and i changed the malloc.h to sys/malloc.h, and everything was working fine

at some point i wanted to revert it back to linux i changed the header file back to <malloc.h> and everything was ok, but now ...

How did you do that transition? Was the build-system in place before, or was that added on the Mac-side (when importing to Xcode)?

i run it from the Terminal app, i use Xcode mainly as an editor

yes, they had placed the object files in the distribution but that didn t work for due to elf compatibility and stuff like that so i deleted them and i build it from scratch

Well, to me it seems as if Xcode isn't happy with being "just an editor", but instead it tampered with the build system. If you remove the strange targets at the bottom of each Makefile (just below the update target), suddenly make at least tries to build it. It still fails because of some missing declarations, but from a first view they seem to be because of headers not included (strings.h is missing for strcpy, and malloc.h at the wrong location, ...)

However, it seems that those changes might be quite time-intensive, and hard to automate. So you'll have to decide whether to invest the time to clean up the code, or to re-apply your changes to the original code on a Linux machine.

thank you all for your help,
do you know how can i obtain more information about the compilation process how i can diagnose what are the faults ?
thank you again

Googling the error message would help.

Have you started over from unmodified source yet? It's pretty clear you're going to need to.
