This is just a basic starting point for compiling a C project.
TARGET = theapp
SOURCES = $(wildcard *.c)
OBJECTS = $(subst .c$,.o,$(SOURCES))
HEADERS = $(wildcard *.h)
CC = gcc
LINK = gcc
STRIP = strip
$(TARGET): .depend $(OBJECTS)
echo "#define BUILD_HOST \"`hostname -f`\"" > build_host.h
$(LINK) $(LFLAGS) -o $(TARGET) $(OBJECTS) $(LIBPATH) $(LIBS)
$(STRIP) $(TARGET)
.c.o: $*.h common.h
$(CC) -c $(CFLAGS) $(DEBUGFLAGS) $(INCPATH) -o $@ $<
-include .depend
build_host.h:
echo "#define BUILD_HOST \"`hostname -f`\"" > build_host.h
clean:
-rm -f .depend
-rm -f $(OBJECTS)
-rm -f *~ core *.core
-rm -f version.h
-rm -f $(TARGET)
depend:
.depend: Makefile $(SOURCES) $(HEADERS)
@if [ ! -f .depend ]; then touch .depend; fi
@makedepend -Y -f .depend $(SOURCES) 2>/dev/null
test:
echo $(OBJECTS)
How to use build_host.h and generate a version message:
#include "build_host.h" // created by Makefile
void print_version()
{
printf("This is Thingamajig version " VERSION
" built " __DATE__ " " __TIME__ " on " BUILD_HOST);
}
How to do arbitrary conversions with implicit rules:
LOGS = $(wildcard *.log)
LOGPDFS = $(subst .log$,.pdf,$(LOGS))
all: $(LOGPDFS)
%.pdf : %.log
process-log $<
mv output.pdf $@
