[McIDAS #MET-935016]: McIDAS - Cannot get mcunpack to execute -- keep getting message to define McINST_ROOT

Hi Alan,

OK.  For reference, 'make clobber' run in the ~mcidas/mcidas2005/src
directory cleans out anything left over from an attempted build.
You will be using this alot until the build is successful.

OK, this is what I was expecting on an initial build.

The fact that 'configure' checked for 'cc' means that it did not
find gcc.  If it had, the next line in ~mcidas/mcidas2005/tcl/unix/config.log
would have looked like:

configure:642: checking for gcc
configure:755: checking whether the C compiler (gcc -O ) works

I think that the PATH you have does not include the installation
directory for gcc.  In Fedora Core, gcc will be found in /usr/bin
_if_ a development environment has been installed.  The thing to
do now is to list out the PATH you have in place:

<login as 'mcidas'>
which gcc

'which' should tell you that gcc can be found in /usr/bin.  If
you get an indication that gcc was not found, it means one of
a couple of things:

- your PATH does not include /usr/bin
- gcc is not installed

To see if gcc is installed, run:

locate gcc

If this comes back blank, it likely means that gcc was not installed.
If 'locate' finds gcc, it means that your PATH is incomplete.  If
this is the case, add the following two lines to your .bashrc file
at the beginning of the file:

export PATH

The easiest thing to do at this point is logoff and login again.
After doing this, recheck to see if gcc is found using 'which':

which gcc

If gcc is still not found, your development environment is likely
incomplete and will have to be updated.

No worries.

By the way, I am willing to logon to your machine and poke around to
see what I can see if you like.  In order to do this, I would need
your 'mcidas' password; the fully qualified name of your machine;
and for your firewall to allow SSH connections from the unidata.ucar.edu
domain (128.117.140.*).  If you decide that you want me to login, please
send me the password in a different email than the machine name AND
do not reference the machine or account name in the email with the
