Additional Definitions. 16# 17# As used herein, "this License" refers to version 3 of the GNU Lesser 18# General Public License, and the "GNU GPL" refers to version 3 of the GNU 19# General Public License. 20# 21# "The Library" refers to a covered work governed by this License, 22# other than an Application or a Combined Work as defined below. 23# 24# An "Application" is any work that makes use of an interface provided 25# by the Library, but which is not otherwise based on the Library. 26# Defining a subclass of a class defined by the Library is deemed a mode 27# of using an interface provided by the Library. 28# 29# A "Combined Work" is a work produced by combining or linking an 30# Application with the Library. The particular version of the Library 31# with which the Combined Work was made is also called the "Linked 32# Version". 33# 34# The "Minimal Corresponding Source" for a Combined Work means the 35# Corresponding Source for the Combined Work, excluding any source code 36# for portions of the Combined Work that, considered in isolation, are 37# based on the Application, and not on the Linked Version. 38# 39# The "Corresponding Application Code" for a Combined Work means the 40# object code and/or source code for the Application, including any data 41# and utility programs needed for reproducing the Combined Work from the 42# Application, but excluding the System Libraries of the Combined Work. 43# 44# 1. Exception to Section 3 of the GNU GPL. 45# 46# You may convey a covered work under sections 3 and 4 of this License 47# without being bound by section 3 of the GNU GPL. 48# 49# 2. Conveying Modified Versions. 50# 51# If you modify a copy of the Library, and, in your modifications, a 52# facility refers to a function or data to be supplied by an Application 53# that uses the facility (other than as an argument passed when the 54# facility is invoked), then you may convey a copy of the modified 55# version: 56# 57# a) under this License, provided that you make a good faith effort to 58# ensure that, in the event an Application does not supply the 59# function or data, the facility still operates, and performs 60# whatever part of its purpose remains meaningful, or 61# 62# b) under the GNU GPL, with none of the additional permissions of 63# this License applicable to that copy. 64# 65# 3. Object Code Incorporating Material from Library Header Files. 66# 67# The object code form of an Application may incorporate material from 68# a header file that is part of the Library. You may convey such object 69# code under terms of your choice, provided that, if the incorporated 70# material is not limited to numerical parameters, data structure 71# layouts and accessors, or small macros, inline functions and templates 72# (ten or fewer lines in length), you do both of the following: 73# 74# a) Give prominent notice with each copy of the object code that the 75# Library is used in it and that the Library and its use are 76# covered by this License. 77# 78# b) Accompany the object code with a copy of the GNU GPL and this license 79# document. 80# 81# 4. Combined Works. 82# 83# You may convey a Combined Work under terms of your choice that, 84# taken together, effectively do not restrict modification of the 85# portions of the Library contained in the Combined Work and reverse 86# engineering for debugging such modifications, if you also do each of 87# the following: 88# 89# a) Give prominent notice with each copy of the Combined Work that 90# the Library is used in it and that the Library and its use are 91# covered by this License. 92# 93# b) Accompany the Combined Work with a copy of the GNU GPL and this license 94# document. 95# 96# c) For a Combined Work that displays copyright notices during 97# execution, include the copyright notice for the Library among 98# these notices, as well as a reference directing the user to the 99# copies of the GNU GPL and this license document. 100# 101# d) Do one of the following: 102# 103# 0) Convey the Minimal Corresponding Source under the terms of this 104# License, and the Corresponding Application Code in a form 105# suitable for, and under terms that permit, the user to 106# recombine or relink the Application with a modified version of 107# the Linked Version to produce a modified Combined Work, in the 108# manner specified by section 6 of the GNU GPL for conveying 109# Corresponding Source. 110# 111# 1) Use a suitable shared library mechanism for linking with the 112# Library. A suitable mechanism is one that (a) uses at run time 113# a copy of the Library already present on the user's computer 114# system, and (b) will operate properly with a modified version 115# of the Library that is interface-compatible with the Linked 116# Version. 117# 118# e) Provide Installation Information, but only if you would otherwise 119# be required to provide such information under section 6 of the 120# GNU GPL, and only to the extent that such information is 121# necessary to install and execute a modified version of the 122# Combined Work produced by recombining or relinking the 123# Application with a modified version of the Linked Version. (If 124# you use option 4d0, the Installation Information must accompany 125# the Minimal Corresponding Source and Corresponding Application 126# Code. If you use option 4d1, you must provide the Installation 127# Information in the manner specified by section 6 of the GNU GPL 128# for conveying Corresponding Source.) 129# 130# 5. Combined Libraries. 131# 132# You may place library facilities that are a work based on the 133# Library side by side in a single library together with other library 134# facilities that are not Applications and are not covered by this 135# License, and convey such a combined library under terms of your 136# choice, if you do both of the following: 137# 138# a) Accompany the combined library with a copy of the same work based 139# on the Library, uncombined with any other library facilities, 140# conveyed under the terms of this License. 141# 142# b) Give prominent notice with the combined library that part of it 143# is a work based on the Library, and explaining where to find the 144# accompanying uncombined form of the same work. 145# 146# 6. Revised Versions of the GNU Lesser General Public License. 147# 148# The Free Software Foundation may publish revised and/or new versions 149# of the GNU Lesser General Public License from time to time. Such new 150# versions will be similar in spirit to the present version, but may 151# differ in detail to address new problems or concerns. 152# 153# Each version is given a distinguishing version number. If the 154# Library as you received it specifies that a certain numbered version 155# of the GNU Lesser General Public License "or any later version" 156# applies to it, you have the option of following the terms and 157# conditions either of that published version or of any later version 158# published by the Free Software Foundation. If the Library as you 159# received it does not specify a version number of the GNU Lesser 160# General Public License, you may choose any version of the GNU Lesser 161# General Public License ever published by the Free Software Foundation. 162# 163# If the Library as you received it specifies that a proxy can decide 164# whether future versions of the GNU Lesser General Public License shall 165# apply, that proxy's public statement of acceptance of any version is 166# permanent authorization for you to choose that version for the 167# Library. 168 169# AC_CHECK_FRAMEWORK(FRAMEWORK, FUNCTION, 170# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND], 171# [OTHER-LIBRARIES]) 172# ------------------------------------------------------ 173# 174# Use a cache variable name containing both the framework and function name, 175# because the test really is for framework $1 defining function $2, not 176# just for framework $1. Separate tests with the same $1 and different $2s 177# may have different results. 178# 179# Note that using directly AS_VAR_PUSHDEF([ac_Framework], [ac_cv_framework_$1_$2]) 180# is asking for troubles, since AC_CHECK_FRAMEWORK($framework, fun) would give 181# ac_cv_framework_$framework_fun, which is definitely not what was meant. Hence 182# the AS_LITERAL_IF indirection. 183# 184# FIXME: This macro is extremely suspicious. It DEFINEs unconditionally, 185# whatever the FUNCTION, in addition to not being a *S macro. Note 186# that the cache does depend upon the function we are looking for. 187# 188# It is on purpose we used `ac_check_framework_save_LIBS' and not just 189# `ac_save_LIBS': there are many macros which don't want to see `LIBS' 190# changed but still want to use AC_CHECK_FRAMEWORK, so they save `LIBS'. 191# And ``ac_save_LIBS' is too tempting a name, so let's leave them some 192# freedom. 193AC_DEFUN([AC_CHECK_FRAMEWORK], 194[m4_ifval([$3], , [AH_CHECK_FRAMEWORK([$1])])dnl 195AS_LITERAL_IF([$1], 196 [AS_VAR_PUSHDEF([ac_Framework], [ac_cv_framework_$1_$2])], 197 [AS_VAR_PUSHDEF([ac_Framework], [ac_cv_framework_$1''_$2])])dnl 198AC_CACHE_CHECK([for $2 in $1 framework], ac_Framework, 199[ac_check_framework_save_LIBS=$LIBS 200LIBS="-framework $1 $5 $LIBS" 201AC_LINK_IFELSE([AC_LANG_CALL([], [$2])], 202 [AS_VAR_SET(ac_Framework, yes)], 203 [AS_VAR_SET(ac_Framework, no)]) 204LIBS=$ac_check_framework_save_LIBS]) 205AS_IF([test AS_VAR_GET(ac_Framework) = yes], 206 [m4_default([$3], [AC_DEFINE_UNQUOTED(AS_TR_CPP(HAVE_FRAMEWORK_$1)) 207 LIBS="-framework $1 $LIBS" 208])], 209 [$4])dnl 210AS_VAR_POPDEF([ac_Framework])dnl 211])# AC_CHECK_FRAMEWORK 212 213# AH_CHECK_FRAMEWORK(FRAMEWORK) 214# --------------------- 215m4_define([AH_CHECK_FRAMEWORK], 216[AH_TEMPLATE(AS_TR_CPP(HAVE_FRAMEWORK_$1), 217 [Define to 1 if you have the `]$1[' framework (-framework ]$1[).])]) 218
