5 Compile and link utility for cc65
7 (C) Copyright 1998-2000 Ullrich von Bassewitz
32 cl65 is a frontend for cc65, ca65 and ld65. While you may not use the full
33 power of the tools when calling them through cl65, most features are
34 available, and the use of cl65 is much simpler.
41 The cl65 compile and link utility may be used to compile, assemble and
42 link files. While the separate tools do just one step, cl65 knows how to
43 build object files from C files (by calling the compiler, then the
44 assembler) and other things.
46 ---------------------------------------------------------------------------
47 Usage: cl65 [options] file
50 -C name Use linker config file
51 -Cl Make local variables static
52 -D sym[=defn] Define a preprocessor symbol
53 -I dir Set a compiler include directory path
54 -Ln name Create a VICE label file
56 -Oi Optimize code, inline functions
57 -Or Optimize code, honour the register keyword
58 -Os Optimize code, inline known C funtions
59 -S Compile but don't assemble and link
60 -V Print the version number
62 -c Compiler and assemble but don't link
66 -m name Create a map file
67 -o name Name the output file
68 -t sys Set the target system
73 --ansi Strict ANSI mode
74 --asm-include-dir dir Set an assembler include directory
76 --debug-info Add debug info
77 --help Help (this text)
78 --include-dir dir Set a compiler include directory path
79 --target sys Set the target system
80 --version Print the version number
81 --verbose Verbose mode
82 ---------------------------------------------------------------------------
84 Most of the options have the same meaning than the corresponding compiler,
85 assembler or linker option. See the documentation for these tools for an
86 explanation. If an option is available for more than one of the tools, it
87 is set for all tools, where it is available. One example for this is -v:
88 The compiler, the assembler and the linker are all called with the -v
91 There are a few remaining options that control the behaviour of cl65:
95 This option forces cl65 to stop after the assembly step. This means that
96 C files are translated into assembler files, but nothing more is done.
97 Assembler files, object files and libraries given on the command line
103 This options forces cl65 to stop after the assembly step. This means
104 that C and assembler files given on the command line are translated into
105 object files, but there is no link step, and object files and libraries
106 given on the command line are ignored.
111 The -o option is used for the target name in the final step. This causes
112 problems, if the linker will not be called, and there are several input
113 files on the command line. In this case, the name given with -o will be
114 used for all of them, which makes the option pretty useless. You
115 shouldn't use -o when more than one output file is created.
121 The default for this option is different from the compiler and linker in
122 the case that the option is missing: While the compiler and linker will
123 use the "none" system settings by default, cl65 will use the C64 as a
124 target system by default. This was choosen since most people seem to use
125 cc65 to develop for the C64.
132 Since cl65 was created to simplify the use of the cc65 development
133 package, it tries to be smart about several things.
135 - If you don't give a target system on the command line, cl65
138 - When linking, cl65 will supply the names of the startup file and
139 library for the target system to the linker, so you don't have to do
142 - If the final step is the linker, and the name of the output file was
143 not explicitly given, cl65 will use the name of the first input file
144 without the extension, provided that the name of this file has an
145 extension. So you don't need to name the executable name in most
146 cases, just give the name of your "main" file as first input file.
153 The morse trainer software, which consists of one C file (morse.c) and one
154 assembler file (irq.s) will need the following separate steps to compile
155 into an executable named morse:
157 cc65 -g -Oi -t c64 morse.c
160 ld65 -t c64 -o morse c64.o morse.o irq.o c64.lib
162 When using cl65, this is simplified to
164 cl65 -g -Oi morse.c irq.s
167 As a general rule, you may use cl65 instead of cc65 at most times,
168 especially in makefiles to build object files directly from C files. Use
180 If you have problems using the utility, if you find any bugs, or if you're
181 doing something interesting with it, I would be glad to hear from you.
