'ant' build file for HelloWorldServlet and JettyLauncher

mikewilsonuk (Mike Wilson) — Sat, 02 Jun 2007 11:15:45 GMT

A pretty straightforward 'ant' build file. You will need to edit the jetty.home property to indicate where you installed Jetty.

Automated GNU Makefile

scvalex (Alexandru Scvortov) — Wed, 02 May 2007 17:43:36 GMT

A simple automated GNU Makefile to build and link c/c++/asm projects. All the variables that need to be tweaked are located at the begining:
PROGNAME: the name of the executable to be built
CC: the C compiler
CPP: the C++ compiler
ASM: the assambler
LD: the linker

This searches for all *.c, *.cpp and *.s files and compiles them into objects. It then links all the files into a single executable.

The strip rule is used to strip all unwanted symbols from the resulting executable. This usually results in a significant (think 40%) size optimisation.



$(VERBOSE).SILENT:



PROGNAME = prog



CC = gcc

CC += -c

CPP = g++

CPP += -c

ASM = nasm

ASM += -f elf -d ELF_TYPE

LD = g++



OBJFILES = $(patsubst %.c,%.o,$(wildcard *.c))

OBJFILES += $(patsubst %.s,%.o,$(wildcard *.s))

OBJFILES += $(patsubst %.cpp,%.o,$(wildcard *.cpp))



all: $(PROGNAME)



clean:

	@echo "Cleaning object files"

	@echo "    rm -f     *.o"

	rm -f *.o

	@echo "Cleaning backups"

	@echo "    rm -f     *~"

	rm -f *~

	@echo "Removing programme"

	@echo "    rm -f     "$(PROGNAME)

	rm -f $(PROGNAME)



%.o: %.s

	@echo "Assambling "$@

	@echo "    ASM       "$<

	$(ASM) $<



%.o: %.c

	@echo "Compiling "$@

	@echo "    CC        "$<

	$(CC) $<

	@echo "    LD        -o "$(PROGNAME)"        "$(OBJFILES)

	$(LD) -o $(PROGNAME) $(OBJFILES)



strip: $(PROGNAME)

	echo -n "Size of "$(PROGNAME)" before strip is "

	strip $(PROGNAME)

	echo -n "Size of "$(PROGNAME)" after strip is "

Basic ant script with vim & jikes

mikewilsonuk (Mike Wilson) — Fri, 19 May 2006 19:39:56 GMT

Apache ant build XML. This will use jikes in place of javac. Any compiler error output is formatted so that vim can parse it.

ant is a modern alternative to make. The build script is an XML file. It works particularly well with java. Download it for free from the Apache ant site. Most people find ant a lot nicer to live with than make.

Ant 101

JohnMunsch (John Munsch) — Tue, 28 Feb 2006 20:31:24 GMT

// Ah Ant. How I love thee, how much better a build tool
// than my ex build tool Make.
//
// This is my current starting build.xml Ant script for any
// Java project. It specifies my usual directories, it will
// build source code, make a Jar, build a War, clean up build
// products, create Javadoc, and even run unit tests.
//
// Notice that I use the JReleaseInfo library to automatically
// generate a Java class that contains version numbers, build
// numbers, etc. Be sure to put the Jar from that library in
// the library directory to get that feature:
// http://jreleaseinfo.sourceforge.net/
