dyn.load problem under linux
Some additional notes inserted below.

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

We have seen that problems like this can arise if there is a mixture of 32-bit and 64-bit items. Everything here is definitely 32-bit.
--------------------------------------------------------------------------------------------------------------------------------------------- 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
This error message is actually good news -- it finds the file (sitting right next to the one it can't "find") and gets so far as to find a symbol that is in the first file. That is, this command appears like it would work if the first load worked.

I'm not sure what versions of Linux other clients have (it's never been an issue before), but I know it works in Suse. Pat
