Title

Why do I see a "Failed to generate module" error when generating my Qsys system under Linux?

Description

Due to a problem in the Quartus® II software versions 11.0 SP1 and earlier, you may see the following warning when generating a Qsys system on a Linux machine without the en_US locale installed:

>perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "en_US",
LANG = "C"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C")/
Failed to generate module <module name>

To resolve this issue, as an adminitrator, install the locale with the following command:

sudo locale-gen en_US

This issue is scheduled to be fixed in a future version of the Quartus II software.
