## Name: detect_motif.sh - Get motif lib location, version and other info.
##
## Description: Artificial intelligence to figure out:
##
## + Where the motif headers/lib are located.
## + Whether lesstif is being used.
## + The version of motif being used.
## + The compile and link flags needed to build motif apps.
##
## Author: Ramiro Estrugo <ramiro@netscape.com>

##############################################################################
## This script looks in the space sepeared list of directories
## (MOTIF_SEARCH_PATH) for motif headers and libraries.
##
## The search path can be overrided by the user by setting:
##
## MOZILLA_MOTIF_SEARCH_PATH
##
## To a space delimeted list of directories to search for motif paths.
##
## For example, if you have many different versions of motif installed,
## and you want the current build to use headers in /foo/motif/include
## and libraries in /foo/motif/lib, then do this:
##
## export MOZILLA_MOTIF_SEARCH_PATH="/foo/motif"
##
## The script also generates and builds a program 'detect_motif-OBJECT_NAME'
## which prints out info on the motif detected on the system.
##
## This information is munged into useful strings that can be printed
## through the various command line flags decribed bellow. This script
## can be invoked from Makefiles or other scripts in order to set
## flags needed to build motif program.
##
## The 'detect_motif-OBJECT_NAME' program is generated/built only
## once and reused. Because of the OBJECT_NAME suffix, it will work on
## multiple platforms at the same time.
##
## The generated files can be wiped by the --cleanup flag.
##
##
## Command Line Flags Supported:
##
## -l | --is-lesstif: Print True/False if usign lesstif.
##
## -v | --print-version: Print XmVERSION.
## -r | --print-revision: Print XmREVISION.
## -u | --print-update-level: Print XmUPDATE_LEVEL.
## -s | --print-version-string: Print XmVERSION_STRING.
##
## -id | --print-include-dir: Print dir of motif includes.
## -sd | --print-static-dir: Print dir of motif static libs.
## -dd | --print-dynamic-dir: Print dir of motif dynamic libs.
##
## -sl | --print-static-lib: Print static lib.
## -dl | --print-dynamic-lib: Print dynamic lib.
##
## -if | --print-include-flags: Print cc flags needed to build motif apps.
## -sf | --print-static-flags: Print ld flags for linking statically.
## -df | --print-dynamic-flags: Print ld flags for linking dynamically.
## -dp | --print-dynamic-paths: Print ld paths for linking dynamically.
##
## -de | --dynamic-ext: Set extension used on dynamic libs.
## -se | --static-ext: Set extension used on static libs.
##
## -o | --set-object-name: Set object name for current system.
## -cc | --set-compiler: Set compiler for building test program.
##
## -xif | --set-x11-include-flags: Set X11 include flags.
##
## -xpm | --requires-xpm: Print {True,False} if we need libXpm.
##
## -c | --cleanup: Clean up any generated files.
##
##
## Look for motif headers in the following places:
##
DEFAULT_MOTIF_INCLUDE_SEARCH_PATH="\

/usr/local/include \
