# Cross-compile OpenOCD on GNU/Linux for Windows
## Overview
The following was done using OpenOCD 0.8.0 and Archlinux x86_64. Target OS is Windows 7 32bits, but it should also work for 64bits versions.
## Requirements
You need a few packages. Some already exist in community or in AUR so:
yaourt -S mingw-w64-gcc mingw-w64-libusb mingw-w64-hidapi
### LibFTDI
Download this pkgbuild, make your package and install it: mingw-w64-libftdi.tar.gz
makepkg yaourt -U ./mingw-w64-libftdi*.tar.xz
### LibUSB-compat
Download this pkgbuild, make your package and install it: mingw-w64-libusb-compat.tar.gz
makepkg yaourt -U ./mingw-w64-libusb-compat*.tar.xz
#### Fix
Here's the trick, you need to remove the existing usb.h from mingw-w64-headers to be able to install mingw-w64-libusb-compat. There must be a better way to fix this conflict but I didn't have much time to investigate…
## OpenOCD compilation
Get openocd-0.8.0.tar.bz2 from Sourceforge
tar xavf openocd-0.8.0.tar.bz2 cd openocd-0.8.0 # Eventually apply the patches you want autoreconf -fiv mkdir build cd build HIDAPI_LIBS="-lhidapi" ../configure --build=i686-pc-linux-gnu --host=i686-w64-mingw32 --disable-shared make -j8
Get openocd.exe from _build/src/_
It will require the DLL files from _/usr/i686-w64-mingw32/bin/_
## Running OpenOCD
Put the executable and the DLL in the same folder. Install WinUSB drivers for you device (maybe using Zadig). And you should be able to run OpenOCD
