Redhat+Oracle 10g环境搭建完毕后，终端中输入命令 proc
如果有如下错误提示：

[oracle@oracleserver ~]$ proc
proc: error while loading shared libraries: libclntsh.so.10.1: cannot open shared object file: No such file or directory

可以直接在用户配置文件 .bash_profile 中添加:

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

输入以下命令生效：

source .bash_profile

编译.pc程序文件时，如果提示这样的错误：

说明在 pcscfg.cfg 中系统头文件的位置不正确，需要重新设置:
查看pcscfg.cfg文件：

$[oracle@oracleserver ~]$ cat /home/oracle/OraHome1/oracle10g/precomp/admin/pcscfg.cfg
sys_include=(/ade/aime_rdbms_9819/oracle/precomp/public,/usr/include,/usr/lib/gcc-lib/i486-suse-linux/2.95.3/include,/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/include,/usr/lib/gcc-lib/i386-redhat-linux7/2.96/include)
ltype=short

查找头文件 stddef.h 位置：

[root@oracleserver ~]# find / -name "stddef.h" -print
/usr/include/xulrunner-sdk-1.9/system_wrappers/stddef.h
/usr/include/linux/stddef.h
/usr/lib/bcc/include/stddef.h
/usr/lib/gcc/i386-redhat-linux/3.4.6/include/stddef.h
/usr/lib/gcc/i386-redhat-linux/4.1.1/include/stddef.h
/usr/lib/syslinux/com32/include/bitsize/stddef.h
/usr/lib/syslinux/com32/include/stddef.h
/usr/src/kernels/2.6.18-194.el5-i686/include/linux/stddef.h

比较发现，pcscfg.cfg中的/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/include和/usr/lib/gcc-lib/i386-redhat-linux7/2.96/include路径均无效，与实际系统中的路径不符，修改为/usr/lib/gcc/i386-redhat-linux/4.1.1/include和/usr/lib/gcc/i386-redhat-linux/3.4.6/include 即可：

$ cat /home/oracle/OraHome1/oracle10g/precomp/admin/pcscfg.cfg
sys_include=(/ade/aime_rdbms_9819/oracle/precomp/public,/usr/include,/usr/lib/gcc-lib/i486-suse-linux/2.95.3/include,/usr/lib/gcc/i386-redhat-linux/4.1.1/include,/usr/lib/gcc/i386-redhat-linux/3.4.6/include)
ltype=short

写个简单的程序测试下：

$ proc test.pc

最新官方消息，树莓派的摄像头已经可以购买了，可以在 RS Components 或者 Premier Farnell/Element14 上订购。
摄像效果见下图：

以下是官方对于如何装载摄像头做的视频和图文教程，简单翻译了下：

1. 开启摄像头支持
开机后登录，默认用户是 pi，默认密码为 raspberry。在终端输入以下命令升级固件到最新版本：

sudo apt-get update

sudo apt-get upgrade

输入以下命令进入配置管理:

sudo raspi-config

浏览至 camera ，选择 enable

2.如何使用树莓派摄像头软件
raspivid 是一个命令行应用，它可以捕捉视频，而 raspistill 可以帮助你捕捉图片。
-o 或 –output 指定输出文件名， -t 或 –timeout 指定播放预览的时间，以毫秒为单位。要注意的是，默认设置为5秒，且 raspistill 将会捕捉预览期间的最后一帧
-d 或 –demo 会运行demo演示，循环播放各种图像效果。

3.示例命令
以jpeg格式捕捉图像:

raspistill -o image.jpg

以h264格式捕捉5秒视频 format:

raspivid -o video.h264

捕捉10秒视频:

raspivid -o video.h264 -t 10000

在demo模式捕捉10秒视频:

raspivid -o video.h264 -t 10000 -d

查看 raspivid 或者 raspistill 的选项，你可以输入:

raspivid | less
raspistill | less

使用方向键滚动，输入q推出。
