A.2.1 Installing the OPeNDAP Libraries

In order to link and run client programs, the only OPeNDAP software that must be installed are the OPeNDAP libraries. The following libraries, described in Section 3.1 must be installed in the /usr/lib directory, or somewhere else where the linker will find them. Simply copy them into that directory from the OPeNDAP distribution.

• libdap++.a
• The OPeNDAP version of the API your software uses.

In addition to the OPeNDAP libraries, the following software is also required to link an OPeNDAP client. You can obtain them from the OPeNDAP Home page or OPeNDAP ftp site. (Look under your machine type, then under DODS/packages/lib.) The first two libraries should be part of the Tcl/Tk distribution. The other three libraries are GNU software.

• libtcl.a
• libexpect.a
• libstdc++.a
• librx.a (Regular expression software. Part of the regex package.)
• libz.a (Compression software. Part of the gzip distribution.)

To run an OPeNDAP client, you should have the wish and gzip programs in the PATH, and the following Tcl programs must be either in the DODS_ROOT/etc directory:

• dod_gui.tcl
• progress.tcl
• error.tcl

An OPeNDAP client will still execute without these programs, but important functionality, including the GUI manager and the data compression will be absent. Refer to the INSTALL file included in each distribution for specific information about setting up the client.
