`make install' is used to install (copy) the files necessary for using CDF into directories named `lib', `include', and `bin' (these directories will be created if necessary). The only optional `make' variable is as follows... INSTALLDIR= where is the directory path of where the `lib', `include', and `bin' directories exist or will be created if necessary. If this is not specified, a default path of `.' is used (which specifies the current directory level). For example, to install the CDF distribution at the current directory level enter the following... make install If you wanted to install the distribution at a different location, for instance `/usr/local/cdf', enter the following... make INSTALLDIR=/usr/local/cdf install Note that `install' is at the end of the command line after the `make' variable.
