1. Overview
|
||||
-----------
|
||||
<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.
|
||||
|
||||
|
||||
|
||||
2. Basic Usage
|
||||
--------------
|
||||
<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 -v:

||||
The compiler, the assembler and the linker are all called with the -v

3. More usage
|
||||
-------------
|
||||
|
||||
<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.
|
||||
|
||||
- If you don't give a target system on the command line, cl65
|
||||
defaults to the C64.
|
||||
<itemize>
|
||||
|
||||
- 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 you don't give a target system on the command line, cl65
|
||||
defaults to the C64.
|
||||
|
||||
- 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.
|
||||
<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

|

cases, just give the name of your "main" file as first input file.
|
||||
</itemize>
|
||||
|
||||
|
||||
|
||||
4. Examples
|
||||
-----------
|
||||
<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.
