Hsie,

The problem is in the environment variables you did or did not set
before starting the build.  The configure script that builds the
Makefile for the jpeg stuff is dumb.  It defaults to using 'c' as the C
compiler.  Setting needed environment variables insures that this does
not happen.

The list of environment variables you should set before building McIDAS
are listed in:

Review System-specific Notes and Warnings
http://my.unidata.ucar.edu/content/software/mcidas/2003/mcx/warnings_mcx.html

Here is the set that should work for your 'VENDOR' environment:

setenv CC /opt/SUNWspro/bin/cc
setenv CPPFLAGS -DNDEBUG
setenv CFLAGS -O
setenv FC /opt/SUNWspro/bin/f77
setenv FFLAGS "-O -erroff=WDECL_LOCAL_NOTUSED"   # "-erroff=..." turns
                                                 # off an ignorable warning.
                                                 # Your compiler may differ.
setenv CXX " "
setenv F90 " "

Note that  setting CXX and F90 to a blank stops the build of the netCDF
C++ and F90 interfaces.  Neither of these is used by McIDAS, so this
does not hurt anything.

 ...

>I need your help.

Set the environment variables as indicated above in your shell-specific
definition file (e.g. .cshrc for C shell, etc.), make sure that the
settings are active (e.g., source ~/.cshrc, etc.), clobber the first
build attempt (e.g., 'make clobber') and then start the build again.

Cheers,

Tom
