Create the csrch directory structure with gzip -d csrch.tar.gz tar -xvf csrch.f This produces the directory csrch and the subdirectory source. 2. Change directories to csrch and install csrch with make install This creates libraries in each of the subdirectories 3. Create the executable csrch.x with make csrch and run the sample problems by executing csrch 4. Compare the output in csrch.out with the output in csrch.sun4 ***************************************************************** ADDITIONAL INFORMATION J. J. More' and D. J.
