前言 之前使用openocd软件连同busblaster B3C硬件对hg255d路由器进行JTAG调试时，一直只能下载网络上编译好的openocd windows版软件，如果自己需要对openocd进一步了解和学习，不可避免需要从源码进行编译。编译linux版的openocd一般比较顺利，在ubuntu系统下，一般通过apt命令安装必要的依赖库就可以了。但是编译window版的openocd则比较麻烦，一般有两个方向，一个是在windows系统下编译，通过cygwin或者msys，mingw等软件环境，安装libusb等库，另一个方向是在linux下通过mingw进行交叉编译。第一个方向尝试了下，一直不成功，后来就根据网络上有个成功的范例，改为在linux下进行交叉编译了。
linux系统的选择 【openocd|openocd 0.6.0/0.10.0（ windows版） 在debian6/debian10系统上的交叉编译】以前用linux都是用ubuntu的，方便联网下载安装软件。刚开始在ubuntu上尝试编译，一直失败。后来看到这个项目https://github.com/caspencer/openocd-mingw32-build-scripts。这上面说在debian下编译成功了。于是也下载了debian进行编译。
mingw工具的选择 debian系统最新的稳定版本为10，在debian10下一开始并没有成功，因为无法按照那个项目中介绍的安装gcc-mingw32软件，也就是没有安装脚本中使用的i586-mingw32msvc工具。在debian10中只能安装i686-w64-mingw32工具。后来查了下，i686-w64-mingw32替代了i586-mingw32msvc。通过尝试发现，在debian6.0.10中才能安装i586-mingw32msvc。
debian 6.0.10下的编译 于是在debian 6.0.10系统下对项目https://github.com/caspencer/openocd-mingw32-build-scripts中的脚本进行编译，发现这个脚本都是临时在线下载libusb,libftdi和openocd的源码再进行编译，而在下载libusb代码时失败了，所以干脆手动到各个网址下载软件包，libusb-win32-src-1.2.5.0.zip，libftdi-0.19.tar.gz，openocd-0.6.0.tar.gz（这里openocd脚本中没有明确说版本，刚开始用最新版0.10.0编译失败，后来在build.sh文件中看到“OUTPUT_ZIP= C W D / o p e n o c d ? 0.6.0 ? d e v ? m i n g w 32 ? CWD/openocd-0.6.0-dev-mingw32- CWD/openocd?0.6.0?dev?mingw32?OUTPUT_ZIP_DATE.zip”这么一行，于是猜测作者用的openocd是0.6.0版本），修改脚本中关于在线下载软件的代码，改为直接使用压缩包。成功编译出windows版的openocd。

debian 10.0.0 下的编译 因为openocd0.6.0已经很旧了，如何编译openocd0.10.0呢，并且使用i686-w64-mingw32编译是不是可以呢。发现是可以的。在debian10中编译openocd参考了https://blog.csdn.net/lshjn/article/details/82528076 一文。
首先安装一些依赖包
sudo apt-get install build-essentialcmake automake zip libtool
sudo apt-getinstalli686-w64-mingw32-gcc
sudo apt-getinstalli686-w64-mingw32-g++
sudo apt-get install libboost-all-dev
sudo apt-get install libtool
sudo apt-get install libudev-dev
sudo apt-get install flex
Sudo apt-get install cmake
然后交叉编译libusb，libconfuse,libftdi,openocd。
