Description Richard Li 2019-12-11 15:48:37 UTC
dev-util/valgrind says:
Valgrind will not work if glibc does not have debug symbols.
To fix this you can add splitdebug to FEATURES in make.conf.
and remerge glibc.

However, I get "internal file collisions" when I actually add FEATURES="splitdebug".

 * Package 'sys-libs/glibc-2.29-r7' has internal collisions between non-
 * identical files (located in separate directories in the installation
 * image (${D}) corresponding to merged directories in the target
 * filesystem (${ROOT})):
 * 
 *      /usr/lib/debug/usr/lib64/Mcrt1.o.debug
 *              /usr/lib/debug/usr/lib/Mcrt1.o.debug
 *              /usr/lib/debug/usr/lib64/Mcrt1.o.debug
 *                      Differences: size, content
 * 
 *      /usr/lib/debug/usr/lib64/Scrt1.o.debug
 *              /usr/lib/debug/usr/lib/Scrt1.o.debug
 *              /usr/lib/debug/usr/lib64/Scrt1.o.debug
 *                      Differences: size, content
 * 
 *      /usr/lib/debug/usr/lib64/audit/sotruss-lib.so.debug
 *              /usr/lib/debug/usr/lib/audit/sotruss-lib.so.debug
 *              /usr/lib/debug/usr/lib64/audit/sotruss-lib.so.debug
 *                      Differences: size, content
 * 


I guess this more likely is a portage issue rather than a glibc one, but not completely sure.

Your profile is default/linux/amd64/17.1/desktop/plasma/systemd.

Do you have /usr/lib and /usr/lib64 being different directories?

Please post your output of:
$ ls -ld /usr/lib* /lib*

I do not know if making /usr/lib/debug/usr/lib a symlink to lib64 (/usr/lib/debug/usr/lib64) was standard practice in 17.0 profiles.
In 17.1 profiles, these directories (/usr/lib/debug/usr/lib and /usr/lib/debug/usr/lib64) should certainly be separate.

You can do the following:
1. Delete /usr/lib/debug/lib symlink (if it exists as symlink).
2. Delete /usr/lib/debug/usr/lib symlink.
3. Rebuild all packages which are registered as installing /usr/lib/debug/lib or /usr/lib/debug/usr/lib. Find them using:
   $ cd /var/db/pkg
   $ grep -l /usr/lib/debug/lib/ */*/CONTENTS
   $ grep -l /usr/lib/debug/usr/lib/ */*/CONTENTS

Actually it could result in orphaned files (located in /usr/lib/debug/{,usr/}lib64 but previously registered in /usr/lib/debug/{,usr/}lib), so better to delete whole /usr/lib/debug:
1. Delete /usr/lib/debug
2. Rebuild all packages registered as installing /usr/lib/debug:
   $ cd /var/db/pkg
   $ grep -l /usr/lib/debug/ */*/CONTENTS

Simpler command:
emerge -1 /usr/lib/debug

Maintainer of app-portage/unsymlink-lib can decide if app-portage/unsymlink-lib should handle /usr/lib/debug/{,usr/}lib* or not.

Please file a separate bug. I'd like to focus on restoring user's system in this bug.
