%zcat wise2.1.12b.tar.gz | tar -xvf -
This will untar into a directory called 'wise2.1.12b' (of course, your version of Wise2 might be different).
Once you have made the tar file, it should build completely cleanly as long as you have an ANSI C compiler. If in doubt, just assumme that it is, but in particular sun users might want to use gcc (gnu cc) as the sun cc compiler installed by default is often non-ANSI. To change the cc compiler you only need to edit the line in the top level makefile called CC = cc to CC = gcc.
To build the package type
%cd wise2.1.12b %make all %make bin
The executable files will now be in wise2.1.12b/bin
I am interested in all compiler errors, and consider most of them to be bugs (which means if you report them you could be on the champagne list!)
