Re: too long to build 2.6.14.2 kernel
[Andreas Orfanos] I hope I post this to the right list. debian-user is probably the right list, actually. The delay was not due to lots of new modules, it was clear that the incremental list of compiled components on the screen was moving up slow. I remember kernel builds where ultra fast, couldn't watch on screen what it was compiled. My guess is that you used a different compiler last time. Specifically, gcc-2.95 is much faster than any newer gcc version, although I understand the 4.x series promises to regain some of that lost efficiency. signature.asc Description: Digital signature

Since the 2.6 branch, the generated output is much less verbose than it was with the 2.4 one. My out-of-topic point: if you want to boost your kernel cooking and you have a couple of boxes around, give a try at `distcc' ;) -- Alexis Sukrieh [EMAIL PROTECTED]
Re: too long to build 2.6.14.2 kernel
Yes! you are right. I try to produce some statistical data with different kernels. The latest 2.4.32 takes an average 6 minutes to build (~500 objects). But 2.6.0 takes more than half an hour for (~3000objects and more). The latest 2.6.14.2 one hour and more, and again we are talking for thousands of object files. I was using a 2GHz Pentium for the builds. Thank for your replies.

My question is: Is it a real problem? How often do you really compile your kernels yourself with all the modules turned on, such as Debian does? I remember kernel builds where ultra fast, couldn't watch on screen what it was compiled. 2.4 used to spit out the entire command line while compiling. Try making with V=1 to get the same effect on 2.6. /* Steinar */ -- Homepage: http://www.sesse.net/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
