hello_module.ko with linux2.6.38 gcc and arm-linux-gcc

環境 ubuntu 11.04kernel : 2.6.38-8-generic

專案開發工具: kscope

hello_c_code:

製作 Makefile

#CC= $(CROSS_COMPILE)gcc

#CROSS_COMPILE ?=~/toolschain/4.5.1/bin/arm-linux-

#EXTRA_CFLAGS += -I$(KERNELDIR)/include

ifneq ($(KERNELRELEASE),)

# call from kernel build system

#~/ARM/toolschain/4.5.1/bin

obj-m := hello.o

#/lib/modules/$(shell uname -r)/build

#~/linux-2.6.38

else

#KERNELDIR := ~/linux-2.6.38

KERNELDIR := /lib/modules/$(shell uname -r)/build

PWD := $(shell pwd)

modules:

#$(MAKE) -C $(KERNELDIR) M=$(PWD) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) modules

$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

modules_install:

# $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install

clean:

rm -rf *.o *.ko *~ core .depend *.mod.c .*.cmd .tmp_versions .*.o.d

endif

make 即可後產生 .ko .mod.o .mod.c ... etc

arm 版本

下載 kernel 2.6.38

arm-tool chain : arm-linux-gcc-4.5.1-v6-vfp-20101103 (code_sourcery)

step1:

cd ~/linux 2.6.38

step2:

make oldconfig or make 00xx.config

step3:

make prepare

make scripts

step4:

export PATH=~/ARM/toolschain/4.5.1/bin

step5:

make ARCH=arm CROSS_COMPILE=~/ARM/toolschain/4.51/bin/arm-linux-

ubuntu gcc 4.4.3 降級 gcc 4.3

1、安装gcc-4.3
$ sudo apt-get install gcc-4.3 g++-4.3
2、修gcc相关链接
$ cd /usr/bin
$sudo ln -snf gcc-4.3 gcc
$sudo ln -snf g++-4.3 g++
$sudo ln -snf cpp-4.3 cpp
3、如是64bit系统，则还需装如下包。

Fedora 9設置nfs

以 root 身份登录Fedora9，在命令行运行：
#gedit /etc/exports
编辑nfs 服务的配置文件(注意：第一次打开时该文件是空的)，添加以下内容：
/opt/abc/123 *(rw,sync,no_root_squash)
其中：
/opt/abc/123 表示将要共享的的目录，它可以作
为开发板的根文件系统通过nfs 挂接；
* 表示所有的客户机都可以挂接此目录
rw 表示挂接此目录的客户机对该目录有读写的权力
no_root_squash 表示允许挂接此目录的客户机享有该主机的root 身份

，但默认安装的Fedora 系统开启了防火墙，这会导致NFS 服务
无法正常使用。因此先关闭防火墙，在命令行输入“lokkit”命令
选择其中(*)Disabled，然后选择“OK”退出，这样就永久的关闭了防火墙。
下面是启动 NFS 服务的方法和步骤：

(1)通过命令启动和停止nfs 服务
在命令行下运行：
#/etc/init.d/nfs start

这将启动nfs 服务，可以输入以下命令检验nfs 该服务是否启动。
# mount -t nfs localhost:/opt/abc/123 /mnt/
如果没有出现错误信息，您将可以浏览到/mnt 目录中的内容和
/opt/FriendlyARM/mini6410/root_qtopia_qt4 是一致的。
使用这个命令可以停止 nfs 服务：
#/etc/init.d/nfs stop
(2)通过图形界面启动NFS 服务
为了在每次开机时系统都自动启动该服务，可以输入
# serviceconf
打开系统服务

2. 修改/etc/hosts.allow

sshd:ALL

portmap:192.168.10.0/255.255.255.0:allow

portmap:ALL:deny

nfsd:192.168.10.0/255.255.255.0

3. 启动Fedora 9 nfs server

[root@localhost v2.0]# service nfs start.如果在启动之后需要修改exports,可以exportfs -rv重新输出.

4. 可以在本机测试[root@localhost v2.0]# mount -t nfs 192.168.10.6:/pub /var/nfs

5. 在目标板上运行.下面是我第一次在目标板上运行的结果,查询了之后发现是防火墙的问题.

[root@falinux ~]$ mount -t nfs -o nolock 192.168.10.6:/home/leffy/edfa/v2.0 /mnt/win

mount: RPC: Unable to receive; errno = No route to host

mount: nfsmount failed: Bad file descriptor

mount: Mounting 192.168.10.6:/home/leffy/edfa/v2.0 on /mnt/win failed: Bad file descriptor

6. 关闭防火墙[root@localhost v2.0]# service iptables stop[root@localhost v2.0]# service iptables statusiptables: Firewall is not running.

可以看到防火墙已经半闭以上Fedora 9 nfs系统介绍.

eclipse for qt java install

A Download

i、下載JRE(Java Runtime Environment) 。(http://java.sun.com/javase/downloads/index.jsp)

安裝JRE

... /usr/local ]#chmod +x jxx-linux-i586-rpm.bin

... /usr/local ]#./jxxx-linux-i586-rpm.bin

產生/usr/local/jdk1.6.0_25

修改路徑

$gedit /etc/profile

...

export JAVA_HOME=/usr/local/jdk1.6.0_25

export JRE_HOME=/usr/local/jdk1.6.0_25/jre

export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME;lib:$CLASSPATH

export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

...

umask 022

測試是否成功

source /ect/profile

沒任何提示表示成功

ii. (測試Java是否安装成功)
[root@localhost ~]#java –version
http://www.cnblogs.com/images/cnblogs_com/oomusou/JRE3.jpg

iii. download g++

sudo apt-get install build-essential

輸入 gcc，出現“gcc: no input files”，安裝成功！

iv. 下載qt framework

http://qt.nokia.com/downloads

LGPL -> Qt libraries 4.7.3 for Linux/X11(204 MB)

步驟如下連結

http://www.speedfaq.com/jingyan/17375.html

v. 下載 qt and eclipse

http://qt.nokia.com/developer/eclipse-integration

tar vxfz qt-eclipse-integration-linux.x86-1.6.1.tar.gz 後先保留後面步驟使用

linux下eclipse的安装

for c/c++

(下載eclipse-linuxtools-helios-SR2-incubation-linux-gtk)
(解壓後eclipse-SDK-3.2.1-linux-gtk.tar.gz)執行

我是安裝c/c++ eclipse 為了整合qt 之用

安裝步驟如上連結且測試了Hello World 發覺eclipse 真是酷也接下來qt 整在一起吧

install CDT

http://www.eclipse.org/cdt/downloads.php

或者打開eclipse install new software :
選擇或鍵入 http://download.eclipse.org/tools/cdt/releases/helios 此相關pending 後勾選全部下載

接下來qt framework 我解壓縮放在如上 A 第iv 點make 路徑:/usr/local/Trolltech

A v步驟後: 裡面會和 eclipse的資料夾裡features和plugins兩個資料夾，分別將這兩資料夾內的內容放置你Eclipse(以我為例我的Eclipse放置/opt/Eclipse)相對應的資料夾內(Eclipse中也有features和plugins兩個資料夾)，然後啟動 Eclipse，即可。這樣QT就整合完成了。

重起eclipse 後請設好路徑

version name: 4.7.3

Bin path: /usr/local/Trolltech/Qt-4.7.3/bin

Include: /usr/local/Trolltech/Qt-4.7.3/include

**********************************

最後注意開發專案

c\c++ 要include Trollech lib compiler:Gnu\g++

qmake -project

qmake

make

Run

QT console compiler: Gun\ g++
