emerge --ask sys-devel/binutils
Select a newer version
Upon binutils package upgrades it is occasionally necessary to select a newer profile to be used for the system's toolchain. This can be done using the binutils-config command. First list known (installed) versions:
 x86_64-pc-linux-gnu-2.25.1 *  x86_64-pc-linux-gnu-2.26.1
Select the newest profile. Either the integer number or the full profile name can be used to select the profile; below the profile name is used:
* Switching to x86_64-pc-linux-gnu-2.26.1 ... [ ok ] * Please remember to run: * # . /etc/profile
Alternatively one can use the eselect binutils command instead of binutils-config.
There are several command-line tools for binary manipulation distributed in binutils, each has its own expectation on acceptable options, arguments, and parameters. Covering them all goes beyond the scope of this article, however they may eventually be expounded upon in the future. See upstream documentation or the appropriate man page for usage on each utility.
When Portage is caught in a
@preserved-rebuild loop and the only culprit failing is binutils, use the following steps to resolve the issue. First use the binutils-config command to select the latest emerged version. See Select a new version section above. After executing this step, return here and perform a
emerge --ask --depclean
Finally perform a
@preserved-rebuild a final time:
emerge --ask @preserved-rebuild
Generally speaking this collection of software tools should only have old versions removed by passing the
--depclean option to emerge.
emerge --ask --depclean sys-devel/binutils
