[Met_help] Problem with running the make script for METv0.9

Helmut,
It still looks like there's an issue getting the MET code to link to the NetCDF library.
There are a couple of things you could do to try to debug that.
First, you could make sure that the NetCDF library archive file looks OK. The tool "nm" (on my system, and hopefully on Solaris as well) can be used to dump the contents of a library archive file.
So first locate the file "libnetcdf_c++.a" in your netCDF distribution. And try: nm libnetcdf_c++.a
This will list all of the symbols defined in that library archive file. And you can use grep to pick out and make sure specific ones are there. So: nm libnetcdf_c++.a | grep is_valid
Will look for symbols containing the function name is_valid. Now there will likely be some compiler "garbage" characters before and/or after the is_valid symbol, but that's getting beyond my
expertise. But if "is_valid" is not defined in your file "libnetcdf_c++.a" then you still have troubles with your netCDF library.
And when you compile MET, you could try turning on some debug trace for the linker. You'll have to look at the man page for the compiler (g++) and the linker (ld on my system) to figure out exactly
what options to use.
In my top-level MET Makefile, I changed the Flags lines as follows:
FROM: FLAGS = -g -Wall -Wshadow -static
TO: FLAGS = -g -Wall -Wshadow -static -Xlinker -t
This passes the "-t" option on to the linker, which turns on trace output for the linker. Then you could see which netCDF you're linking to, to make sure you're actually linking to the version that
you think you are rather than some other version of netCDF on your system. You can look at the other compiler and linker options on their man pages to look for others that might help as well.
Sorry I can't be of more help.
