10 # Essentially a fresh start this time around, but for maximum
11 # compatibility basic code was taken from, and heavy reference
12 # made to, the previously unattributed wx-config from cvs.
13 # All the usual suspects contributed to the dicussion that led
14 # to this new work and likewise to the ideas and content in the
15 # original (which was probably influenced by gtk), among them:

54 wx-config returns information about the wxWidgets libraries available on
55 your system. It may be used to retrieve the information required to build
56 applications using these libraries using --cppflags, --cxxflags, --cflags,
57 and --libs options. And you may query the properties of this configuration
58 using --query-{host,toolkit,widgetset,chartype,debugtype,version,linkage}.
59
60 If multiple builds of wxWidgets are available, you can use the options
61 --prefix, --host, --toolkit, --unicode, --debug, --static, --universal and
62 --version to select from them. The --selected-config option shows the name
63 of the current configuration and --list shows available alternatives which
64 match specified criteria. The --utility option returns the correct version
65 of UTIL to use with the selected build. The --linkdeps option returns only
66 static libraries for your makefile link rule dependencies.
67
68 The LIBS arguments (comma or space separated) may be used to specify the
69 wxWidgets libraries that you wish to use. The "std" label may be used to
70 import all libraries that would be used by default if none were specified
71 explicitly, e.g. wx-config --libs core,base. The "all" label may be used
72 to import all libraries that have been compiled which are shown in the
73 list below. The --optional-libs parameter should be followed by a list
74 of libs that should be linked to, but only if they are available.

434 # From here on, we'll need to be able to figure out a delegation target.
435 # -----------------------------------------------------------------------
436
437 # The rules for delegation are:
438 #
439 # 1. If the specification is so general that it matches the default config
440 # (ie. this one on a first pass), then the default config will be used
441 # even if other installed libs would also match the spec.
442 #
443 # 2. If the default config does not match, find a list of all installed
444 # libraries that do match.
445 # a. If that list is empty, the specification is incompatible
446 # with any installed lib. Warn and abort.
447 # b. If that list contains exactly one candidate. Delegate to
448 # that candidate.
449 # c. If the list contains multiple candidates, pass on to step 3.
450 #
451 # 3. Attempt to discriminate among rival candidates by their similarity
452 # to the default configuration (ie. this one). If we can find a unique
453 # candidate in this way, delegate to it. If not, present a list of
454 # options to the user and request that they disambiguate it with one or
455 # more additional fields.
456 #
457 # To refine the specified pattern, we specialise each unbound field
458 # using the default value from this config file. If that results in
459 # no matches, we unbind it again and try the next field. If it still
460 # results in multiple matches we try binding the next field as well
461 # until a unique or null result again occurs.
462 #
463 # A more general way to look at this, is the feature specifiers are all
464 # modifiers of the wx-config you are calling. If you supply none, the
465 # default for that build configuration will be used. If you supply one
466 # or more that the default build cannot satisfy, it will try to find the
467 # config most like itself with the desired feature(s) enabled.
468 # The features configured into the first wx-config called will be taken
469 # as implicitly specified if it is necessary to disambiguate likely
470 # candidates from the information that was explicitly provided.

1256 # each platform has only one definition of 'resource', compiled
1257 # or not, and so we can abstract that neatly to return a platform
1258 # specific invocation of the appropriate tool. The bad news is,
1259 # windres (at least) requires knowledge of the wx header files
1260 # location(s) that cannot be predicted reliably before the call to
1261 # wx-config is made. Currently for all known resource compilers,
1262 # we can simply return a command and some salient configuration
1263 # options in response to a request for --rescomp. So here we
1264 # top up the options for any tools that may require information
1265 # that was only just determined in the last few machine cycles,
1266 # then output the necessary incantation for the platform.

1269 # has run. Do not add anything here that is already known there.
