Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.15) Gecko/20101027 Fedora/3.0.10-1.fc12 Thunderbird/3.0.10 |
Previously, the package file for UHD placed the UHD shared libraries in
/usr/local/lib, even on x86_64
systems, where Fedora prefers libraries in /usr/local/lib64.
So, if you'd modified your /etc/ld.so.conf.d to have a configuration for
/usr/local/lib, then your
code would link with the instance of /usr/local/lib/*uhd*.so*.
Recently started UHD correctly
placing .so files in the preferred location on Fedora on x86_64
systems (/usr/local/lib64).
But because of search-order issues, the dynamic loader would find the
ones in /usr/local/lib first,
which become more and more obsolete. The "cure" is to remove the old
libuhd*.so* files from
/usr/local/lib on x86_64 systems, and re-run "ldconfig", which will
cause it to find the newer ones
(now correctly placed) under /usr/local/lib64.
Just tripped over that one this morning, and thought I'd share my
experience.
