I'm trying to debug inspect googleearth (a 32-bit application) using gdb
on an x86_64 system. Gdb starts OK, but when I attempt to run
googleearth, it reports that a large number of debuginfo packages are
missing with messages like:
Missing separate debuginfo for /lib/libexpat.so.1
Try: yum --disablerepo='*' --enablerepo='*-debuginfo' install /usr/lib/debug/.build-id/f4/6a67411322c129b167dd758b8ab9cbd2e4ddf9.debug
When I attempt to run yum to carry this out, yum produces error messages
like:
file /usr/lib/debug/usr/bin/xmlwf.debug from install of expat-debuginfo-2.0.1-10.fc13.i686 conflicts with file from package expat-debuginfo-2.0.1-10.fc13.x86_64
Apparently, the debug info for the *library* /lib/libexpat.so.1 is
packaged in the same rpm with the debug info for the *executable* xmlwf.
And since executables on x86_64 system are not segregated by execution
model (32-bit vs. 64-bit) there is a file name conflict.
(A question) Is there any way to load the debug info for these 32-bit
library without removing the debug info for 64-bit libraries? This
would be tedious, since there are about 100 64-bit debug packages on the
system currently.
(A suggestion) On x86_64 systems 32-bit executables and 64-bit
executables should be in separate directories: say /usr/bin32
and /usr/bin/64. An addition directory /usr/bin would contain
(symbolic) links to default executables. (I think this would keep all
current shell scripts, etc., running.) Maybe the same file structure
-- /usr/lib32 /usr/lib64 and /usr/lib -- would also be good for
libraries.
All the best - jon
