libR.so: cannot open shared object file

Hello Everyone

I have been following this thread because I have similar issues with an
outside-of-R package.   The problem is related to dylib loading i.e. of
the form

Error in dyn.load(file, DLLpath = DLLpath, ...) :
   unable to load shared object
'/Users/stnava/code/gitANTs/ANTsR/src/ANTS/ANTS-build/lib/ANTsR/libs/libRantsRegistration.so':

dlopen(/Users/stnava/code/gitANTs/ANTsR/src/ANTS/ANTS-build/lib/ANTsR/libs/libRantsRegistration.so,
6): Library not loaded: libitkdouble-conversion-4.5.1.dylib
   Referenced from:
/Users/stnava/code/gitANTs/ANTsR/src/ANTS/ANTS-build/lib/libl_antsRegistration.dylib
   Reason: image not found

A solution that seems to work on both osx and linux is:

export
R_LD_LIBRARY_PATH=/Users/stnava/code/gitANTs/ANTsR/src/ANTS/ANTS-build/lib/

but I would really like to avoid this, if possible.    I tried using
.libPaths ( suspecting it would not work ) and I got the same error as
above ...

as an aside, there seems very little documentation for R_LD_LIBRARY_PATH
& I don't recall how I came across it ...  i have some other notes here:

https://github.com/stnava/ANTsR/blob/master/configure

any thoughts appreciated , at your leisure ...

& thanks, as usual,



brian

        just for completion

        i need to use
        library(Model, lib.loc="user/area/myRLib")
        because if i use
        library(Model)
        i get this message
        Error in library("BayesWrap") : there is no package called
        'BayesWrap'


    For the record: not if you follow my suggestion.

    See ?.libPaths for why.

            First of all, thanks for your help.

            I did all the things you told me. I was able to load the
            library, but
            then

            Error in dyn.load(file, DLLpath = DLLpath, ...) :
               unable to load shared object
            '/lustre/work/gjona2/Wrap/__BayesWrap/libs/BayesWrap.so':
               libR.so: cannot open shared object file: No such file or
            directory
            In addition: Warning message:
            package 'BayesWrap' was built under R version 2.15.2
            Error: package/namespace load failed for 'BayesWrap'
            Execution halted

            what does it means?

            G.M.

                        Suppose i have the package Model.tar.gz and my
                        writable are is in
                        user/area, what i have to do next to install the
                        package?


                    What I was picturing was something like this
                    (forgive me if syntax
                    isn't
                    100%):

                    mkdir user/area/myRLib
                    R CMD INSTALL --library=user/area/myRLib Model.tar.gz

                    and then in R:
                    library(Model, lib.loc="user/area/myRLib")

                    Note though Brian Ripley's response to me where he
                    indicates that this
                    is handled automatically.


                Yes,  install.packages("Model.tar.__gz") should suffice.
