# http://svn.saurik.com/repos/cycript/trunk/framework.m4 # # GNU LESSER GENERAL PUBLIC LICENSE # Version 3, 29 June 2007 # # Copyright (C) 2007 Free Software Foundation, Inc. # Everyone is permitted to copy and distribute verbatim copies # of this license document, but changing it is not allowed. # # # This version of the GNU Lesser General Public License incorporates # the terms and conditions of version 3 of the GNU General Public # License, supplemented by the additional permissions listed below. # # 0. Additional Definitions. # # As used herein, "this License" refers to version 3 of the GNU Lesser # General Public License, and the "GNU GPL" refers to version 3 of the GNU # General Public License. # # "The Library" refers to a covered work governed by this License, # other than an Application or a Combined Work as defined below. # # An "Application" is any work that makes use of an interface provided # by the Library, but which is not otherwise based on the Library. # Defining a subclass of a class defined by the Library is deemed a mode # of using an interface provided by the Library. # # A "Combined Work" is a work produced by combining or linking an # Application with the Library. The particular version of the Library # with which the Combined Work was made is also called the "Linked # Version". # # The "Minimal Corresponding Source" for a Combined Work means the # Corresponding Source for the Combined Work, excluding any source code # for portions of the Combined Work that, considered in isolation, are # based on the Application, and not on the Linked Version. # # The "Corresponding Application Code" for a Combined Work means the # object code and/or source code for the Application, including any data # and utility programs needed for reproducing the Combined Work from the # Application, but excluding the System Libraries of the Combined Work. # # 1. Exception to Section 3 of the GNU GPL. # # You may convey a covered work under sections 3 and 4 of this License # without being bound by section 3 of the GNU GPL. # # 2. Conveying Modified Versions. # # If you modify a copy of the Library, and, in your modifications, a # facility refers to a function or data to be supplied by an Application # that uses the facility (other than as an argument passed when the # facility is invoked), then you may convey a copy of the modified # version: # # a) under this License, provided that you make a good faith effort to # ensure that, in the event an Application does not supply the # function or data, the facility still operates, and performs # whatever part of its purpose remains meaningful, or # # b) under the GNU GPL, with none of the additional permissions of # this License applicable to that copy. # # 3. Object Code Incorporating Material from Library Header Files. # # The object code form of an Application may incorporate material from # a header file that is part of the Library. You may convey such object # code under terms of your choice, provided that, if the incorporated # material is not limited to numerical parameters, data structure # layouts and accessors, or small macros, inline functions and templates # (ten or fewer lines in length), you do both of the following: # # a) Give prominent notice with each copy of the object code that the # Library is used in it and that the Library and its use are # covered by this License. # # b) Accompany the object code with a copy of the GNU GPL and this license # document. # # 4. Combined Works. # # You may convey a Combined Work under terms of your choice that, # taken together, effectively do not restrict modification of the # portions of the Library contained in the Combined Work and reverse # engineering for debugging such modifications, if you also do each of # the following: # # a) Give prominent notice with each copy of the Combined Work that # the Library is used in it and that the Library and its use are # covered by this License. # # b) Accompany the Combined Work with a copy of the GNU GPL and this license # document. # # c) For a Combined Work that displays copyright notices during # execution, include the copyright notice for the Library among # these notices, as well as a reference directing the user to the # copies of the GNU GPL and this license document. # # d) Do one of the following: # # 0) Convey the Minimal Corresponding Source under the terms of this # License, and the Corresponding Application Code in a form # suitable for, and under terms that permit, the user to # recombine or relink the Application with a modified version of # the Linked Version to produce a modified Combined Work, in the # manner specified by section 6 of the GNU GPL for conveying # Corresponding Source. # # 1) Use a suitable shared library mechanism for linking with the # Library. A suitable mechanism is one that (a) uses at run time # a copy of the Library already present on the user's computer # system, and (b) will operate properly with a modified version # of the Library that is interface-compatible with the Linked # Version. # # e) Provide Installation Information, but only if you would otherwise # be required to provide such information under section 6 of the # GNU GPL, and only to the extent that such information is # necessary to install and execute a modified version of the # Combined Work produced by recombining or relinking the # Application with a modified version of the Linked Version. (If # you use option 4d0, the Installation Information must accompany # the Minimal Corresponding Source and Corresponding Application # Code. If you use option 4d1, you must provide the Installation # Information in the manner specified by section 6 of the GNU GPL # for conveying Corresponding Source.) # # 5. Combined Libraries. # # You may place library facilities that are a work based on the # Library side by side in a single library together with other library # facilities that are not Applications and are not covered by this # License, and convey such a combined library under terms of your # choice, if you do both of the following: # # a) Accompany the combined library with a copy of the same work based # on the Library, uncombined with any other library facilities, # conveyed under the terms of this License. # # b) Give prominent notice with the combined library that part of it # is a work based on the Library, and explaining where to find the # accompanying uncombined form of the same work. # # 6. Revised Versions of the GNU Lesser General Public License. # # The Free Software Foundation may publish revised and/or new versions # of the GNU Lesser General Public License from time to time. Such new # versions will be similar in spirit to the present version, but may # differ in detail to address new problems or concerns. # # Each version is given a distinguishing version number. If the # Library as you received it specifies that a certain numbered version # of the GNU Lesser General Public License "or any later version" # applies to it, you have the option of following the terms and # conditions either of that published version or of any later version # published by the Free Software Foundation. If the Library as you # received it does not specify a version number of the GNU Lesser # General Public License, you may choose any version of the GNU Lesser # General Public License ever published by the Free Software Foundation. # # If the Library as you received it specifies that a proxy can decide # whether future versions of the GNU Lesser General Public License shall # apply, that proxy's public statement of acceptance of any version is # permanent authorization for you to choose that version for the # Library. # AC_CHECK_FRAMEWORK(FRAMEWORK, FUNCTION, # [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND], # [OTHER-LIBRARIES]) # ------------------------------------------------------ # # Use a cache variable name containing both the framework and function name, # because the test really is for framework $1 defining function $2, not # just for framework $1. Separate tests with the same $1 and different $2s # may have different results. # # Note that using directly AS_VAR_PUSHDEF([ac_Framework], [ac_cv_framework_$1_$2]) # is asking for troubles, since AC_CHECK_FRAMEWORK($framework, fun) would give # ac_cv_framework_$framework_fun, which is definitely not what was meant. Hence # the AS_LITERAL_IF indirection. # # FIXME: This macro is extremely suspicious. It DEFINEs unconditionally, # whatever the FUNCTION, in addition to not being a *S macro. Note # that the cache does depend upon the function we are looking for. # # It is on purpose we used `ac_check_framework_save_LIBS' and not just # `ac_save_LIBS': there are many macros which don't want to see `LIBS' # changed but still want to use AC_CHECK_FRAMEWORK, so they save `LIBS'. # And ``ac_save_LIBS' is too tempting a name, so let's leave them some # freedom.
