介绍如何编译windows版本的openocd。

Environment

本文是介绍在Arch Linux系统上，进行交叉编译，得到最终的exe文件，再在windows下运行openocd的方法。

Host OS: Arch Linux WSL

Compiler: mingw-w64-gcc

Library: libusb-1.0.23, automake, autoconf

Openocd: riscv-openocd

Step by step:

Installation

$ cd ricv-openocd
$ rm jimtcl
$ mv ../jimtcl-51f65c6d38fbf86e1f0b036ad336761fd2ab7fa0 ./jimtcl
$ ./bootstrap nosubmodule
$ LIBUSB1_CFLAGS="-I/mnt/d/software/libusb-1.0.23/include/libusb-1.0" LIBUSB1_LIBS="-L/mnt/d/software/libusb-1.0.23/MinGW32/dll" ./configure --host=i686-w64-mingw32 --enable-ftdi
$ make CFLAGS='-Wno-implicit-fallthrough -Wno-tautological-compare'
$ make install

由于编译器比较新，有些错误，所以改了CFLAG。另外还改了下src/jtag/drivers/libjaylink/config.h

1
#define __USE_MINGW_ANSI_STDIO 1

=>

4
#ifdef __USE_MINGW_ANSI_STDIO
# undef __USE_MINGW_ANSI_STDIO
#endif
#define __USE_MINGW_ANSI_STDIO 1

如果一切顺利，在/usr/local下面生成目标文件。

$ tree .

├── bin
│   └── openocd.exe
├── etc

│   └── man1
│       └── openocd.1

│   │   └── openocd.info-2

│   └── openocd

然后把它打包整个拷贝出来

$ tar czf ~/openocd.tar.gz /usr/local/
$ cp ~/openocd.tar.gz /mnt/d/software/

然后到windows把libusb的dll也拷贝到bin目录下

1
cp /mnt/d/software/libusb-1.0.23/MinGW32/dll/libusb-1.0.dll /mnt/d/software/openocd\usr\local\bin

然后到windows下面执行
