Re: ncl: error while loading shared libraries

Hi again,

With the "ncargex cpex08" command, it looks like it can't find the X11
library on your system.

You need to either install the X11 development libraries, or else figure
out where they reside on your system and use the "-L" option to help
ncargf77 figure out where they are.

For example, if the "libX11.so" file is in /opt/local/lib, then you
would need to do something like this:

    ncargex cpex08 -n
    ncargf77 -o cpex08 -L/opt/local/lib cpex08.f cpexcc.f
    ./cpex08

If you are on a Linux system, you can find the X11 library with:

     locate libX11.so

I already uninstalled/installed again everything with the correct
libraries, set the LD_LIBRARY_PATH, LD_RUN_PATH, and when i run:

$ldd $NCARG_ROOT/bin/ncl
         linux-gate.so.1 => (0xffffe000)
         libnc-dap.so.3 => /usr/local/lib/libnc-dap.so.3 (0xb7ecf000)
         libdap.so.6 => /usr/local/lib/libdap.so.6 (0xb7e03000)
         libdapclient.so.1 => /usr/local/lib/libdapclient.so.1 (0xb7dc7000)
         libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7db5000)
         libidn.so.11 => /usr/lib/libidn.so.11 (0xb7d85000)
         libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7d81000)

         libXext.so.6 => /usr/lib/libXext.so.6 (0xb7c86000)
         libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7c61000)
         libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7b7c000)
         libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7b71000)
         libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7a40000)
         libssl.so.6 => /usr/lib/i686/cmov/libssl.so.6 (0xb7a01000)
         libcrypto.so.6 => /usr/lib/i686/cmov/libcrypto.so.6 (0xb78c6000)
         libcurl.so.4 => /usr/local/lib/libcurl.so.4 (0xb7894000)
         libxml2.so.2 => /usr/local/lib/libxml2.so.2 (0xb7769000)

         libz.so.1 => /usr/lib/libz.so.1 (0xb774c000)

and then, I run ncl:

ncl 0>

it works!! :D thanks!! at least!! i had some problems with the
libssl.so.6 and libcrypto.so.6, the only ones that i found was the
libssl.so.0.9.8 and the libcrypto.so.0.9.8. I just:
  $cp libssl.so.0.9.8 libssl.so.6
Its nasty but it worked :).

I just have a problem running the NCAR Graphics test:
$ncargex cpex08

NCAR Graphics Fortran Example <cpex08>

   Copying cpex08.f

   Copying cpexcc.f

Compiling and linking...
g77 -fPIC -fno-second-underscore -O -o cpex08 cpexcc.f cpex08.f
-L/usr/local/lib -lncarg -lncarg_gks -lncarg_c -lX11 -lXext
/usr/bin/ld: no se puede encontrar -lX11
collect2: ld devolvió el estado de salida 1

The compile and link failed.

Well, thats all! thanks for everything Mary :D!
