Greetings --
This has also been posted on the jags forum, but since I suspect the
problem is more 'R-related' than jags, will aos post here.
Decided to 'upgrade' from jags 3.x.x to 4.x.x today, on my GNU/Linux
boxes (which run latest RHEL). Here are the basic details:
1\ used R 3.2.2 compiled from source. 64-bit -- nothing fancy, other
than the fact that I used OpenBLAS instead of 'generic'. Works fine.
2\ downloaded and compiled JAGS 4.0.1 from source (nothing fancy,
./configure & make & make install) -- no errors. Runs fine as a
standalone app from CLI.
3\ Downloaded rjags_4-3.tar.gz, and installed from R CLI (within R --
usual R CMD INSTALL approach). Again, no errors reported.
However, when I fire up R, and try something simple like
library(R2jags)
I get a whole slew of error messages - following is reproducible on
all my machines:
Loading required package: rjags
Loading required package: coda
Error : .onLoad failed in loadNamespace() for 'rjags', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object
'/usr/lib64/R/library/rjags/libs/rjags.so':
libjags.so.3: cannot open shared object file: No such file or directory
Error: package ‘rjags’ could not be loaded
Further puzzlement -- I uninstalled R2jags and rjags, with the idea that
re-installing them (ostensibly with the 'latest and greatest') would do
the trick. While the process went fine for R2jags, when I tried to
re-install rjags, got the following error messages:
checking for gcc -m64 -std=gnu99 option to accept ISO C89... none needed
checking for jags_version in -ljags... yes
checking version of JAGS library... wrong version
configure: error: rjags requires JAGS version 4.x.y
ERROR: configuration failed for package ‘rjags’
* removing ‘/usr/lib64/R/library/rjags’
* restoring previous ‘/usr/lib64/R/library/rjags’
Hmm, is it possible, that your JAGS 4.x.y installation is fine, but an
old libjags.so library is lying around from a not fully completed
deinstallation? Could you have a look for older libjags.so versions,
please?
Just a thought.
I suppose thats possible -- I'll go through the sequence again at some
point, and report back.
