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.
58
59 If multiple builds of wxWidgets are available, you can use the options
60 --prefix, --host, --toolkit, --unicode, --debug, --static, --universal and
61 --version to select from them. The --selected-config option shows the name
62 of the current configuration and --list shows available alternatives which
63 match specified criteria. The --utility option returns the correct version
64 of UTIL to use with the selected build. The --linkdeps option returns only
65 static libraries for your makefile link rule dependencies.
66
67 The LIBS arguments (comma or space separated) may be used to specify the
68 wxWidgets libraries that you wish to use. The "std" label may be used to
69 import all libraries that would be used by default if none were specified
70 explicitly, e.g. wx-config --libs core,base. The "all" label may be used
71 to import all libraries that have been compiled which are shown in the
72 list below. The --optional-libs parameter should be followed by a list
73 of libs that should be linked to, but only if they are available.
74
75 Available libraries in this build are : @BUILT_WX_LIBS@

427 # From here on, we'll need to be able to figure out a delegation target.
428 # -----------------------------------------------------------------------
429
430 # The rules for delegation are:
431 #
432 # 1. If the specification is so general that it matches the default config
433 # (ie. this one on a first pass), then the default config will be used
434 # even if other installed libs would also match the spec.
435 #
436 # 2. If the default config does not match, find a list of all installed
437 # libraries that do match.
438 # a. If that list is empty, the specification is incompatible
439 # with any installed lib. Warn and abort.
440 # b. If that list contains exactly one candidate. Delegate to
441 # that candidate.
442 # c. If the list contains multiple candidates, pass on to step 3.
443 #
444 # 3. Attempt to discriminate among rival candidates by their similarity
445 # to the default configuration (ie. this one). If we can find a unique
446 # candidate in this way, delegate to it. If not, present a list of
447 # options to the user and request that they disambiguate it with one or
448 # more additional fields.
449 #
450 # To refine the specified pattern, we specialise each unbound field
451 # using the default value from this config file. If that results in
452 # no matches, we unbind it again and try the next field. If it still
453 # results in multiple matches we try binding the next field as well
454 # until a unique or null result again occurs.
455 #
456 # A more general way to look at this, is the feature specifiers are all
457 # modifiers of the wx-config you are calling. If you supply none, the
458 # default for that build configuration will be used. If you supply one
459 # or more that the default build cannot satisfy, it will try to find the
460 # config most like itself with the desired feature(s) enabled.
461 # The features configured into the first wx-config called will be taken
462 # as implicitly specified if it is necessary to disambiguate likely
463 # candidates from the information that was explicitly provided.

500 # partial ordering it should find the first match with the most significant
501 # similarity to this file that unambiguously meets the user specification.
502 # If such a match exists it will be output to stdout.

1243 # each platform has only one definition of 'resource', compiled
1244 # or not, and so we can abstract that neatly to return a platform
1245 # specific invocation of the appropriate tool. The bad news is,
1246 # windres (at least) requires knowledge of the wx header files
1247 # location(s) that cannot be predicted reliably before the call to
1248 # wx-config is made. Currently for all known resource compilers,
1249 # we can simply return a command and some salient configuration
1250 # options in response to a request for --rescomp. So here we
1251 # top up the options for any tools that may require information
1252 # that was only just determined in the last few machine cycles,
1253 # then output the necessary incantation for the platform.

1256 # has run. Do not add anything here that is already known there.
