libstdc++
library
requirement
While running the SPS Installation setup script, you may encounter a message
regarding a failed dependency requirement for a libstdc++ library. This library is
provided in one of several compat-libstdc++ rpm packages, depending on the
hardware platform and Linux distribution you are running. Even on 64-bit systems,
LifeKeeper requires the use of the32-bit architecture package rather than the 64-bit
version (x86_64) and will fail to start due to a missing required library if the64-bit
architecture version isinstalled.
To avoid (or resolve) this problem, install the 32-bit architecture version of the
compat-libstdc++ package found on the OS installation media and run (or re-run) the
I/S setup script. Note that some distributions also carry more than one 32-bit
version of this package (e.g. compat-libstdc++-296-2.96-132.7.2 and compat-
libstdc++-33-3.2.3-47.3). In this situation, simply install both versions to ensure
that the required library is installed.
libXp and
libXt library
requirement
s
Similar to the item above, you may also encounter installation messages regarding
failed dependency requirements for the libXp and libXt libraries. LifeKeeper requires
the 32-bit versions of these libraries, even on 64-bit platforms.
