Linux support has been removed from the C4 Engine, effective in version 4.2. This decision was made based on the disproportionate cost, both in terms of time and money, that we incur to support Linux relative to a very small return on our investment. This decision was also made to preserve my own sanity since my personal experiences with Linux have been extremely negative and have resulted in huge wastes of time that could have been better spent on more productive tasks. Terathon Software will no longer contribute to the popularity of an operating system that I personally view as inferior in design to both Windows and Mac OS X. Linux has proven to be Frankenstein OS assembled from a disparate array of barely functioning parts with horrible reliability and little potential for future improvement. Time that would have been spent on Linux support will now be used to strengthen our product on platforms with much greater viability.
