Hi all

I'm trying to compile my first carbon program on a iMac using OS9 and
MPW. The code compiles, but the linker complains about unresolved
external references and lists - not really surprizingly - all carbon
API calls I use.

I can compile and run programs using older API's just fine but this is
no option in that the resulting program must run on OS9 and OSX.

How on earth do I teach MPW to link with the carbon library? I'm a
complete newbe when it comes to Mac programing, and I'm currently
bound to using this iMac and OS9. I'm also trying things for quite a
while to no avail... Any help is greatly apreciated!

TIA

Markus

These are the libraries I am linking with:
"{PPCLibraries}"CarbonStdCLib.o, "{PPCLibraries}"StdCRuntime.o,
"{PPCLibraries}"PPCCRuntime.o, "{SharedLibraries}"CarbonLib and
"{SharedLibraries}"StdCLib.

Two runtimes and two StdCLib variants are too much.

You need:
- one runtime (for PPC, StdC was IIRC to produce MPW tools)
- one libaray to access the MacOS routines (CarbonLib)
- one Standard library (only if you use standard C functions like
printf, strcmp et al.)

This set of libraries works for me:
        "{PPCLibraries}StdCRuntime.o"
        "{PPCLibraries}PPCCRuntime.o"
        "{SharedLibraries}CarbonLib"
        "{SharedLibraries}StdCLib"

You could also refer to the Makefiles in the sample code included with
the Carbon SDK (via http://developer.apple.com/sdk/). Some of those
link with {SharedLibraries}CarbonLib alone.

In a project using StdCLib, you must use the following libraries and
objects, in the following order, or your application will not launch
under Carbon (may not properly bind to the OS X StdCLib):

        "{PPCLibraries}CarbonStdCLib.o" ?
        "{PPCLibraries}StdCRuntime.o" ?
        "{PPCLibraries}PPCCRuntime.o" ?
        "{SharedLibraries}CarbonLib" ?
        "{SharedLibraries}StdCLib"
