Howdy Jim!

I hope that fusion is going well there - I'm depending on it for some cool 
spaceships. ;-)

Adding a library can also be done (without modifying any files) by setting 
environment variable LIBS before running configure. (In bash: LIBS=-lfst 
./configure && make check).

Some compilers seem to require some special library to find this function. I am 
not sure why this happens, or what to do about it. I suspect that it really 
means there is some slight problem with the compiler installation (because the 
compiler should supply this function without any involvement on the part of the 
user.)

Do you also have to add this when compiling your applications? That is, if you 
have a fortran applcation without netCDF, do you have to include -lfst in its 
build flags?

Thanks,

Ed

Thanks Jim!
