gentoo gcc compile error Windsor Locks, Connecticut

The various qt-* packages are a nice example on this matter. What's behind the word "size issues"? Using revdep-rebuild causes only packages which actually link against GCC libraries to be rebuilt, while the #first-install-emerge-e causes your entire new install to be recompiled with the new GCC version and Slots in Gentoo Gentoo allows installing multiple versions of packages side-by-side in different “slots.” This avoids dependency problems.

ImportantIf you're upgrading on a SPARC machine, you will have to take the way of the complete system rebuild due to some internal ABI changes in GCC's parameter passing. For example, the library names used for revdep-rebuild below are GCC 3.3 specific, as well as the need to install libstdc++-v3 . root #revdep-rebuild --library libstdc\+\ -- -p -v root #revdep-rebuild --library libstdc\+\ NoteIt is possible that you might have problems with non-existing package versions due to them being outdated or masked.

So resintallation of glibc fixed it for me. Run the command from update 4 with -v, so it tells you exactly what it is trying to do, and hunt down the programs it is trying to run. UPDATE 3 I have tried to reinstall gcc-4.6.3 from binary package via emerge -avK gcc:4.6 It completed successfully but error didn't go. i686-pc-linux-gnu-gcc checking whether the C compiler works...

For backwards compatibility the SONAME of was not bumped, instead, inline namespaces in combination with ABI tags are used now. Regardless, I’m going to try this guide on recompiling each package only once and see how it goes. The time now is 10:36 PM. Gentoo is a trademark of the Gentoo Foundation, Inc.

Frequent Error Messages If your system complains about something like libtool: link: `/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/' is not a valid libtool archive , please run /usr/share/gcc-data/$CHOST// 3.3.6 (substitute "3.3.6" with the version numbers from with a path to the gcc versions bin directory. Most of this FUD comes from the confusion surrounding ABI incompatibility. Baron Schwartz's Blog How to update a GCC profile on Gentoo Wed, Jun 7, 2006 in Programming Multiple versions of GCC can be installed side-by-side in a Gentoo GNU/Linux system.

You can browse the url to Create that directory. For example, it’s possible to run programs that require different versions of libraries, because they can all coexist happily (the lack of this feature on Microsoft Windows is known as DLL However, there is one exception -- upgrades to bug fix releases, like from 3.3.5 to 3.3.6 in case you don't use the "multislot" feature allowing them to coexist on one system. Downgrading GCC might have unwanted side effects.

This guide will document the necessary steps required to perform a seamless upgrade of the compiler used by your Gentoo box. The revdep-rebuild method is faster and requires use of the revdep-rebuild tool from package gentoolkit while the other option rebuilds the entire system from scratch so it will make use of A specific section is dedicated to the #Upgrading_from_GCC-3.3_to_3.4 and issues with libstdc++ . Using revdep-rebuild This method requires that you first install gentoolkit if you have not already done so.

So you just saved me from possibly severyle breaking my install, thanks! does when used this way, it's an alias to source, so if you really wanted to, you could just source /etc/profile. The time now is 03:36 AM. I've noticed that you run with ACCEPT_KEYWORDS="amd64 ~amd64", which can cause unexpected problems beyond unstable packages.

Which packages are known to need a rebuild? However, some GCC upgrades break binary compatibility; in such cases a rebuild of the affected packages (or even whole toolchain and system) might be required. Running through all steps above is time consuming, but solves most emerge compilation errors (if the package itself isn't broken ofcourse). I was just about to go back and fix that, and then I saw you had replied.

ImportantIn case you're upgrading from GCC-3.3, you should runemerge --oneshot sys-libs/libstdc++-v3 to provide compatibility with older binary C++ applications. If you want to read the lengthy reasoning behind GCC upgrades, please continue with GCC Upgrading Explained. GCC only makes C++11 ABI stability guarantees beginning with version 5.1. This may take some time, so have some patience.

Chebyshev Rotation What Accelerates a Vehicle With a CVT? How to select a profile On my workstation at work, I became root, then ran the following command to view available profiles: # gcc-config -l [1] i686-pc-linux-gnu-3.3.6 * [2] i686-pc-linux-gnu-3.3.6-hardened [3] If you'd like to contribute content, let us know. The following table gives the packages that, if installed, need to be rebuilt and why.

If this is the case, you will want to use the --package-names option to revdep-rebuild . I'd start by changing those to something more conventional, like CFLAGS="-march=core2 -O2 -pipe" and try this compile again. – Jun 14 '12 at 19:27 Thx for your reply :-)
