PICC Command-line Driver
The final step not only involves the link stage, but also code generation of all the p-code files. In
effect, the HI-TECH C PRO for the PIC10/12/16 MCU Family version code generator performs
some of the tasks normally performed by the linker. Any user-specified (non standard) libraries also
need to be passed to the compiler during the final step. This is the incremental build sequence used
by HI-TIDE
If is important to note that the code generator needs to compile all p-code or p-code library files in
the one step. Thus, if the --PASS1 option is not used (or --PRE is not used), all C source files,
and any p-code libraries, must be built together in the one command.
of C source files, an undefined symbol error for _main will be produced by the code generator. If
the file that contains the definition for main() is present, but it is a subset of the C source files
making up a project that is being compiled, the code generator will not be able to see the entire C
program and this will defeat most of the optimization techniques employed by the code generator.
of the above restrictions, for example you cannot have an C function compiled into a p-code library
that is called only from assembler code.
2.2.3 Special Processing
There are several special steps that take place during compilation.
If a compilation is performed, and the source file that contains main() is not present in the list
There may be multi-step compilation methods employed that lead to compiler errors as a result
Compile all modified assembler source files to relocatable object files using the -C driver
option
Compile all p-code and relocatable object files into a single output object file

using a multi-step compilation. The following could be used.
PICC --chip=16F877A --pass1 main.c
PICC --chip=16F877A --pass1 io.c
PICC --chip=16F877A -c mdef.as
PICC --chip=16F877A main.p1 io.p1 mdef.obj sprt.obj c_sb.lpp
a_sb.lib
If using a make system with incremental builds, only those source files that have changed
since the last build need the first compilation step performed again, so not all of the first
three steps need be executed.
