    I've been struggling with getting the ncarg4.2.3 to compile with the Intel
    Fortran compiler (=ifc).

    I've run into some syntax errors that I've been trying to fix.

    The first one I found/fixed was in
    /ncarg-4.2.3/ncarg2d/src/libncarg/ngmisc/ngdots.f

    I got the following error:
    #################################################################
    make[5]: Entering directory
    `/usr/local/ncargraphics/ncarg-4.2.3/ncarg2d/src/libncarg/ngmisc'
    ifc -O -c -o ngdots.o ngdots.f
       external subroutine NGDOTS

          SAVE IFIRST
          ^
    Error 134 at (52:ngdots.f) : The attribute SAVE already applies to all
    variables
    1 Error
    compilation aborted for ngdots.f (code 1)
    make[5]: *** [ngdots.o] Error 1
    make[5]: Leaving directory
    `/usr/local/ncargraphics/ncarg-4.2.3/ncarg2d/src/libncarg/ngmisc'
    ##################################################################

    I used the error report to infer that I should just comment out line 52
    that says:
          SAVE IFIRST

    That allowed a lot of portions to compile that weren't previously
    compiling.

    I'm having some problems with my next fix though. I'm trying to fix
    several errors that read like:
    ###################################################################

    Appearently the getarc and iargc subroutines are in add-on libraries in
    Intel fortran. And this is were I am running into trouble. I need to
    force the option "ifc -Vaxlib". I'm not getting the instructions in the
    INSTALL file to work for me.

    I can run ./Congifure -v

    and the output from make Info is:
    ----------------------------------------------------------
    f77 Compiler ifc
    f77 Flags -O
    C Compiler gcc
    cc Flags -ansi -O -I./include -I/usr/X11R6/include
    -I/usr/include -DSYSV -D_POSIX_SOURCE -D_XOPEN_SOURCE -DByteSwapped
    -DNeedFuncProto
    -------------------------------------------------------------

    so I need to modify the f77 Flags. When I modify the
    ncarg-4.2.3/config/LINUX file to have the line

    #define FcOptions -Vaxlib
     
    and then do make Info I get the same results as above.

    When I modify ncarg-4.2.3/config/Makefile as well to read

     FCOPTIONS = -Vaxlib

    I still get the same results from make Info. I can't seem to force the
    new flags to be recognized, or that is what "make Info" is telling me.

    Do I need to do something special to the files for the changes to be
    recognize? I'm running on a RedHat 7.1 machine.

    Thanks
    Erika
