INSTALL ======= Unpack the zip file into some "install" directory; e.g. /home/user/timm/opt/clam/1.0 To use the code in that install directory, do nothing else. To allow multiple users to access this code, tell them to copy the "Makefile" to their local directory, then change the Root= $(shell pwd)# to point to the install directory; e.g. Root=/home/user/timm/opt/clam/1.0 After that, go to the directory with the Makefile and type make ready If you see no crashes, then try the following (that could take a little while to run): make score If all is working, this should report many "PASSES" and no "FAILS".
