[McIDAS #ZOK-961273]: Compiling McIdas - not as user mcidas?

Hi Mike,

Very good.  Presumably you followed the procedures listed in the Unidata 
McIDAS-X
Users Guide for setting up entries in your shell-specific definition file (e.g.,
.cshrc for C Shell users; .bash_profile for BASH, etc.)?

The only thing 'magical' about an account named 'mcidas' is that several things
in McIDAS will default to one or more directories under ~mcidas unless "told" 
not
to do so.

> setting my environment as follows:
> 
> setenv McINST_ROOT /d3/dixon/downloads/mcidas
> setenv VENDOR -gfortran
> setenv MCHOME $HOME/mcidas
> setenv MCDATA /d3/dixon/data/mcidas

I believe you need to follow the same procedure that is defined in the Unidata
McIDAS-X users guide.

In particular:

- since you are essentially saying that you want McIDAS installed in the 'dixon'
  account, MCHOME is likely to be needed to be defined as 
$HOME/downloads/mcidas OR $HOME

- the recommended additions to one's shell-specific definition file (again, 
.cshrc for C
  Shell, .bash_profile for BASH, etc.) force the sourcing of files that define 
all of
  the needed environment variables upon login.  One of the environment 
variables defined
  is CC; another is CXX (set to blank since McIDAS does not use C++ bindings 
for any
  routines); another is FC; etc.  These are defined so builds can be done 
easily.  Your
  success building as the user 'mcidas' attests to this.

I also see another problem:

make[2]: Entering directory `/d3/dixon/downloads/mcidas/mcidas2008/tiff/port'
/usr/lib/gcc -O -I. -I../port -c -o strcasecmp.o strcasecmp.c
make[2]: execvp: /usr/lib/gcc: Permission denied
make[2]: *** [strcasecmp.o] Error 127

This seems to say that /usr/lib/gcc can not be execed.

> Can you suggest how I might get around this?

Try following the instructions from the Users Guide.  Since you are doing the 
build
in your own account (or elsewhere), you will need to modify the additions you 
make
to your shell-definition file.

Questions:

- are you attempting to build McIDAS in your own account

- if yes, is the HOME directory of your account /d3/dixon/downloads

- if now, what is the setup for the account you are trying to use

Cheers,

Tom
