It's platform-specific--it doesn't occur on redhat-based systems--so the right thing to do is to check for it and only add it if needed. SCons has hooks/primitives for that sort of thing. I'd prefer to do things the right way. A half-way patch would be to detect Ubuntu/Debian and then blindly hack it (http://xmodulo.com/2012/05/how-to-check-linux-version.html ). I'd rather not enable it for all platforms. -Daniel ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the QSERV-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=QSERV-L&A=1
