|
|
Hi all,
I was tying to install ltoize as part of the lto overlay and I ancountered this error where ltoize complains about an outdated version of gcc when on my system I've installed the latest:
Code: | * Warning: Active GCC version '4.2.1' is lower then the expected version '10.2.0', it is recommended that you use the newest GCC if you want LTO.
* Aborting LTOize installation due to older GCC version '4.2.1' -- set I_KNOW_WHAT_I_AM_DOING=y if you want to override this behaviour.
* ERROR: sys-config/ltoize-0.9.10::lto-overlay failed (setup phase):
* (no error message)
*
* Call stack:
* ebuild.sh, line 127: Called pkg_setup
* ltoize-0.9.10.ebuild, line 38: Called die
* The specific snippet of code:
* die
*
* If you need support, post the output of `emerge --info '=sys-config/ltoize-0.9.10::lto-overlay'`,
* the complete build log and the output of `emerge -pqv '=sys-config/ltoize-0.9.10::lto-overlay'`.
* The complete build log is located at '/var/tmp/portage/sys-config/ltoize-0.9.10/temp/build.log'.
* The ebuild environment file is located at '/var/tmp/portage/sys-config/ltoize-0.9.10/temp/die.env'.
* Working directory: '/var/tmp/portage/sys-config/ltoize-0.9.10/empty'
* S: '/var/tmp/portage/sys-config/ltoize-0.9.10/work/ltoize-0.9.10' |
This is the output of merege --info:

I'm using clang on my system so I tried to fall back ltoize adding it in the /etc/portage/package.env and make it use the default environment but nothing seem to change.
Furthermore running emerge --update --deep @world displays another error from sys-apps/man:

You have a bunch of overlays here that are producing errors - you should contact the overlay maintainer for issues, or remove the overlays and see if the problem still exists... _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD

Yntil you get your system stabilized do not use clang.
Also try another version of ltoize
This works just fine
Code: |
sys-config/ltoize-0.9.10::lto-overlay
|
Also you man package originates in mv overlay.
It SHOULDNT
Generally mv will pull many bloatware bs.
Plz create two files
Code: |
/etc/portage/package.mask/MV
/etc/portage/package.unmask/MV
|
The first
And the second
Code: |
app-portage/portage-bashrc-mv::mv
app-shells/runtitle::mv
|
These are the only two packages you need from mv for lto.
All the rest is uneeded.
Also it helps if your system is ~arch for lto. _________________
