Greetings

I have some old C code that I used to create IDL external routines in
Mac OS 8 and 9. Now that IDL runs under Mac OS X using X11, I want
to convert them. While my C and IDL programming skills are OK, my
application environment skills for C and unix are weak to
non-existent. I just don't have the time to learn them properly and
there are long long time gaps between when I actually do programming.
(This is why I have use IDL in the first place, because it is fast to
get a program working.) When I compiled them years ago using
CodeWarrior IDE, I spent about 3% writing the program, 75% just geting
CodeWarrior environment set and the remaining 22% debugging. This is
hyperboli but it felt like it. I also spent a considerable amount of
time creating pseudo-mechanism for passing multidimensional arrays
back and forth.

My particular problem at the moment is that I know next to nothing
about using the project manager on Mac OS X and only a little Unix. I
always get hung up on getting paths, etc. set correctly in the shell
configuration files. Is there a dummy-type book that will walk one
through making C routine using the development tools that come with
Mac OS X? Also, are there any examples I could download where Mac OS
X is used to see which flag etc need to be set? I already own the
David Fanning's and Ron Kling's books. (I just have to find where I
left them.)

Thanks
