Example: setting prefix and exec-prefix

Use `--prefix' and `--exec-prefix' to explicitly set installation directories. These variables are set to subdirectories of `/usr/cygnus/progressive-date' by default (see section Building with the defaults). For more involved discussion on the nuances of these options, see section The Heterogeneous Updateable Toolkit. For discussion on the options themselves, see section Options to configure.

This example shows different installation directories from the default. The defaults for this example are as follows (the release is shown as `94q4'):

prefix       set on command line
exec-prefix  set on command line
target       nonexistent by default; cross example shows `m68k-coff'
srcdir       current directory; example shows `/usr/local/src'
objdir       same as srcdir
release      shown on distribution tape (example uses `94q4')

The native and cross examples show a complete walk-through for each type of build. (The only difference is the use of the `--target' option to configure for a cross-development toolkit. We'll use `m68k-coff' as an example for building a cross-development toolkit.)

For this example, we'll set the configuration to install host-independent files (documentation, library source code) in `/usr/local', and host-dependent files (binary programs, precompiled libraries) in `/usr/local/H-sun4'. The programs are to be accessible after installation via the symbolic link `/usr/progressive' (see section The Heterogeneous Updateable Toolkit). Builds are shown independently; for an example of a simultaneous build, see section Multiple simultaneous builds.

In either of the above examples, you must set your PATH to include `/usr/progressive/bin' in order to access the tools easily.
