Building OpenOCD for Windows
----------------------------
You can build OpenOCD for Windows natively with either MinGW-w64/MSYS
or Cygwin (plain MinGW might work with --disable-werror but is not
recommended as it doesn't provide enough C99 compatibility).
Alternatively, one can cross-compile it using MinGW-w64 on a *nix
host. See README for the generic instructions.
Native MinGW-w64/MSYS compilation
-----------------------------
As MSYS doesn't come with pkg-config pre-installed, you need to add it
manually. The easiest way to do that is to download pkg-config-lite
from:
http://sourceforge.net/projects/pkgconfiglite/
Then simply unzip the archive to the root directory of your MinGW-w64
installation.
USB adapters
------------
You usually need to have WinUSB.sys (or libusbK.sys) driver installed
for a USB-based adapter. Some vendor software (e.g. for ST-LINKv2)
does it on its own. For the other cases the easiest way to assign
WinUSB to a device is to use the latest Zadig installer:
http://zadig.akeo.ie
For the old drivers that use libusb-0.1 API you might need to link
against libusb-win32 headers and install the corresponding driver with
Zadig.
