For a compilation performed in the user interface, the Quartus® II software version 7.0 on Linux and Solaris incorrectly requires two licenses, or seats, of the "quartus" license feature. If your floating license includes a single available license seat, the software generates the following messages during compilation:
Warning: Additional floating licenses for feature quartus not available -- all available floating licenses are in use
Error: Current license file does not support the <device name> device
Error: Quartus II Fitter was unsuccessful. 1 error, 1 warning
This problem is fixed beginning with the Quartus II software version 7.1.
