几个��单的Makefile

Tue, 06 Nov 2012 07:05:00 GMT

几个��单适合��程序的Makefile�Q�可直接拯��使用�Q�自己mark一下，�q�样长时间不用Makefile也不用去看手册了(ji��n)

0.只有一个文�?br />

# 变量的定义，方便使用
CC      = gcc
CCFLAGS = -O2 -s
BIN     = test

BIN     = test
WINDRES = windres
RES     = resource.o
OBJ     = main.o md5.o password.o $(RES)

# where is your mingw library?
LIBPATH = 'C:\Program Files\CodeBlocks\MinGW\lib\'

LIBS=-L$(LIBPATH) -lcomctl32

RM      = -rm

$(BIN): $(OBJ)
    $(CC) $(CCFLAGS) -o $(BIN) $(OBJ) $(LIBS)

main.o: main.cpp

md5.o: md5.cpp md5.h

# �~�译资源文�g
$(RES): resource.rc rpt.ico manifest
    $(WINDRES) -o $(RES) resource.rc

.PHONY:clean
clean:
    $(RM) $(BIN) $(OBJ)

3.�~�译�?r��n)态库
其中一�?<�Q?^, $@是Makefile的自动化变量�Q�详�l�了(ji��n)解可以看《跟我一起写Makefile》的�W�五�?br />

CC = g++

OBJS = utp.o utp_utils.o

# -g : for debug
CFLAGS        = -g -O2 -Wall -DPOSIX
TARGET        = libutp.a

.cpp.o:
    $(CC) -c $(CFLAGS) $<

all: $(TARGET)

libutp.a: $(OBJS)
    ar cru $@ $^
    ranlib $@

.PHONY : clean
clean :
    -rm *.o $(TARGET)

4.�~�译动态库
(0)windows下��用mingw�~�译dll动态库

CC      = g++
OBJS    = utp.o utp_utils.o
CCFLAGS = -fno-exceptions -fno-rtti -Wall -g -lwsock
TARGET = libutp.dll

all: $(TARGET)

   $(CC) -shared -o $(TARGET) $(OBJS) -lws2_32

.cpp.o:
   $(CC) -c -DPOSIX -fpic -I . -I utp_config_lib $(CCFLAGS) $<

.PHONY: clean
clean:
   -rm -f $(OBJS) $(TARGET)

(1)linux下编译so动态库

CC      = g++
OBJS    = utp.o utp_utils.o
CCFLAGS = -fno-exceptions -fno-rtti -Wall -g
TARGET  = libutp.so

all: $(TARGET)

.cpp.o:
    g++ -c -DPOSIX -fpic -I . -I utp_config_lib $(CCFLAGS) $<

.PHONY: clean
clean:
    -rm -f $(OBJS) CCFLAGS

5.�~�译多个目标�Q?-2均是�~�译单个目标
(0) ��d��头文件目�?br />(1) 使用自己�~�译的静(r��n)态库libutp.a

CC          = g++
CFLAGS      = -g
LIBUTP_PATH = /home/actiontec/workspace/code_reading/third_party/libutp/lib
INCLUDES    = -I${LIBUTP_PATH}

把ubuntu配置成�\由器+DHCP

Wed, 22 Aug 2012 14:30:00 GMT

资源�Q?u>

PC A: Ubuntu 12.04 LTS�Q�两块网卡，分别为eth0和eth1�Q��用eth0�q�接互联�|?u>

PC B: Windows 7, 一块网卡，为eth0

目标�Q?u>

使得B通过A�q�接互联�|?IPv4)�Q�即实现A��\由器的功�?u>

步骤�Q?u>

PC A:

(0)假设eth0已经配置好，PC可以通过eth0�q�接互联�|?wbr>�Q�配�|�eth1为，�?etc/network/interface所�C?u>

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

address 172.16.10.65

gateway 172.16.10.254

netmask 255.255.0.0

auto eth1

iface eth1 inet static

address 192.168.6.1

netmask 255.255.255.0

network 192.168.6.0

broadcast 192.168.6.255

当然�Q�我是删除了(ji��n)network-manager,network-manager-gnome的才可以通过配置interface�q�个文�g来设�|�网�l�的

你也可以通过network-manager来配�|�。DNS服务器可以通过/etc/resolv.conf来配�|�：(x��)

nameserver 168.95.1.1 #�q�是我的DNS服务器，你可以配�|�成你可以访问的�Q�如8.8.8.8

重启你的�|�络服务或者重启PC A�Q�以上设�|�就可以生效�?u>

(1)Linux�pȝ��自��n��有IPv4包�{发的功能�Q�在/etc/sysctl.conf�q�行配置�Q?u>

打开IPv4转发功能:

net.ipv4.ip_forward=1

输入以下命��o(h��)使得上面的设�|�生�?或者重启电(sh��)�?�Q?u>

sudo sysctl -p

(2)通过iptable实现IPv4包�{�?u>

sudo iptables -t nat -A POSTROUTING -s 192.168.6.0/24 -o eth0 -j MASQUERADE

可以通过iptables-save��iptables rule都保存到文�g中，在通过iptables-restore��d��rule到iptables中，

可以自己写一个脚本来实现iptables自动的蝲入rule�Q?wbr>或者找到iptables的配�|�文件来修改

PC B

(0)��PC B的eth0与PC A的eth1用网�U�直接连接，配置PC B的eth0为：(x��)

IP ADDRESS : 192.168.6.101

SUBNET MASK: 255.255.255.0

GATE WAY : 192.168.1.1i

DNS Server : 168.95.1.1

�q�样PC B��可以通过PC A�q�接互联�|�了(ji��n)

增强配置�Q?u>

路由器都可以自动�l�PC分配IP�Q�而不需要手动配�|�IP�Q?wbr>�q�是通过DHCP来实现的。如果也要实现相同的功能�Q�那

��需要在PC A上搭��Z��个DHCP服务器�?u>

(0)安装DHCP服务�?u>

sudo apt-get install isc-dhcp-common isc-dhcp-server

(1)配置DHCP

(i)修改/etc/default/isc-dhcp-server

INTERFACES="eth1"

(ii)修改/etc/dhcp/dhcpd.conf

subnet 192.168.6.0 netmask 255.255.255.0 {

range 192.168.6.100 192.168.6.200;

option routers 192.168.6.1;

option broadcast-address 192.168.6.255;

option domain-name-servers 168.95.1.1;

default-lease-time 600;

max-lease-time 7200;

}

(2)PC B可以自动获取IP�?ji��n)，如果在PC A的eth1上接一个switch�Q�接在switch上所有的PC都可以获取IP�?/p>
