Hi Stewart, Sorry to take so long to get back to you on your MacOS-X problem. Building MciDAS under MacOS-X is a bit tricky as you have found out. At the current time, our MacOS-X developoment machine (actually our only MacOS-X box) is not functioning, so I am unable to work through the steps you need to take to get things working on your end. If the development environment is installed in a standard way, then the following advice from SSEC (and in the McIDAS Users Guide) should be helpful: http://www.unidata.ucar.edu/software/mcidas/2005/users_guide/PreparingtheWorkstation.html#25760 Renaming the g77 library on Mac OS X On Mac OS X systems, a collision can occur between the g77 version of the libgcc.a file and the Apple-supplied file of the same name. To resolve the conflict, the system administrator should run the three commands below to rename the file to libgcc_g77.a in the /usr/local/lib/gcc/powerpc-apple-darwin7.2.0/3.4.0/ directory and create a link to it in the /usr/local/lib/ directory. Note that the version numbers in the directory path may be different on your system. Type: cd /usr/local/lib/gcc/powerpc-apple-darwin7.2.0/3.4.0 Type: mv libgcc.a libgcc_g77.a Type: ln -s libgcc_g77.a /usr/local/lib/ You should not have to edit any of the McIDAS build files (e.g., makefile or mccomp.sh). If this tip does not get you going, I can login to your system to scope things out. In order to do this, I would need the 'mcidas' password (and possibly 'root') sent to my private email address: address@hidden If you decide that you would like me to login, please send the password ** without any reference to the account name or machine name ** to the above address in one email and the machine name in a separate email.
