The cl65 compile and link utility may be used to convert, compile, assemble and link files. While the separate tools do just one step, cl65 knows how to build object files from C files (by calling the compiler, then the assembler) and other things.

Most of the options have the same meaning than the corresponding compiler,
assembler or linker option. See the documentation for these tools for an
explanation. If an option is available for more than one of the tools, it
is set for all tools, where it is available. One example for this is -v:
The compiler, the assembler and the linker are all called with the -v
switch.
There are a few remaining options that control the behaviour of cl65:
-SThis option forces cl65 to stop after the assembly step. This means that C files are translated into assembler files, but nothing more is done. Assembler files, object files and libraries given on the command line are ignored.
-cThis options forces cl65 to stop after the assembly step. This means that C and assembler files given on the command line are translated into object files, but there is no link step, and object files and libraries given on the command line are ignored.
-o nameThe -o option is used for the target name in the final step. This causes problems, if the linker will not be called, and there are several input files on the command line. In this case, the name given with -o will be used for all of them, which makes the option pretty useless. You shouldn't use -o when more than one output file is created.
-t sys, --target sysThe default for this option is different from the compiler and linker in the case that the option is missing: While the other tools (compiler, assembler and linker) will use the "none" system settings by default, cl65 will use the C64 as a target system by default. This was chosen since most people seem to use cc65 to develop for the C64.
-Wa options, --asm-args optionsPass options directly to the assembler. This may be used to pass options
that aren't directly supported by cl65. Several options may be separated by
commas, the commas are replaced by spaces when passing them to the
assembler. Beware: Passing arguments directly to the assembler may interfere
with some of the defaults, because cl65 doesn't parse the options passed. So
if cl65 supports an option by itself, do not pass this option to the
assembler by means of the -Wa switch.
-Wl options, --ld-args optionsPass options directly to the linker. This may be used to pass options that
aren't directly supported by cl65. Several options may be separated by
commas, the commas are replaced by spaces when passing them to the linker.
Beware: Passing arguments directly to the linker may interfere with some of
the defaults, because cl65 doesn't parse the options passed. So if cl65
supports an option by itself, do not pass this option to the linker by means
of the -Wl switch.
