[gentoo-user] Identical machines - dissimilar results - trying to fix

[gentoo-user] Identical machines - dissimilar results - trying to fix

[Mark Knecht]

Hi,
   I have two 15-month old Pundit-R machines that I've been updating.
One machine (myth12) I rebuilt from scratch. It works. On the second
machine (myth14) I went the update path since it also servers as a NFS
server and was hard to take off-line. It is not working. The
overriding problem right now is that the ati-driver does not load
correctly on Myth14. ati-drivers is required as I use the TV output,
not the VGA to drive the TV inputs.

   I've been going through the machines with a fine tooth comb looking
for differences and they are now very close except for a couple of
things that I would very much like to get some info on. Thanks in
advance

1) Myth12, which works, only uses gcc-3.4.6-r1. Myth14, which was
updated, has both gcc-3.4.6-r1 as well as gcc-3.3.6.

2) Myth12, which works, has libstdc++ installed while Myth14 does not.

myth12 ~ # eix -I libstdc
* sys-libs/libstdc++-v3
     Available versions:  ~3.3.3-r1 3.3.4 ~3.3.6
     Installed:           3.3.4
     Homepage:            http://gcc.gnu.org/libstdc++/
     Description:         Compatibility package for running binaries
linked against a pre gcc 3.4 libstdc++

myth14 ~ # eix -I libstdc

Found 0 matches
myth14 ~ #

3) Myth14 seems to use the older compiler:

myth14 ~ # gcc-config -l
 [1] i686-pc-linux-gnu-3.3.6 *
 [2] i686-pc-linux-gnu-3.3.6-hardened
 [3] i686-pc-linux-gnu-3.3.6-hardenednopie
 [4] i686-pc-linux-gnu-3.3.6-hardenednopiessp

 [8] i686-pc-linux-gnu-3.4.6-hardenednopie
 [9] i686-pc-linux-gnu-3.4.6-hardenednopiessp

myth14 ~ #

myth12 ~ # gcc-config -l

 [2] i686-pc-linux-gnu-3.4.6-hardened
 [3] i686-pc-linux-gnu-3.4.6-hardenednopie
 [4] i686-pc-linux-gnu-3.4.6-hardenednopiessp
 [5] i686-pc-linux-gnu-3.4.6-hardenednossp
myth12 ~ #

4) If I diff all the packages that would be installed by emerge -DuN
--emptytree world on both machines I see some differences with '%' in
the way the results are reported. What would cause this?

myth14 ~ # diff myth12-test-build-list myth14-test-build-list

QUESTION: How would I make Myth14 work like Myth12?

1) Can I safely emerge libstdc++ on Myth14, use gcc-config to twitch
to the new compiler, and then emerge -C gcc-3.3.4? Will Myth14 still
function?

2) What is causing the differences in the output of emerge with the
'%' on someuse flags? How can I make those identical?

What else might I need to do?

Thanks,
Mark

In reverse order...

The % means it's a new use flag added to the ebuild. It did not exist when
the package was originally emerged.

dDo not remove the old gcc (3.3.4) until you've got everything rebuilt with
3.4.6.

Here's everything you need to know on upgrading the compiler version:

Thanks Devon. The link is very helpful.

Cheers,
