I have a need to run an application that depends on these settings to optimise speed but have found that Ubuntu has no make.conf file which is where I would normally expect to find/tweak these settings. There is no make.conf as each package will define what it needs separately. There are gcc defaults depending on the version, but they aren't accessible to easily change. I don't see why you need to change global settings to affect one application?

I have a need to run an application that depends on these settings to optimise speed but have found that Ubuntu has no make.conf file which is where I would normally expect to find/tweak these settings. CFLAGS is an environment variable that is fed to the [gcc] compiler at build time: http://en.wikipedia.org/wiki/CFLAGS. It isn't really a setting as such. And if you want to change it you will need to recompile whatever the app or library is that needs it to be different. I'm not sure what the Ubuntu packagers use normally, nor if you can read how it was set after a binary has been compiled, but the CFLAGS var *can* be different for each and every package built.

The issue is now sorted as a result of me re-reading the man pages properly this time and noticing that you can set the required flag as an option when you build the run command at the shell. So no need to mess with system wide settings for one application as someone pointed out. Interestingly the 15GiB file was processed seven minutes faster with the flag set than without so at least I know it works :) Lesson learnt: RTFM (thoroughly) Matthew I just got fed up with a desktop taking 14 days to build! I know what you mean. The phrase # emerge -uavDNt world still brings me out in a cold sweat :) I seem to remember a Ubentu or Genbuntu fork being talked about in the past but don't know if it ever got off the ground? Overall though, like you I appreciate the straightforward way that Ubuntu does things on the desktop. I am still in the process of testing it as a platform for my work (digital forensics) but it's looking good so far.
