The primary goal of the Distribution Kernel project is provide a seamless kernel upgrade experience to Gentoo users. Refer to the troubleshooting section for some commonly reported issues. The euse -a command reads the current active USE flags and displays them. Select a number and the file will be displayed using the paging program specified in the PAGER environment variable. Ebuilds may have a Gentoo revision number associated with them. To fulfill its function properly, the libtool script uses various library locations that have hard-coded gcc version information in them. In such cases, first update your x11-libs/wxGTK. The euse -a -l command does the same for active local USE flags. If you are upgrading to GCC 4.1, or GCC 5.1, you would probably encounter ABI issues. Users should run eclean-dist to clean source files from DISTDIR. Then when you go back and do world, that should rebuild everything with the new toolchain. ansible-gentoo-laptop. (This bug, now obsolete, was fixed in bug #676878 in 2019.). Run your own commands to fill default image with some preinstalled utitilies. The primary goal of the Distribution Kernel project is provide a seamless kernel upgrade experience to Gentoo users. If your x11-libs/wxGTK versions are < 3.0.4-r2 (slot 3.0) or < 3.0.4-r302 (slot 3.0-gtk3), this applies to you. To prevent this, the revdep-rebuild command should be run against the libstdc++.so.5 library when moving from GCC 3 to GCC 4.1, or libstdc++.so.6 when moving from GCC 4 to GCC 5.1. I made sure /etc/portage/make.conf was configured so that ~amd64 packages would be installed, and then: # emerge gcc -u # gcc-config x86_64-pc-linux-gnu-6.3.0 # . If you edit the wiki article, please do, https://wiki.gentoo.org/index.php?title=Gentoolkit&oldid=812255. For gentoo to work correctly under the hypervisor some feature flags have to be disabled. Test 2: Rebuild @world. depends on exact gcc version, may encounter linking errors with other ebuilds making use of LLVM (e.g. Apart from such "benign" benefits, rebuilding everything from scratch may be necessary in some cases to fix problems that don't seem to have any obvious cause. Most GCC upgrades are as simple as switching the compiler version (here from 5.4.0 to 6.4.0) and rebuilding sys-devel/libtool: Check the current version number and then uninstall the old version: GCC upgrading has always been mystified, with suggestions ranging from "users do not need to do anything" to "users will need to rebuild the entire system twice". See below.) Step 3: Moving to the new kernel's folder. For more information on eclean and tips on maintaining a cruft-free system, please read man eclean or check the eclean article. For more information on USE flags, please refer to the USE Flags. Anytime your baby wheels get fucked up and go missing a little bit o' theyselves, just cruise or sputter on in to Alpine to be DISMANTLED! For more information and some examples, see: The following table gives the packages that, if installed, need to be rebuilt and why. Which packages are known to need a rebuild? -g and -l are sub-options to euse and need an option before them (like -a) to function correctly. Hours of operation: 9 am - 5 pm Monday-Friday . /etc/profile # emerge world -eav --keep-going Gentoolkit is a suite of tools to ease the administration of a Gentoo system. An ABI (Application Binary Interface), is a set of conventions used by all tools that deal with binary representation of programs, including compilers, assemblers, linkers, and language runtime support (source: GCC Binary Compatibility). --nospinner Disables the spinner for the session. eread is a simple utility to display elog files produced by Portage since version 2.1. Kernel upgrade in Gentoo involves these steps: Step 1: Emerging the new kernel sources. The commands used for this are euse -E flagname (enable a flag) and euse -D flagname (disable a flag). He tirelessly managed Gentoo’s Perl support, and was active in the Rust project as well as in many other corners. The /etc/portage/make.conf file looks like so after the command was ran: Again, the /etc/portage/make.conf file after the command: This tool is Gentoo's Reverse Dependency rebuilder. The saving of elog files can be enabled by setting a couple of variables in /etc/portage/make.conf: Once elog has been set up to satisfaction, run eread to view the log files. The C++ ABI is forward-compatible, but it ensures only that higher (or same) GCC versions can be used when building applications and linking libraries (compared to the GCC version used to build those libraries). euse is able to set or unset USE flags. (And if you have dev-python/wxpython, update it too. The "safest" but slowest way to accomplish this is to use the --emptytree (-e) option of emerge to rebuild the system set and then the world set : root # emerge --ask --emptytree --usepkg=n @system root # emerge --ask --emptytree --usepkg=n @world Try this approach before reporting bugs that might have been caused by a GCC upgrade. After that, we can go on and try # and update. The "safest" but slowest way to accomplish this is to use the --emptytree (-e) option of emerge to rebuild the system set and then the world set: Try this approach before reporting bugs that might have been caused by a GCC upgrade. These archived packages are kept in PKGDIR, usually /var/cache/binpkgs. revdep-rebuild --ignore --pretend revdep-rebuild.sh --ignore --pretend If previous commands result in package rebuild then review again logs and possible configuration changes elogv etc-update Verify / validate dependency starting from "world" fileset emerge --pretend --verbose --update --deep --newuse --with-bdeps=y @world If dev-libs/boost needs to be rebuilt, one will get the following error message: During updates, you might encounter an error like the following: This means that you are trying to build a package with an older GCC version than that with which some depending libraries were built.
