Since late last week there have been compile issues for those compiling for the Pixhawk family of boards using ardupilot/master. The error was “error: ‘__builtin_bswap16’ was not declared in this scope” and is discussed in this issue:

Sid’s created a new Pixhawk toolchain installer here: http://firmware.ardupilot.org/Tools/PX4-tools/ (see “pixhawk_toolchain_installer_latest.exe” or here’s the direct link.

The changes vs the previous installer (v14) are:

  1. updated the license file to provide links to (at least some of) the underlying component’s licenses
  2. changed install directory to Pixhawk_Toolchain
  3. updated gcc to 4.9.2

@jane,
It looks like Git is not installed on your machine or perhaps it’s not in your path?

Thank you for your reply, I reinstalled “pixhawk_toolchain” in default path and it worked, but there are also some problems.
