Gentoo isn't hard as long as you are up to speed with how to drive it. It's a high performance race engine that you can turn into anything you want it to be, and we are the mechanics. The guys in the pits at races don't consider their engines hard, they just take it in their stride because they have large amounts of clue. Just like most of us here :-) The beauty of Gentoo is that if you do want to make something suitable for Aunt Tillie to use and nothing else out there fits the bill, you can write a wrapper around Gentoo to get what you want, and that's where the complexity lies - in a place Aunt Tillie doesn't need to see it. -- Alan McKinnon alan.mckin...@gmail.com

Ahh there is the bit I was fumbling to remember. package.provided OK, so in this case would I tell portage I am providing the emacs version its pulling in? ie app-editors/emacs-24.4-r1 man portage section on package.provided doesn't make it very clear what should actually go in there. The example for telling portage user will manage 2.6 kernel: sys-kernel/development-sources-2.6.7 But what portage is asking for is app-editors/emacs-24.4-r1 So I'm guessing to tell portage to not worry about that version or any newer one: Something like: =app-editors/emacs-24 If that the proper syntax?

If you're building on the target machine, use the native CFLAG. It

automagically. You don't have to do any more grunt work, figuring out
the flags for your CPU. Computers are supposed to do the hard work. I
use...
FLAGS=-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe
-fno-unwind-tables -fno-asynchronous-unwind-tables

Mind you, if you're cross-compiling on another system, and then moving
the binaries over, you will have to figure out the correct flags. See
below for a method.
Another problem is that there are also cpu-specific USE flags. You
can get a good start on figuring them out, as well as CFLAGS, by running
grep flags /proc/cpuinfo
on the target machine. There will be one line of output for each core.
You'll have multiple identical lines of output.

Well, why not give the standard -O2 -march=native a whirl, perhaps
seasoned with -pipe. Or look at what march=native would actually yield:
Create a simple c file:
cat test.c EOF
int main() { return 0; }
EOF
and look at the output of gcc -v -Q -march=native -O2 test.c -o test
On my Celeron 847 (Sandy Bridge), this yields -march=corei7-avx with a lot
of disabled options which the Celeron doesn't have compared to an actual i7
(had to find this out so I could set up a client config for distcc with an
Haswell i5 as build host).
A minute of searching brought me to¹, so march=native will work.

Files go where Mozilla says they go, the devs can only do so much to make stuff standard. Those are good lists. The only thing I can think to add is that firefox-bin is built with Profile Guided Optimization; the firefox package has the pgo USE flag for that, but it's forced off because it doesn't work and upstream doesn't support it. Building with PGO roughly doubles compile time, as firefox has to be built twice. I don't know what optimization gains there are. As I see it, go with firefox unless you can't spend the cpu cycles to build it locally. That's true of almost all -bin packages +1

On top of that, this laptop has only a year or so left before I replace it, and I know now to avoid Optimus entirely in the future.

As adviced I run emerge --depclean -v -p after a greater update to world. (by the way: Updateing the world is generally to a bad idea...;) Beside other things, gcc-4.7.3 was slated for removal. As gcc-4.8.3 was already installed and gcc-config shows that it is active, I started the above command without -p And it screws up the whole thing badly: There were many, many applications (the shell for example...) which were directly linked to /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.7.3/libgcc_s.so.1 and/or /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.7.3/libstdc++.so.6 After clearing the sdcard and reinstalling the backup I started to emerge all affected ebuilds by hand...only to find, that they were again linked against the old libs. I checked again with gcc-config and found: beagleboneblack:/rootgcc-config -L /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.8.3 beagleboneblack:/rootgcc-config -c armv7a-hardfloat-linux-gnueabi-4.8.3 beagleboneblack:/rootgcc-config -E export PATH=/usr/armv7a-hardfloat-linux-gnueabi/gcc-bin/4.8.3:/lib/rc/bin:/bin:/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/bin/:/opt/bin:/usr/armv7a-hardfloat-linux-gnueabi/gcc-bin/4.8.3:/usr/games/bin:/root/bin export GCC_SPECS= What is going on here? Why still the old compiler and its libraries are used? How can I convince Gentoo to finally switch ti gcc-4.8.3? What do you think? Best regards, Meino Did you run fix_libtool_files.sh? - you have to do it manually after switching gcc to a bew version. BillK Hi Bill, Thanks for your help and hint! :) In the meanwhile I found a trace of a bad install of version 4.8.3: /etc/env.d/*gcc* was not updated. Currently I am reinstalling the whole gcc-4.8.3. - suit and after that I will call fix_libtool_files.sh. Hope it will fix it! Best regards, Meino
