I can help with getting MPLAB-C17 and MPASM talking to one another. Hitech C
does not, to my knowledge, support the MPLINK object file format.

MPLAB-C17 always compiles to objects. What sort of diagnostics are you getting
when you link? Also, are you using MPLAB projects, or are you running directly
from the command line?

A couple of quick pointers which might help:
* symbols in MPASM are private by default. Any ASM symbols which
  you need to address from C code must be declared as public via
  the GLOBAL directive in MPASM.
* Conversely, to address C symbols in MPASM code, the symbols should
  be declared in the ASM file as EXTERN. C symbols are public by default,
  so no additional stuff should be necessary there.
* Make sure you link with the appropriate processor module when using
  MPLAB-C17 objects. E.g., p17c756.o.

Hi all,

I'm trying to link object code in a project with two different sources: a
"BIOS" written in ASM and assembled with Mpasmwin and a program written in
C.

I can assemble to "hex" the ASM code directly to hex, or assemble to object
and then link it with Mplink.

?How can I do to compile the C code to object? I'm trying Hitech and
Microchip compiler demo versions right now, but none of them seems to work.
?Any ideas?

Thanks.
