    Hello,

    I don't know why I seem to be having such trouble with this (if I did, I
    wouldn't bother you about it, I suppose!), but I can't get rjags to detect my
    JAGS installation properly.

    I'm running Ubuntu 11.10 and have admin status. I installed JAGS 3.2.0 from
    source, using the standard directory structure (i.e., prefix=/usr/local). My
    JAGS installation works perfectly fine when I run standalone JAGS scripts.

    Which is why I'm confused that I can't seem to get rjags to install correctly.
    I've tried passing various directory arguments via configure.args, but to no
    avail. I invariably get the following output when trying to install rjags:

    > install.packages('rjags')

    produces exactly the same results as above. I just can't seem to be able to
    get rjags to find libjags.so.3 (despite the fact that it is clearly in
    /usr/local/lib).

    I'm afraid I have no clue why the rjags installation should fail. Given the
    simplicity of the task, I feel like I am missing something incredibly obvious.
    In any case, I would appreciate any assistance.

    Many thanks!

    Maybe this is not the correct path, but have you tried to force R to install
    dependencies with "install.packages("rjags", dependencies=TRUE)"?

    Well, at least I can take solace in the fact that I was right in saying that I
    was missing something obvious. That did the trick--many thanks, xevi!

    Hi plasmoidal,

    I am having the same problem that you had. It seems rjags just cannot find
    libjags.so.3, even though it is clearly in /usr/local/lib. But adding dep=TRUE
    doesn't seem to solve my problem. And I am having a hard time understanding
    why it would. The only dependency is coda package, which I have installed. Am
    I also missing something obvious here? Many thanks!

    Two possibilities spring to mind:

    1) The directory /usr/local/lib is not on the default linker path. Try
    "/sbin/ldconfig -p | grep jags". If you don't see anything then you need to
    add /usr/local/lib to your linker path by editing /etc/ld.co.conf and then run
    /sbin/ldconfig as root to update it.

    2) You are working with 64-bit R and JAGS but have installed JAGS in the wrong
    place. If R is in /usr/lib64/R then rjags expects to find JAGS in
    /usr/local/lib64 not /usr/local/lib.

    Martyn,

    Thank you very much! It is the first situation. I am playing with Arch Linux
    and it doesn't include /usr/local/lib in the default linker path.

    Hi,

    I kind of have a similar problem, but can't figure out how to make it work.

    I have used a non-standard location, since I don't have write permission in standard directories.
    the installation of JAGS is in "/perm/hechtmay/JAGS/JAGS-3.3.0"
    the 64bit library is in "/perm/hechtmay/JAGS/JAGS-3.3.0/lib64"

    The operation system ist "RedHat EL 5"



    when I try to install 'rjags' package

    install.packages( pkg = "rjags", lib = "/perm/hechtmay/R/R-3.0.1/library", repos = "http://cran.us.r-project.org" , configure.args = "--with-jags-include=/perm/hechtmay/JAGS/JAGS-3.3.0/include/JAGS --with-jags-lib=/perm/hechtmay/JAGS/JAGS-3.3.0/lib64", dependencies=TRUE )
    



    this error occurs:

    Warning: namespace ârjagsâ is not available and has been replaced
    by .GlobalEnv when processing object âLINEâ
    ** testing if installed package can be loaded
    Error : .onLoad failed in loadNamespace() for 'rjags', details:
      call: dyn.load(file, DLLpath = DLLpath, ...)
      error: unable to load shared object '/perm/hechtmay/R/R-3.0.1/library/rjag/libs/rjags.so':
      libjags.so.3: cannot open shared object file: No such file or directory
    Error: loading failed
    Execution halted
    ERROR: loading failed
    



    both suggestions won't work

    [1] if I run "/sbin/ldconfig -p | grep jags", it's blank
    but i cannot run /sbin/ldconfig

    [2] i don't have write permission in /usr/local/lib64

    what can I do to make it work?

    Add the option --enable-rpath to configure.args. This will hard code the location of the JAGS library into rjags so that rjags can find it, even though it is in a non-standard location.

    install.packages( pkg = "rjags", 
      lib = "/perm/hechtmay/R/R-3.0.1/library", 
      repos = "http://cran.us.r-project.org" , 
      configure.args = "--with-jags-include=/perm/hechtmay/JAGS/JAGS-3.3.0/include/JAGS --with-jags-lib=/perm/hechtmay/JAGS/JAGS-3.3.0/lib64 --enable-rpath", 
      dependencies=TRUE)
    

    I have made some changes to rjags_4 (not yet released) that should make it easier to negotiate the problems with non-standard installations.

      Huaiying,

      Don't worry about installing JAGS and rjags from source on Ubuntu. Go
      to these two Launchpad PPAs:

      https://launchpad.net/~marutter/+archive/rrutter
      https://launchpad.net/~marutter/+archive/c2d4u

      You really only need the first one, but the second one has a 1000 more
      packages for R that may be useful. Once you have insalled those two
      PPAs as per the instructions on those pagesm do the following:

      sudo apt-get update
      sudo apt-get install r-cran-rjags

      rjags will be installed, as well as JAGS if needed and anything else.
      You should be good to go. The only hang-up would be if you need to have
      JAGS installed in a strange location or you don't have sudo rights. Let
      me know if that is the case.

      Hope this helps,
      Michael

    Hi,

    I'm trying again (see my post from 2013 above) to install rjags, this time with R version 3.2.3 and JAGS version 4.1.0 .

    I still don't have any root privileges, the operating system is CentOS release 5.6 .

    I configured JAGS this way:

    ./configure --prefix=/perm/hechtmay/JAGS/JAGS-4.1.0 --libdir=/perm/hechtmay/JAGS/JAGS-4.1.0/lib64
    make
    make install
    

    The directory looks like this:
    /perm/hechtmay/JAGS/JAGS-4.1.0]

    drwx------ 2 hechtmay eins 3864 Feb 9 21:51 bin
    drwx------ 3 hechtmay eins 3864 Feb 9 21:51 include
    drwx------ 4 hechtmay eins 3864 Feb 9 21:51 lib64
    drwx------ 2 hechtmay eins 3864 Feb 9 21:51 libexec
    drwx------ 3 hechtmay eins 3864 Feb 9 21:51 share

    Now I am trying to install rjags with just the --with-jags-prefix option:

    /perm/hechtmay/R/R-3.2.3/bin/R CMD INSTALL --configure-args=--with-jags-prefix=/perm/hechtmay/JAGS/JAGS-4.1.0 /work/hechtmay/R/install_R_package/targz/rjags_4-4.tar.gz
    

    The error is:
    configure: error: rjags requires JAGS version 4.x.y

    This is the entire output:

    The latest version of the rjags package is rjags_4-5. Please use that version.

    Configuration of rjags has changed since 2013. The preferred method is now to use pkg-config.

    export PKG_CONFIG_PATH=/perm/hechtmay/JAGS/JAGS-4.1.0/lib64/pkgconfig
    R CMD INSTALL --configure-args='--enable-rpath' rjags_4-5.tar.gz
    

    The INSTALL file that comes with the rjags tarball has details.

      Thank you so much for your super fast response! It works :-)

      Just another note for me (for future - hopefully less time-consuming - attempts):
      use setenv instead of export (since export is not available)

      setenv PKG_CONFIG_PATH /perm/hechtmay/JAGS/JAGS-4.1.0/lib64/pkgconfig

    I've been struggling to get rjags installed on my mac (OS 10.10) for the past few days. I installed JAGS via macports and via the dmg file on the source forge page, but still get the same error whenever I try to install rjags via install.packages() or via devtools::install_url(). Below is the output from install.packages("rjags", dependencies = T) on my machine.
