USE flags for sys-devel/binutils Tools necessary to build programs
||Enable Intel Control-flow Enforcement Technology.|
||Set ld to point to ld.gold instead of ld.bfd|
||Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally|
||Build ld.gold linker|
||Enable the next-generation gprofng profiler|
||Adds support to binutils for cross compiling (does not work with gas)|
||Add Native Language Support (using gettextGNU locale utilities)|
||Build binutils with Profile Guided Optimization (PGO) and LTO|
||Enable plugin support in tools|
||Build static versions of dynamic libraries as well|
||Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)|
||Do not add extra patches which change default behaviour; DO NOT USE THIS ON A GLOBAL SCALE as the severity of the meaning changes drastically|
||Enable support for ZSTD compression|
emerge --ask sys-devel/binutils
Select a newer version
System administrators can use the eselect binutils command to select an alternate version of binutils. This is not normally necessary, since more than one version of the binutils is not installed by default, however it may be necessitated by packages upgrades.
Built-in binutils-config utility
Selecting an alternate version of binutils 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
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 --verbose sys-devel/binutils
