1、安装交叉编译工具链:

    sudo tar jxvf arm-anykav500-linux-uclibcgnueabi_V1.0.03.tar.bz2 -C /opt/

安凯文档描述解压,没有带-C /opt,需要注意下

正确方式:

2、修改/etc/profile文件

加入:export PATH=$PATH:/opt/arm-anykav500-linux-uclibcgnueabi/usr/bin/

保存后执行:

source /etc/profile

 

3、检测是否安装成功:

arm-anykav500-linux-uclibcgnueabi-gcc -v

 

4、在编译platform程序时候出错

jacklong@jacklong-VirtualBox:~/anyka/V1.01/PDK/SDK/sdk_release_dir/platform$ make all

jacklong@jacklong-VirtualBox:~/anyka/V1.01/PDK/SDK/sdk_release_dir/platform$

网上搜索了,和我电脑环境一样

只有libmpfr.so.6 ,没有libmpfr.so.4

解决:

链接一下:

sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4

编译成功

 

5、如果是32为的环境,编译会提示:

这样只能安装64位环境了
