I am learning how to make self-contained linux binary packages. I plan to make this the primary mode of distributing zhtools and CHAV. Please try this new zhtools version and let me know if you find *any* problems.
Installling for the binary distribution means unpacking to any place you like, then
setenv ZHTOOLS /path/to/zhtools
set path = ( $path $ZHTOOLS/bin)
in your .tcshrc (or equivalent in bash)
Note that if you use binary distribution, you can (are likely to) run into problems with the imcalc tool (a general fortran expression image calculator, not used for most cases), and also with linking your own code against the zhtools library. If you need those, install from source.
To install from source, edit zhconfig to add an entry which meets your needs, then
zhconfig your-mode
make
make install
Note that you need gcc with gfortran v>=4.6 to compile zhtools.
