Building OpenOCD for OSX ------------------------ There are a few prerequisites you will need first: - Xcode 4 (install from the AppStore) - Command Line Tools (install from Xcode 4 -> Preferences -> Downloads) - MacPorts (http://www.macports.org/install.php) or - Homebrew (http://mxcl.github.io/homebrew/) libtool, automake, autoconf, pkg-config and libusb can be easily installed via MacPorts: sudo port install libtool automake autoconf pkgconfig libusb [libusb-compat] or with Homebrew: brew install libtool automake libusb [libusb-compat] You should also specify LDFLAGS and CPPFLAGS to allow configure to use MacPorts' libraries, so run configure like this: LDFLAGS=-L/opt/local/lib CPPFLAGS=-I/opt/local/include ./configure [options] If you're using Homebrew, no custom flags are necessary. See README for the generic building instructions. If you use an FTDI-based adapter and have the FTDI kext installed, you will need to unload it prior to using OpenOCD: sudo kextunload FTDIUSBSerialDriver.kext
