[McIDAS #CHP-794471]: ** Linker Flags - Solaris 2.10 build of McIDAS 2005

Hi Jim,

Sorry I was not able to respond yesterday...

This is a configuration that we are not (yet) running here at the UPC, so
please keep that in mind when interpreting my comments.

OK.

GCC should know where it was installed, so it seems odd to me that it
does not know where to find one of its own libraries.  Was the GCC directory
structure modified after the installation?

OK.

You will have to make modifications in two places:

- the enviornment through setting CFLAGS, etc.

- in ~mcidas/mcidas2005/src/mccomp.sh

The are not.  This is why you will need to modify mccomp.sh.

Correct.  The flags needed for various OSes and compilers for
the core McIDAS code are set in mccomp.sh.

Yup.

You will need to edit the file.  Look for the 'SunOS' section (starts
at about line 748).  You will see a comment about setting some compiler
independent flags, and then a section for version 5 of the OS.  I think
you should add your defines in the same way as the other defines that
are already there:

                #-------
                # Note: you must include a corresponding -R option for
                # each -L option for directories where shared libraries
                # are found.
                #
                # The /usr/dt directories are where Motif gets installed
                # in Solaris 2.4.
                #-------

                I_opts="$I_opts -I/usr/dt/include"
                L_opts="$L_opts -R/usr/dt/lib"
                L_opts="$L_opts -L/usr/dt/lib"

                I_opts="$I_opts -I/usr/openwin/include"
                L_opts="$L_opts -R/usr/openwin/lib"
                L_opts="$L_opts -L/usr/openwin/lib"

                I_opts="$I_opts -I/usr/local/include"
                L_opts="$L_opts -R/usr/local/lib"
                L_opts="$L_opts -L/usr/local/lib"


> Any suggestions would be most appreciated.

Please try editing mccomp.sh and let me know if you run into any
problems.

One last comment:

The 'make' process converts mccomp.sh (a template) into mccomp (an
executable shell script).  Please make sure to make your modifications
in mccomps.sh not mccomp.

Cheers,

Tom
