/*
|
|
* XXX - this takes the plugin directory as an argument, because
|
|
* libethereal now has its own configure script and "config.h" file,
|
|
* which is what code in the "epan" directory includes, but we need
|
|
* to define PLUGIN_DIR in the top-level directory, as it's used by,
|
|
* for example, the Makefile for the Gryphon plugin, so it knows
|
|
* where to install the plugin.
|
|
*
|
|
* Eventually, we should probably have an "epan-configure" script
|
|
* (or "libethereal-configure", or whatever), along the lines of what
|
|
* GTK+ and GLib have, that can print, among other things, the directory
|
|
* into which plugins should be installed. That way, only libethereal
|
|
* need know what directory that is; programs using it won't, *and*
|
|
* Makefiles for plugins can just use "epan-configure" to figure out
|
|
* where to install the plugins.
|
|
*
|
|
* (Would that *more* libraries had configure scripts like that, so
|
|
* that configure scripts didn't have to go through various contortions
|
|
* to figure out where the header files and libraries for various
|
|
* libraries are located.)
