Yes, that is half of the reason for those error messages.  The other half is
that his command didn't link the Apple 2's start-up file -- it linked the
C64's file (which does want __RAM_SIZE__, and doesn't create EXEHDR.)!


Scott,
you would need to put _both_ of the "-t" and "-C" options on the command
line:

cl65 -t apple2 -C apple2-tgi.cfg tgidemo.c

cl65 is the tool-chain manager; it runs other programs (depending on what
types of files you have at the start of the command's execution, and what
types you want to have at the end).  In the above example,
cl65 gives the "-t" option to cc65 and ca65; then it gives the "-C" option
to ld65.  Also, cl65 looks at the "-t" option when it chooses which start-up
and library files to link with your program.

If you don't put a "-t" option in a cl65 command-line, then cl65 will assume
that you wanted "-t c64".  It isn't smart enough to figure out what a "-C"
option can imply about "-t".  You must tell it explicitly which
platform-type you want.
