<sect>Overview<p>
|
||||
|
||||
This document describes how to build your programs using the cc65 development
|
||||
tools and the GNU Make utility.
|
||||
|
||||
The cc65 development package doesn't come with a make utility. However this is
|
||||
no issue because GNU Make works very nicely with cc65.
|
||||
|
||||
|
||||
|
||||
<sect>What is GNU Make?<p>
|
||||
|
||||
GNU Make is a both very powerful and very popular make utility. It might even
|
||||
be called the de facto standard for make utilities. For more information see
|
||||
the GNU Make home page:
|
||||
|
||||
<url url="http://www.gnu.org/software/make/">
|
||||
|
||||
The cc65 development package is available as binaries for several host systems
|
||||
and can easily built for quite some additional systems. The very same is true
|
||||
for GNU Make so a cc65-based project coming with a GNU Make Makefile can easily
|
||||
be built by any cc65 developer no matter what host system is used.
|
||||
|
||||
Because of the strong alignment of the cc65 compiler with the ISO C standard it
|
||||
is very well feasable to compile a single C code base both with the cc65
|
||||
compiler and other C compilers like for example GCC. GNU Make turns out to be
|
||||
very well suited to build projects for several target systems using multiple
|
||||
compilers as it isn't tied to any C compiler.
|
||||
|
||||
|
||||
|
||||
<sect>A sample Makefile<p>
|
||||
|
||||
This Makefile is a fully functional sample for compiling several C sources
|
||||
(here <tt/foo.c/ and <tt/bar.c/) and link the resulting object files into an
|
||||
executable program (here <tt/foobar/):
|
||||
|
||||
<tscreen><verb>
|
||||
SOURCES = foo.c bar.c
|
||||
|
||||
PROGRAM = foobar
|
||||
|
||||
ifdef CC65_TARGET
|
||||
CC = $(CC65_HOME)/bin/cl65
|
||||
CFLAGS = -t $(CC65_TARGET) --create-dep -O
|
||||
LDFLAGS = -t $(CC65_TARGET) -m $(PROGRAM).map
|
||||
else
|
||||
CC = gcc
|
||||
CFLAGS = -MMD -MP -O
|
||||
LDFLAGS = -Wl,-Map,$(PROGRAM).map
|
||||
endif
|
||||
|
||||

ifdef CC65_TARGET
|
||||
define MAKEDEPEND
|
||||
sed -e"s!.s:!.o:!p" -e"s![^\t]*\t\(.*\)!\1:!" < $(<:.c=.u) > $(@:.o=.d)
|
||||
rm -f $(<:.c=.u)
|
||||
endef
|
||||
endif
|
||||
|
||||
.SUFFIXES:
|
||||
.PHONY: all
|
||||
all: $(PROGRAM)
|
||||
|
||||
ifneq ($(MAKECMDGOALS),clean)
|
||||
-include $(SOURCES:.c=.d)
|
||||
endif
|
||||
|
||||
clean:
|
||||
rm -f $(SOURCES:.c=.o) $(SOURCES:.c=.d) $(PROGRAM) $(PROGRAM).map
|
||||
|
||||
%.o: %.c
|
||||
$(CC) -c $(CFLAGS) $< -o $@
|
||||
@$(MAKEDEPEND)
|
||||
|
||||
$(PROGRAM): $(SOURCES:.c=.o)
|
||||
$(CC) $(LDFLAGS) $^ -o $@
|
||||
</verb></tscreen>
|
||||
|
||||
|
||||
<sect1>Invoking the sample Makefile<p>
|
||||
|
||||
Without any specific configuration the sample Makefile will compile and link
|
||||
using GCC. In order to rather use cc65 the variable <tt/CC65_TARGET/ needs to be
|
||||
defined. This may by done as an environment variable or simply as part of the
|
||||
Makefile. However to quickly switch between compilers and/or cc65 targets it is
|
||||
best done on the GNU Make command line like this:
|
||||
|
||||
<tscreen><verb>
|
||||
make CC65_TARGET=c64
|
||||
</verb></tscreen>
|
||||
|
||||
The sample Makefile doesn't require cc65 to be "installed" in any way. Rather it
|
||||
only presumes the single variable <tt/CC65_HOME/ to point to the directory the
|
||||
cc65 packages were unpacked into. Again there are several ways to define this
|
||||
variable but as its value typically won't change often it is best done as an
|
||||
environment variable.
|
||||
|
||||
|
||||
<sect1>Understanding the sample Makefile<p>
|
||||
|
||||
Most parts of the sample Makefile follow the guidlines in the
|
||||
<htmlurl url="http://www.gnu.org/software/make/manual/make.html" name="GNU Make Manual">
|
||||
that can be searched online for background information. The automatic generation of
|
||||
dependency however rather works as described by the GNU Make maintainer Paul D. Smith in
|
||||
<htmlurl url="http://make.paulandlesley.org/autodep.html#advanced" name="Advanced Auto-Dependencies">.
|
||||
|
||||
In the meantime GCC supports this method directly with the preprocessor option
|
||||
<tt/-MP/ while cc65 requires some post-processing of the dependency file with
|
||||
<tt/sed/ adding a second line like in this example:
|
||||
|
||||
<tscreen><verb>
|
||||
foo.o: foo.c foo.h bar.h
|
||||
foo.c foo.h bar.h:
|
||||
</verb></tscreen>
|
||||
|
||||
|
||||
<sect1>Invoking the sample Makefile on Windows<p>
|
||||
|
||||
The recommended way to use GNU Make on Windows is to install it as part of a
|
||||
Cygwin environment. For more information see the Cygwin home page:
|
||||
|
||||
<url url="http://www.cygwin.com/">
|
||||
|
||||
If however installing Cygwin shouldn't be an option for one or the other reason
|
||||
then the sample Makefile may be invoked from the Windows Command Prompt (cmd.exe)
|
||||
by downloading the following programs:
|
||||
|
||||
<itemize>
|
||||
<item>make.exe: <url url="http://gnuwin32.sourceforge.net/packages/make.htm">
|
||||
<item>sed.exe: <url url="http://gnuwin32.sourceforge.net/packages/sed.htm">
|
||||
<item>rm.exe: <url url="http://gnuwin32.sourceforge.net/packages/coreutils.htm">
|
||||
</itemize>
|
||||
|
||||
|
||||
|
||||
<sect>Target-specific Variable Values<p>
|
||||
|
||||
The very limited resources of the cc65 target machines now and then require
|
||||
manual optimization of the build process by compiling individual source files
|
||||
with different compiler options. GNU Make offers
|
||||
<htmlurl url="http://www.gnu.org/software/make/manual/html_node/Target_002dspecific.html" name="Target-specific Variable Values">
|
||||
perfectly suited for doing so. For example placing the code of the two modules
|
||||
<tt/foo/ and <tt/bar/ in the segment <tt/FOOBAR/ can be archived with this
|
||||
target-specific variable definition:
|
||||
|
||||
<tscreen><verb>
|
||||
foo.o bar.o: CFLAGS += --code-name FOOBAR
|
||||
</verb></tscreen>
