VERSION CONTROL

SVN (SubVersioN) Install on Debian

Update e.g. >apt-get update Search e.g. >apt-cache search svn Install e.g. >apt-get install subversion

Uninstall e.g. >apt-get remove subversion


VERSION CONTROL

SVN (SubVersioN) Client Command

checkoute.g. >svn co svn://10.132.143.1/truck truck --username=rong

update e.g. >svn update commit e.g. >svn ci a.c –message=“..” add file e.g. >svn add b.c

C Language Compiling, Gcc Make

Why we choose C ? “ The limits of my language are the limits of my

world ” Tranctatus Logico-Philosophicus 5.6 1918

Our Requirements Realize Computer More Control Program Implement not Large but Practical Software Good Support in Multi-fields

Lisp

Script

Shell

Java

To C or Not to C


Assembler

CBest Choice

HISTORY

Birth of C Language Thompson & Ritchie, 1969 ~ 1971 Based on B language

(BCPL, Basic Common Programming language) Rewrite Unix in C, 1973

ANSI (American National Standards Institute) C89 and C99

GNU

What is GNU ? GNU is Not Unix, 1983

Richard M. Stallman (culture legend) Goal: absolutely FREE operating system The GNU Manifesto, 1985 Free Software Foundation (FSF)

Emacs, GCC, tar, … GPL, General Public License

Virus infectivity


COMPILER

GNU Compiler Collection Preprocessor, Assembler, Linker,

Loader, … Support : C, C++, Java, Fortran, Ada,

…

Install on Debiane.g. >apt-get remove build-essential

MAKE

Make Automatically building executable

programs and libraries from source codeaccording to files called “Makefile”

GNU make

BOOK: ”Managing Projects with GNU Make”





MAKEFILE

“Makefile” Specify how to derive the target

program from each of its dependencies

Context The relationship among source files The command used to compile source files

Tools for auto building Makefile makedepend, Imake, autoconf, automake


Tips: disadvantage of make tab and whitespace are different

EXAMPLE


>lsgen_log.c gen_sort.c>makegcc –Wall -I. -O3 gen_log.c -o gen_loggcc –Wall -I. -O3 gen_sort.c -o gen_sort>make cleanrm gen_log gen_sort>make gen_sortgcc –Wall -I. -O3 gen_sort.c -o gen_sort

CC := gccOPT := -O3CFLAGS := -Wall -I. $(OPT)

BINS := gen_log gen_sort

all: $(BINS)

%.o: %.c$(CC) -c -o $@ $^ $(CFLAGS)

clean:rm $(BINS) Makefile
