Understanding make.conf - An Introduction

[Richlion]

Hi All,
I am totally new to Sabayon and Gentoo and this thread is really nice. However, I am trying to find a list of VIDEO_CARDS and INPUT_DEVICES I can remove for sure. There are many Gentoo links for USE, but I could not find any link to see what I have in my /etc/make.conf file to be sure I really can remove things. For example, if I have a VIDEO_CARD:

Code: Select all

00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)


which is related to the i915 supoort, can I change:

Code: Select all

VIDEO_CARDS="apm ark chips cirrus cyrix dummy fbdev fglrx glint i128 i740 i810 imstt mach64 mga neomagic nsc nv nvidia r128 radeon rendition s3 s3virge savage siliconmotion sis sisusb tdfx tga trident tseng v4l vesa vga via vmware voodoo epson"


to this:

Code: Select all

VIDEO_CARDS="i915"


So in the end, are there any VIDEO_CARDS I need to leave, like "vesa vga via"?
If someone could post his example of the sections VIDEO_CARDS and INPUT_DEVICES, it would be of much greate help.

Also, as with the USE parameter, should I get rid of "nvidia" support by specifying "-nvidia", or I can just remove the entry from the VIDEO_CARDS list?

Thanks to everyone,
RIchard.

After changing the /etc/make.conf it is suggested to run some updates:
http://www.gentoo.org/doc/en/handbook/h ... t=2&chap=2

I wouldn't want to recompile my whole system, because I am still not too familiar with Gentoo and Portage. When I run this:
emerge --update --deep --newuse world

I run into problems:

Code: Select all

Calculating world dependencies  .... ........
!!! All ebuilds that could satisfy ">=sys-apps/hal-0.5.10" have been masked.
!!! One of the following masked packages is required to complete your request:
- sys-apps/hal-0.5.10 (masked by: package.mask)
/usr/portage/profiles/package.mask:

# Mask this until we get the input and mounting issues worked out

refer to the Gentoo Handbook.
(dependency required by "app-misc/hal-info-20071011" [ebuild])

!!! Depgraph creation failed.

!!! Problem resolving dependencies for sys-apps/busybox


Maybe it's better to do :
emerge --sync

Thanks for any hints,

not recompiling is kinda pointless than

video should be vesa vga i915
remove any use flags you don't need, no need to - anything, just remove it

Read the error message it's telling why and where

# Mask this until we get the input and mounting issues worked out

/usr/portage/profiles/package.mask

Also, this topic is for make.conf discussion/tips, not portage compiling problems - Make a new topic if u need to

Thanks Wolfden, very easy.

Any suggestions regarding the INPUT_DEVICES ?

Code: Select all

INPUT_DEVICES="evdev keyboard mouse acecad aiptek calcomp citron digitaledge dmc dynapro elo2300 elographics fpit hyperpen jamstudio magellan microtouch mutouch palmax penmount spaceorb summa synaptics tek4957 wacom ur98 vmmouse void wacom"


I only use a keyboard, mouse, my laptop touchpad. Any link with a description about what all these are? If not, I'll do some searches.

Thanks in advance.
Richard

[wolfden]

evdev keyboard mouse synaptics

that is what I would do

Thanks Wolfden, Iv'e been googling & searching Gentoo & other Forums etc to find answers on whats wise to change & whats OK to change & edit in " make.conf " when it comes to a pre built system like Sabayon for a while now & this Tutorial has made things alot clearer & has given those new to Gentoo based desktops answers & confidence in editing make.conf.
The Links are Handy too.
Thanks -LatterDaySaint

Wow! This is very nice!
I wonder how I didn't find this here before (maybe because its an old post).
But it's great!

great informations and links for us begginers!
got me a lot more to read

[valczir]

CFLAGS="-O3 -march=native -funroll-all-loops -m3dnow -msse3 -funit-at-a-time -fpeel-loops -ftracer -funswitch-loops -fomit-frame-pointer -pipe"

No, no, no - you're doing it wrong. You need REAL men's CFLAGS!

Joking aside, don't you think you should be using safer CFLAGS in a newbie guide? Even -march=native should have warnings attached to it, because certain versions of a fair number of packages (including gcc) won't build with -march=native, not to mention the fact that you first have to make sure you're using GCC 4.3.x. With Sabayon 3.5, at least, gcc-config lists GCC 4.2.x as the default version of gcc used.

Just to quote one specific point about the above CFLAGS from the Gentoo Compilation Optimization Guide:

-O3: This is the highest level of optimization possible, and also the riskiest. It will take a longer time to compile your code with this option, and in fact it should not be used system-wide with gcc 4.x. The behavior of gcc has changed significantly since version 3.x. In 3.x, -O3 has been shown to lead to marginally faster execution times over -O2, but this is no longer the case with gcc 4.x. Compiling all your packages with -O3 will result in larger binaries that require more memory, and will significantly increase the odds of compilation failure or unexpected program behavior (including errors). The downsides outweigh the benefits; remember the principle of diminishing returns. Using -O3 is not recommended for gcc 4.x.

[wolfden]

it's just an example make.conf
