# efl_find.x.m4 - Macros to locate X11. -*- Autoconf -*-

# EFL_FIND_X(VARIABLE-PREFIX, [headers = "X11/Xlib.h"],
|
|
# [libs-and-functions = "X11 XOpenDisplay"],
|
|
# [action-if-found], [action-if-not-found])
|
|
# checks for X11 using, in order:
|
|
# 1) Xorg pkg-config files (using enviroment variables EFL_X11_CFLAGS
|
|
# and EFL_X11_LIBS if set, but only if x11.pc exists)
|
|
# 2) command line options: --x-includes=dir, --x-libraries=dir
|
|
# assume there is an X11 in the given directories
|
|
# 3) XMKMF environment variable if set
|
|
# 4) xmkmf executable if found
|
|
# 5) list of "standard" directories
|
|
#
|
|
# 2-5 is handled by A_PATH_X
|
|
#
|
|
# If a X11 is found, [action-if-success] is run and VARIABLE_cflags and
|
|
# VARIABLE_libs and VARIABLE_libdirs are defined and substituted.
|
|
# VARIABLE_libs will contain all of the libs listed in libs-and-functions.
|
|
# VARIABLE_libdirs will contain all -Lpath:s found in VARIABLE_libs
|
|
#
|
|
# headers is a list of headers to look for. libs-and-functions is a list of
|
|
# library and function pairs to look for.
|
|
# Each lib and function is checked in pairs, example:
|
|
# EFL_FIND_X([EVAS_X11], [X11/X.h], [X11 XCreateImage Xext XShmCreateImage])
|
|
# will look for XCreateImage in X11 and XShmCreateImage in Xext and include
|
|
# both -lX11 and -lXext in VARIABLE_libs
|
|
#
|
|
# action-if-found is only called if X11, all headers, all libraries and
|
|
# all functions are found.
|
|
# You can call EFL_FIND_X multiple times with different lists of headers, libs
|
|
# and functions.
