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 --------------------------------------------------------------------------------------------------------------------------------------------- My operating system is Ubuntu 6.10 - Edgy.
