AMBER md/g95/gfortran issue
Hi,
i am trying to install AMBER10 which is a molecular dynamcis package onto two linux red hat pcs. I can successfully install the tools that comes with which uses gcc to compile, however AMBER10 requires either g95 or gfortran to compile. This is where the issue lies, i have installed both gfortran and g95 and and try to compile and i get this response,


./configure_amber gfortran
Setting AMBERHOME to /usr/local/amber10

Setting up Amber configuration file for architecture: gfortran
Using parallel communications library: none
The MKL_HOME environment variable is not defined.

Testing the C compiler:
gcc -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -O2 -m32 -o testp testp.c
OK

Testing the Fortran compiler:
gfortran -O0 -fno-range-check -fno-second-underscore -o testp testp.f
./configure_amber: line 1168: gfortran: command not found
./configure_amber: line 1169: ./testp: No such file or directory
Unable to compile a Fortran program using gfortran -O0 -fno-range-check -fno-second-underscore
Please check your compiler settings or configure flags.

I have set path = $path .... in my .cshrc and i when i type g95 by itself i get,

Fatal error: need a file to compile

Not sure whats happening any help is greatly appreciated. Thanks

LEARN ABOUT DEBIAN

builder-cc

BUILDER-CC(1)							 Debian GNU/Linux						     BUILDER-CC(1)

NAME

       builder-cc - gcc wrapper to facilitate pentium-optimizations

SYNOPSIS

       export DEBIAN_BUILDARCH=architecture
       export DEBIAN_BUILDGCCVER=gcc-version
       gcc ...

DESCRIPTION

       The  builder-cc	wrapper is normally used by calling gcc as usual. If the environment variable DEBIAN_BUILDARCH is not set, builder-cc does
       nothing, and the real gcc is invoked with the specified arguments.

       When the DEBIAN_BUILDARCH environment variable is set, builder-cc invokes gcc with the  specified  arguments,  plus  -mcpu=DEBIAN_BUILDARCH
       -march=DEBIAN_BUILDARCH	This  has  the effect of telling gcc to use architecture-specific optimizations without changing the command line.
       This is particularly useful for package builds.

       If DEBIAN_BUILDGCCVER is not set, builder-cc calls  gcc.real.   If  DEBIAN_BUILDGCCVER  is  set,  builder-cc  calls  gcc-DEBIAN_BUILDGCCVER
       instead.

ENVIRONMENT

       DEBIAN_BUILDARCH
	      If set, the architecture to compile for. Useful values are pentium or pentiumpro.

       DEBIAN_BUILDGCCVER
	      If set, the version of gcc to be invoked. Useful values are 3.0 or 2.95.

NOTES

       The real gcc is renamed gcc.real, and a diversion is registered with dpkg-divert(1).  Thus builder-cc's idea of the default gcc is dictated
       by whatever package installed /usr/bin/gcc.
