I compile with g++/gcc on ubuntu12.04 and it is "OK" but I cannot cross compile using raspberry pi tools master
我在 ubuntu12.04 上用 g++/gcc 编译，它“OK”，但我不能使用 raspberry pi tools master 进行交叉编译
toolsmaster
CC := /home/Desktop/Simple_Linux_Driver/tools-master/arm-bcm2708/arm-bcm2708-linux-gnueabi/bin/arm-bcm2708-linux-gnueabi-g++
GCC := /home/Desktop/Simple_Linux_Driver/tools-master/arm-bcm2708/arm-bcm2708-linux-gnueabi/bin/arm-bcm2708-linux-gnueabi-gcc
I had install the following item:
我已经安装了以下项目：
-sudo apt-get install libusb-1.0-0-dev
-sudo apt-get install libudev-dev

Its works!!! i need to cross compile and cp .h .so inside raspberry pi cross toolsmaster Below is what i try: Do let me know if i miss out anythings Thanks^^ download libusb latest version tar file.
其作品！！！我需要在 raspberry pi cross toolsmaster 中交叉编译和 cp .h .so 下面是我尝试的：如果我错过了什么，请告诉我谢谢^^ 下载 libusb 最新版本的 tar 文件。
version 1.0.8
版本 1.0.8
$ TOOLCHAIN=/opt/FriendlyArm/toolchain/4.4.3/arm-none-linux-gnueabi
$ PATH=$PATH:$TOOLCHAIN/bin

THE TOOLCHAIN IS SET. for writing programs: add #include to use he library. compile using following:
工具链已设置。用于编写程序：添加 #include 以使用他的库。使用以下编译：
$arm-linux-g++ myprog.cpp -o myapp -lusb-1.0
NOTE: DON'T MISSOUT ON "-lusb-1.0"
注意：不要错过“-lusb-1.0”

If you do above it will install libraries that is for x86. The above libraries should be in raspberry cross-tool chain. if its not present then you need cross-compile it for arm architecture. Then you have to export it by follwing cmd
如果您这样做，它将安装适用于 x86 的库。上述库应该在树莓跨工具链中。如果它不存在，那么你需要为 arm 架构交叉编译它。然后你必须通过以下cmd导出它
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path to library
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path to library
First export the tools using exportcommand.
首先使用export命令导出工具。
export PATH=$PATH:/path to tool chain
export PATH=$PATH:/path to tool chain
Before doing above 1st try the following
在做上述第一次之前尝试以下
e.g export PATH=$PATH:/home/Desktop/Simple_Linux_Driver/tools-master/arm-bcm2708/arm-bcm2708-linux-gnueabi/bin/
例如 export PATH=$PATH:/home/Desktop/Simple_Linux_Driver/tools-master/arm-bcm2708/arm-bcm2708-linux-gnueabi/bin/
if you want to export it everytime in every terminal then .
如果您想每次都在每个终端中导出它，那么 .
vi .bashrc
vi .bashrc
At the end of file just add below command .
在文件末尾添加下面的命令。
export PATH=/path to tool chain bin:$PATH
export PATH=/path to tool chain bin:$PATH
e.g export PATH=/opt/Arm_tool_chain/bin:$PATH
例如 export PATH=/opt/Arm_tool_chain/bin:$PATH
