2009

Using 10.0 profile and x11-libs/libxcb upgrade

Be sure to run revdep-rebuild afterwards, in my case a total of 66 packaged needed a rebuild.

# revdep-rebuild

Portage preserve-libs feature and e2fsprogs/util-linux upgrade

Portage keeps complaining about preserved libs, even after multiple runs of emerge @preserved-rebuild.

# emerge @preserved-rebuild

# rm /lib/libuuid*

# rm /lib/libblkid*

# emerge util-linux --oneshot

Warning notice about broken symlinks during upgrade of app-misc/ca-certificates

Code: Error message

* Broken symlink for a certificate at /etc/ssl/certs/class3.pem * Broken symlink for a certificate at /etc/ssl/certs/root.pem * Broken symlink for a certificate at /etc/ssl/certs/UTN_USERFirst_Object_Root_CA.pem * Broken symlink for a certificate at /etc/ssl/certs/QuoVadis_Root_Certification_Authority.pem * You MUST remove the above broken symlinks * Otherwise any SSL validation that use the directory may fail! * To batch-remove them, run: * find -L /etc/ssl/certs/ -type l -exec rm {} +

Do as you've been told and run:

# find -L /etc/ssl/certs/ -type l -exec rm {} +

bash error message

Code: Error message

>>> No outdated packages were found on your system. * Regenerating GNU info directory index... * Processed 87 info files; 1 errors. install-info: No such file or directory for /usr/share/info/bashref.info.gz

bashref.info.gz was replaced by a tar.bz2 version bashref.info.bz2, thus you can safely delete the older symlink.

# rm /usr/share/info/bashref.info.gz

Emerge: error: C compiler cannot create executables

e.g. while emerging sys-apps/sandbox

Code: Error message

checking for i686-pc-linux-gnu-gcc... i686-pc-linux-gnu-gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details.

This problem arises if you've once had eselect-compiler installed on your system. It was buggy and has been deprecated for now (use gcc-config). You can solve this issue by manually removing all left over files created by eselect-compiler. To identify all of them:

# find /usr/bin | xargs strings -f 2> /dev/null | grep "Unable to determine executable" | cut -d : -f 1

Code: Example Output

You need to enable following kernel option.

Linux Kernel Configuration: Kernel .config

KDE: When inserting a CD nothing happens

If you still own a ATA/IDE CD/DVD-ROM drive you need to enable the "legacy /proc/ide/ support" kernel option.
