Since you have to link against the McIDAS library to build ldm-mcidas from source, and since netCDF 3.5.0 gets built with McIDAS, I recommend that you use the netCDF stuff (libnetcdf.a and netcdf.h include file) in the McIDAS distribution. To do this, you will need to: 1) run 'make distclean' from the top level directory where you are attempting to build ldm-mcidas v2002b 2) define environment variables that will tell configure where to look for the version of the netCDF bundled with McIDAS. These environment variables will depend on the set of compilers you built McIDAS with. The choices on Linux are gcc/mcfc/f2c or gcc/g77. If you built McIDAS using the gcc/g77 combination, the environment variable settings you would use are: # Defines needed for netCDF build using gcc/g77 setenv CC gcc setenv CPPFLAGS "-DNDEBUG -Df2cFortran" setenv CFLAGS -O setenv FC g77 setenv FFLAGS "-O -Wuninitialized -fno-automatic" setenv CPP_MCIDAS '-I/home/mcidas/inc' setenv LD_MCIDAS '-L/home/mcidas/lib -lmcidas' setenv CXX This assumes that you installed McIDAS in /home/mcidas. If your installation is different (and I believe yours is), you will need to adjust CPP_MCIDAS and LD_MCIDAS. Next, the netCDF stuff. Again, if you installed McIDAS in /home/mcidas, the environment variables needed for the netCDF would look like: setenv CPP_NETCDF -I/home/mcidas/include setenv LD_NETCDF '-L/home/mcidas/lib -lnetcdf' Again, you may have to adjust these to match your McIDAS installation. You will also have to specify CPP_LDM and LD_LDM to locate the LDM include and library files, respectively. The settings for these environment variables will depend on how you installed the LDM on your machine. If you installed in /usr/local/ldm, then the settings would look like: setenv CPP_LDM -I/usr/local/ldm/include setenv LD_LDM '-L/usr/local/ldm/lib -lldm' Lastly, you may have to define LD_X11. I use: setenv LD_X11 '-L/usr/X11R6/lib -lX11' After these are defined correctly in your enviornment, you need to rerun configure. Note that you must do the 'make distclean' like I said above before you can rerun configure. If you don't run 'make distclean', configure will used cached values for the environment variable settings I list above. So, run: ./configure make make test At this point, you should have working ldm-mcidas v2002b executables. Or, you could simply download the binary distribution of ldm-mcidas that I make available. The direct FTP location of the distribution for RedHat 8.0 Linux is: <login as 'ldm'> cd ~ldm ftp ftp.unidata.ucar.edu <user> anonymous <pass> address@hidden cd pub/binary/linux8_2.4-i686 binary get ldm-mcidas-2002b.tar.Z quit tar xvzf ldm-mcidas-2002b.tar.Z cd ldm-mcidas-2002b/bin <copy the ldm-mcidas decoders you are using to the directory you are using them from> As a last note, I am just about to release an addendum for McIDAS v2002 that contains bug fixes for the McIDAS-XCD data monitor DMSYN. The mods fix a problem first noted on RedHat 8.0 Linux where dmsyn.k will chew up all available CPU. The bug fixes can only be used with McIDAS v2002, so if you are still running McIDAS 7.8x, you may well have problems that can only be fixed by upgrading your version of McIDAS. Tom
