Hi Samuel, The indications from config.log coupled with the 'env' output you sent yesterday are that the C++ development environment on the machine you are trying to build McIDAS on is incomplete. The following from config.log best demonstrates this conjecture: configure:6683: /usr/bin/cpp -I/usr/include/rpc -DNDEBUG -Df2cFortran -I/home/mcidas/mcidas2007/hdf/../zlib -I/home/mcidas/mcidas2007/hdf/../jpeg conftest.cc cpp: error trying to exec 'cc1plus': execvp: No such file or directory configure:6689: $? = 1 The important part of this snippit is the line: cpp: error trying to exec 'cc1plus': execvp: No such file or directory So, it appears that you or the system admins for this machine need to update the development environment using something like: yum update gcc-c++ (update or install) After the C++ installlation is updated or installed, you should try the McIDAS build from scratch: <as 'mcidas'> cd ~mcidas/mcidas2007/src make clobber make Cheers, Tom **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
