CentOS安装OpenOCD

1. 下载openocd
   http://openocd.org/

2.解压
unzip openocd-0.10.0.zip

3. 配置
   ./configure --enable-ftdi --enable-openjtag
   报错，提示需要安装libftdi

4. 安装libftdi
   略

5. 继续配置
   ./configure --enable-ftdi --enable-openjtag
   报错，提示找不到libusb-1
   configure: WARNING: libusb-1.x not found, trying legacy libusb-0.1 as a fallback; consider installing libusb-1.x instead
   configure: error: libusb-1.x is required for the MPSSE mode of FTDI based devices

安装libftdi的时候已经安装过libusb-1.0了，应该是路径问题
我的libusb-1.0安装在/usr/local/lib下
控制台执行如下命令
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:$PKG_CONFIG_PATH
再次执行./configure --enable-ftdi --enable-openjtag，通过

6. 编译安装
   make
   make install
