Installing cc and f77 requires other files than just the cc and f77
executables, for example the run-time libraries, and the assembler (I
think that's what "acomp" is).  The configure script in "checking c
compiler" is just trying to compile and run a very simple C program.
If it cannot do this, it produces the error message above.

Rather than trying to use "cc" and "f77" by just copying some files
from a system that has them, I suggest you use gcc, if it works for
compiling C programs.  If you need Fortran for GMT (netCDF doesn't
really need a Fortran compiler to just build the C interface), you
might be able to use "fort77" for the Fortran compiler (which is just
a script that uses the f2c program that translates Fortran to C).

To use "gcc" for building netCDF, just run "make clean" in the netCDF
source directory, then "rm config.cache" if that file is still there.
set the environment variable "CC" to "gcc" and set "FC" to ""
(nothing) to indicate you don't need the Fortran interface to netCDF
built.  Then just run the "configure" script, "make all", "make test",
and finally "make install" if needed.  I just tested this with version
2.8.1 of gcc on a Solaris 2.7 system, and it worked fine.

I can't answer questions about GMT; if it requires the Fortran
interface for netCDF, you will need to get f2c (which I believe
includes the fort77 script) or maybe g77 will work.

I'm not sure, maybe the GMT support staff can help with that.
