[gentoo-user] mesa-10.3.7-r1 S3TC option

2015-02-20 Thread Mick
After I updated mesa to 10.3.7-r1, I was provided with this message:

 Messages generated by process 2287 on 2015-02-19 20:32:50 GMT for package 
media-libs/mesa-10.3.7-r1:

LOG: postinst
Note that in order to have full S3TC support, it is necessary to install
media-libs/libtxc_dxtn as well. This may be necessary to get nice
textures in some apps, and some others even require this to run.


I couldn't see a USE flag, which is what I was expecting for enabling S3TC 
support and pulling in media-libs/libtxc_dxtn as a dependency.  So I emerged 
media-libs/libtxc_dxtn manually.  Is this how it is meant to be, or is there a 
USE flag missing from mesa?

Looks like you are using pump mode. Disable it and use normal
distcc.

 These are repeatable errors and they occur on all three of my mythtv
 frontends.
 
 Now, I've disabled distcc on one machine completely and above packages
 compile fine, so it must be something to do with distcc. So that's what
 I'm doing for the time being.
 
 However, this poses another question: is there a way to tell portage to
 NOT use distcc for certain packages? Rather than manually disabling it.

Yes, there is. Create a file /etc/portage/env/no-distcc.conf with
the following content:

FEATURES=${FEATURES} -distcc

and add the following entry in /etc/portage/package.env (create
file, if it doesn't exist):

category1/foo no-distcc.conf
category2/bar no-distcc.conf

Yes, I read about how it works and enabled it. Of course I didn't think
of that when these errors happened. I'll try disabling that shortly.

Good to know, thanks. Hopefully I won't need it after disabling distcc-pump.

Re: [gentoo-user] compiling via distcc

 People do it all the time. You have to set up the amd64's to cross compile.
 
 https://wiki.gentoo.org/wiki/Distcc/Cross-Compiling

One doesn't need to setup cross-compilation in order to generate
x86 code on amd64 systems: 64-bit amd64 gcc natively supports this,
just be sure to add -m32 to your {C,CXX,F,FC,LD}FLAGS variables.

Care should be taken with -march=native or -mtune=native arguments.
Vanilla distcc doesn't support this. Patch can be taken here[1] or
distcc from my overlay[2] may be used.

Another approach will be to use one powerful box to build all
packages for an older system: either root filesystem may be
exported via NFS to a powerful host or just copy entire disk image
to and fro that host; afterwards just setarch  chroot to that
image / NFS mount and build all packages using modern hardware.
An old but still useful guide is here[3].

Yes, I'd forgot to adjust for my moving the portage tree to a more

  That shows every ebuild, you may want to reduce it to a list of
  packages
 
  for i in $(grep -Erl 'inherit.*systemd' /var/portage)
  do
  dirname $i
  done | sort -u
 
 
 Yea, sure, cool.  (THANKS). However, I was looking for (wink wink nudge
 nudge) something sexy, using VDB (/var/db/pkg/)

That only shows installed packages. If you want something a little more
portagey, you could use qgrep.
