cl65 is the compile & link utility for cc65, the 6502 C compiler. It was
|
|
designed as a smart frontend for the C compiler (cc65), the assembler (ca65)
|
|
and the linker (ld65).

<sect>Overview<p>
|
|
|
|
cl65 is a frontend for cc65, ca65 and ld65. While you may not use the full
|
|
power of the tools when calling them through cl65, most features are
|
|
available, and the use of cl65 is much simpler.
|
|
|
|
|
|
<sect>Basic Usage<p>
|
|
|
|
The cl65 compile and link utility may be used to 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 <tt/-v/:
|
|
The compiler, the assembler and the linker are all called with the <tt/-v/
|
|
switch.
|
|
|
|
There are a few remaining options that control the behaviour of cl65:
|
|
|
|
<descrip>
|
|
|
|
<tag><tt>-S</tt></tag>
|
|
|
|
This 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.
|
|
|
|
|
|
<tag><tt>-c</tt></tag>
|
|
|
|
This 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.
|
|
|
|
|
|
<tag><tt>-o name</tt></tag>
|
|
|
|
The -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.
|
|
|
|
|
|
<tag><tt>-t sys, --target sys</tt></tag>
|
|
|
|
The 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 choosen since most people
|
|
seem to use cc65 to develop for the C64.
|
|
|
|
</descrip>
|
|
|
|
|
|
|
|
<sect>More usage<p>
|
|
|
|
Since cl65 was created to simplify the use of the cc65 development
|
|
package, it tries to be smart about several things.
|
|
|
|
<itemize>
|
|
|
|
<item> If you don't give a target system on the command line, cl65
|
|
defaults to the C64.
|
|
|
|
<item> When linking, cl65 will supply the names of the startup file and
|
|
library for the target system to the linker, so you don't have to do
|
|
that.
|
|
|
|
<item> If the final step is the linker, and the name of the output file was
|
|
not explicitly given, cl65 will use the name of the first input file
|
|
without the extension, provided that the name of this file has an
|
|
extension. So you don't need to name the executable name in most
|
|
cases, just give the name of your "main" file as first input file.
|
|
</itemize>
|
|
|
|
|
|
<sect>Examples<p>
|
|
|
|
The morse trainer software, which consists of one C file (morse.c) and one
|
|
assembler file (irq.s) will need the following separate steps to compile
|
|
into an executable named morse:
|
|
|
|
<tscreen><verb>
|
|
cc65 -g -Oi -t c64 morse.c
|
|
ca65 -g morse.s
|
|
ca65 -g irq.s
|
|
ld65 -t c64 -o morse c64.o morse.o irq.o c64.lib
|
|
</verb></tscreen>
|
|
|
|
When using cl65, this is simplified to
|
|
|
|
<tscreen><verb>
|
|
cl65 -g -Oi morse.c irq.s
|
|
</verb></tscreen>
|
|
|
|
As a general rule, you may use cl65 instead of cc65 at most times,
|
|
especially in makefiles to build object files directly from C files. Use
|
|
|
|
<tscreen><verb>
|
|
.c.o:
|
|
cl65 -g -Oi $<
|
|
</verb></tscreen>
|
|
|
|
to do this.
