razer-bw-te-ctl
|
||||||
|
|
||||||
|
This program makes it possible to change the configuration of your Razer
|
||||||
|
BlackWidow Tournament Edition keybooard from within Linux, *BSD or any other
|
||||||
|
POSIX-compatible system supported by libusb.
|
||||||
|
|
||||||
|
Make sure to let the Windows Razer Synapse tool upgrade the firmware to the
|
||||||
|
newest version before running the program. There might be some issues otherwise
|
||||||
|
due to protocol changes, although I don't really deem it very probable.
|
||||||
|
|
||||||
|
Run `razer-bw-te-ctl --help' or `man razer-bw-te-ctl' for usage information.
|
||||||
|
|
||||||
|
Installation
|
||||||
|
============
|
||||||
|
Build dependencies: cmake >= 2.8.5, help2man, libusb >= 1.0
|
||||||
|
|
||||||
|
$ git clone git://github.com/pjanouch/razer-bw-te-ctl.git
|
||||||
|
$ cd razer-bw-te-ctl
|
||||||
|
$ mkdir build
|
||||||
|
$ cd build
|
||||||
|
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr
|
||||||
|
# make install
|
||||||
|
|
||||||
|
Note that there's no "make uninstall".
|
||||||
|
|
||||||
|
For Debian-based distros, you can do the following instead of the last step:
|
||||||
|
$ cpack -G DEB
|
||||||
|
# dpkg -i razer-bw-te-ctl-*.deb
