What should I do after upgrading GCC Gentoo?
If such a problem has arisen following a GCC upgrade and persists after using the revdep-rebuild approach described above (and after rebuilding any other obviously relevant packages), a complete system rebuild may be the answer.
How can I get my Gentoo to chroot?
Emerge will just work. Build something small as a test then check that the package has appeared in /var/cache/binpkgs emerge whatever is needed. /home/rescue will stay around until deleted and it is only a chroot away. Upon return, don’t forget to redo the bind mounts.
How to fix my Gentoo-gentoos Wiki Wiki?
If the package needed is part of the stage3, use the quickpkg tool to make a binary package. Take care with quickpkg, it either drops configuration files or copies them in their current state from the install. This may be undesirable. Building pristine packages is safer and there may be the gcc C++ ABI Version issue to avoid too.
Can you add buildpkg to my Gentoo features?
Nervous users can add the -v option to tar. Once the damage is fixed, delete /home/rescue, or keep it around for next time. with adequate space, it may be desirable to add buildpkg to your FEATURES as a regular thing.
Do you always get the same GCC version?
Such packages are usually bumped by package maintainers simultaneously, so they will always be built with the same GCC version. Cherry-picking re-installs on these packages might prove to be troublesome. Some people swear that they need to rebuild every single package on their system when a new GCC version is made available.
Why does it take so long to upgrade GCC?
Enjoy the new compiler! 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”. The uncertainty was caused by confusion about ABI incompatibility, something that nowadays rarely causes problems.
Do you need to rebuild wxPython after upgrading GCC?
Rebuild both of wxGTK and wxpython, if you have both. If you rebuild only one of the two after a GCC upgrade, it will break things. See bug #639276. Be sure to rebuild the correct slot (s) of wxGTK! Some collections of packages need to be built with the same compiler (for example, the various qt-* packages).
Which is the latest version of GCC for FreeBSD?
At the moment of this writing, the latest release of gcc is version 4.9.0. And I use FreeBSD 10.0. I actually need g++, the C++ compiler; but I need to install something like gcc49 package for it, right?
Can you upgrade GCC from 4.1 to 5.1?
If you are upgrading to GCC 4.1, or GCC 5.1, you would probably encounter ABI issues. 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.
Do you need GCC to install G + +?
But you don’t really need GCC for the ports, all ports that already depend on GCC will use GCC. And yeah g++ will be installed with all GCC ports. Thanks for contributing an answer to Unix & Linux Stack Exchange!
