Dear HelpeRs,
I am trying to use an thirdy-part library under Linux (the library is
developed
both for Windows and for Linux).
I have tried different solutions (with the library developer) but we are
not able to
solve the problem. So I try to ask for your help in order to escape from
the full stop
where we are at the moment.
The problem looks to depend on the dyn.load function (technical details
are below).
Thanks a lot for your work (it is an invaluable resource).
Best,
domenico
The library is called POP.R. I installed it but I have the following
error when
I try to load it:
---------------------------------------------------------------------------------------------------------------------------------------------
> library(POP.R)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'/usr/lib/R/library/POP.R/libs/ezlic20.so':
libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file
or directory
Error in library(POP.R) : .First.lib failed for 'POP.R'
---------------------------------------------------------------------------------------------------------------------------------------------
Nevertheless the file exists:
---------------------------------------------------------------------------------------------------------------------------------------------
> file.exists("/usr/lib/R/library/POP.R/libs/ezlic20.so")
[1] TRUE
---------------------------------------------------------------------------------------------------------------------------------------------
I tried also directly using the dyn.load function on the command line
(without and with the local flag):
---------------------------------------------------------------------------------------------------------------------------------------------
> dyn.load("/usr/lib/R/library/POP.R/libs/ezlic20.so",local=FALSE)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'/usr/lib/R/library/POP.R/libs/ezlic20.so':
libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file
or directory
> dyn.load("/usr/lib/R/library/POP.R/libs/ezlic20.so",local=TRUE)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'/usr/lib/R/library/POP.R/libs/ezlic20.so':
libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file
or directory
---------------------------------------------------------------------------------------------------------------------------------------------
In the lib directory there is also another library, for which I have a
different error
message using the dyn.load function (I have the same message using
local=FALSE):
---------------------------------------------------------------------------------------------------------------------------------------------
> dyn.load("/usr/lib/R/library/POP.R/libs/pop_BurSt.so")
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'/usr/lib/R/library/POP.R/libs/pop_BurSt.so':
/usr/lib/R/library/POP.R/libs/pop_BurSt.so: undefined symbol:
getChainedKeyId

Its a rather ancient copy of libstdc++ from Red Hat 6.2, which almost certainly doesn't exist in a normal Ubuntu installation. It used to be in Fedora as part of the compat-libstdc++-296-2.96 package, but Fedora dropped it around FC-4. So, either, you should convince whomever compiled that library to recompile it against a modern version of Linux (without any compat-* libs installed), made in the last 5 years, or you could find an old copy of the Fedora Core 4 RPM, unpack the libraries from the rpm, put them in /usr/lib, and hope that is the only ancient library you need. Hooray for closed source, eh? ~spot
