While I have been able to install rjags on my Windows computer, oddly I have
been unable to install rjags successfully on my 64-bit Linux compute server
(etch, Linux kernel 2.6.18). I am required to specify the JAGS module
directory upon installation; when doing this within R, I get:
install.packages("rjags",configure.args="--with-jags-modules=/usr/local/lib/JAGS/modules/")
which works fine, but then trying to load rjags gives an error:
library(rjags)
\Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared library
'/usr/local/lib64/R/library/rjags/libs/rjags.so':
libjags.so.1: cannot open shared object file: No such file or directory
Error : .onLoad failed in 'loadNamespace' for 'rjags'
Error: package/namespace load failed for 'rjags'
I'm not sure how to read this error. Does anyone have any suggestions?
It means that ld.so (the runtime linker) cannot find libjags.so.1.
Where is your libjags.so.1? My guess is that you installed it into
/usr/local/lib, since that is what you have for your module path. On a
64-bit Linux system it should be in /usr/local/lib64. (I had to tell the
JAGS installation that via libdir=/usr/local/lib64 on the configure line.)
R CMD ldd /usr/local/lib64/R/library/rjags/libs/rjags.so
will probably confirm that libjags.so.1 is not found.
If that is not the error, please note what the R posting guide says about
asking the maintainer.
