## Name: detect_x11.sh - Get X11 lib location, version and other info.
##
## Description: Artificial intelligence to figure out:
##
## + Where the X11 headers/lib are located.
## + The version of X11 being used.
## + The compile and link flags needed to build X11 apps.
##
## Author: Ramiro Estrugo <ramiro@netscape.com>
##
##############################################################################
## This script looks in the space sepeared list of directories
## (X11_SEARCH_PATH) for x11 headers and libraries.
##
## The search path can be overrided by the user by setting:
##
## MOZILLA_X11_SEARCH_PATH
##
## To a space delimeted list of directories to search for x11 paths.
##
## For example, if you have many different versions of x11 installed,
## and you want the current build to use headers in /foo/x11/include
## and libraries in /foo/x11/lib, then do this:
##
## export MOZILLA_X11_SEARCH_PATH="/foo/x11"
##
## The script also generates and builds a program 'detect_x11-OBJECT_NAME'
## which prints out info on the x11 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 x11 program.
##
## The get 'detect_x11-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:
##
## -v | --print-version: Print XlibSpecificationRelease.
## -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 x11 includes.
## -sd | --print-static-dir: Print dir of x11 static libs.
## -dd | --print-dynamic-dir: Print dir of x11 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 x11 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.
##
## -c | --cleanup: Clean up any generated files.
##
##
## Look for x11 stuff in the following places:
##
DEFAULT_X11_SEARCH_PATH="\
/usr/local \
/usr/openwin \
/usr/X11R6 \
/usr \
"
##
## The user can override the default share path by setting MOZILLA_X11_SEARCH
##
if [ -n "$MOZILLA_X11_SEARCH_PATH" ]
then
X11_SEARCH_PATH=$MOZILLA_X11_SEARCH_PATH
