 |
|
Hi! I was just woundereing what you would recomend me to set in the /etc/make.conf file?
The server is running on a Pentium 166 MHz (not mmx i think.. it did not stand anything about mmx in the /proc/cpuinfo file)
This is what i set the optimization settings to:
| Code: |
# Pentium/Pentium MMX+ exclusive (requires a Pentium Classic or K6 or beyond)
CHOST="i586-pc-linux-gnu"
CFLAGS="-march=i586 -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-march=i586 -O3 -pipe -fomit-frame-pointer"
|
Since this should be a server I have set my USE flags not to use -X -QT -KDE and so on. I havent access to the server as I write this but ill post my USE flags within 10 hours 
Does this sounds OK ? What could i change? Anyone of you installed a server with a P166 and without X? How does it work? What kind of optimazition did you use? What flags did / didnt you use? 
- Thanks!
- Anders |

http://www.freehackers.org/gentoo/gccflags/
might be a good page for you
CHOST="i586-pc-linux-gnu"
CFLAGS="-march=pentium -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-march=pentium -O3 -pipe -fomit-frame-pointer"
seems to be standard and most reasonable setting for p1 without mmx and gcc 3.2.x or greater...
About the use flags...you should be check them twice because you might get surpised if you forget for example -gtk or so 
To be sure, do emerge -p before every emerge until a few merges have passed and you can be sure not to have any X/GUI related things still going on |

This is the USE flags i set for this server:
| Code: |
USE="-oss -3dnow -arts -avi -kde -gnome -opengl -gtk -X -xmms -xm -svga -gpm -qt mysql samba"
|
By the way, is the useflags case sensetive? Does the useflags have any influence on the "emerge system" and "bootstrap" processes?
Does this looks okey? I DONT want X on the server. |

Yes.

Yes, although for bootstrap, the only USE flag that I can think of that would have much effect would be nls when building glibc.

Then always preflight with emerge's "pretend" option, to make sure xfree isn't going to getting dragged in.
