    Hello,

    I am trying (unsuccessfully) to compile the newest version (0.3.3) of Rkward. My distro is a SUSE 9.2.

    To configure Rkward I used:
    ./configure --with-extra-includes=/usr/lib/R/include --with-extra-libs=/usr/lib/R/lib/ --prefix=/opt/kde3/

    After that I did 'make', and got this error:
    ../rkward/rbackend/librbackend.a(rembedinternal.o)(.text+0x661): In function `RE
    mbedInternal::getCommandAsRealVector(char const*, int*, REmbedInternal::RKWardRE

    Any idea about what's going wrong? Any hit to solve this problem will be appreciated.

    Thanks, in advance,

      Please try this: In the file rkward/rkglobals.cpp, lines 33-35, remove the extern-keyword on each of those lines. I.e. they should read:

      char *RKGlobals::empty_char;
      char *RKGlobals::unknown_char;
      double RKGlobals::na_double;

      I believe/hope the extern definition is no longer needed, and likely it is what's causing those troubles.

        I deleted the extern keyword. After that I did a 'make clean' and ./configure. Then, I repeated 'make', but I got the same error :-(

          Oh dear. I've had those strange linkage problems before. No idea, why they occur (and why they are so erratic). Please try this: Insert the following lines to rkward/rkward.cpp below line 85 (which is another workaround for a similarily absurd problem):

              RKGlobals::empty_char = const_cast<char*> ("");
              RKGlobals::unknown_char = const_cast<char*> ("");
              RKGlobals::na_double = 0.0;

          Maybe this does the trick.

      Hi Javier,

      To me, it looks like the path to R headers is not the good one. However, we need more information. Could you please tell us the content of /usr/lib/R/include ? In addition, you could check where the R package that came with the distro put the headers? (your package manager should tell you that).

      Thanks for the report!

      Pierre

        Forget what I said, Thomas is probably right...

      For the record (after some private discussions with haakin): This problem shoud be fixed in rkward 0.3.4. If you run into this or a similar issue with rkward >= 0.3.4, please inform us about it.
