Please provide emerge --info. Also, what are the exact CFLAGS you used for this package?

Please upgrade to >=dev-util/debugedit-5.1 or remove the "-gz" option from CFLAGS.

dev-util/debugedit-5.0-r3 works for me with CFLAGS="-O2 -g". Perhaps one of your other flags triggers the issue as well.

OK. ---- A different issue, which seems specific just to app-arch/gzip, is that gdb cannot find the debug file: $ gdb /bin/gzip-reference Reading symbols from /bin/gzip-reference... (No debugging symbols found in /bin/gzip-reference) $ gdb /usr/bin/gzip-reference Reading symbols from /usr/bin/gzip-reference... (No debugging symbols found in /usr/bin/gzip-reference) $ readelf --string-dump=.gnu_debuglink /bin/gzip-reference String dump of section '.gnu_debuglink': [ 0] gzip-reference.debug [ 19] Y�' gdb is trying to open "/usr/lib/debug//usr/bin/gzip-reference.debug", but the package installed "/usr/lib/debug/bin/gzip-reference.debug".
That's bug 917287.
(I don't think there's a need to use -gz with compressdebug anyway, is there?)
(In reply to Sam James from comment #11) > (I don't think there's a need to use -gz with compressdebug anyway, is > there?) I think the interaction of the various debug/compress flags during build and install is too complicated, which results in too many unexpected outcomes. compressdebug doesn't compress files in /var/tmp/portage if FEATURES=noclean is being used, thus the need for -gz and -Wl,--compress-debug-sections. ---- If move the two CFLAGS/LDFLAGS options from make.conf to /etc/portage/env/noclean, and add compressdebug+splitdebug to FEATURES in make.conf, I will have to live with splitdebug bugs. ---- I have -g1 in CFLAGS by default and thus want to compress debug sections by default.
