AC_INIT([wxWidgets], [2.5.2], [wx-dev@lists.wxwidgets.org])

dnl the file passed to AC_CONFIG_SRCDIR should be specific to our package
AC_CONFIG_SRCDIR([wx-config.in])

dnl sets build, host, target variables and the same with _alias

dnl When making releases do:
dnl
dnl WX_RELEASE_NUMBER += 1
dnl
dnl ..and update WX_CURRENT, WX_RELEASE and WX_AGE according to the
dnl following rules:
dnl
dnl    If any changes have been made to the public interface, that is if any
dnl    exported class, method, global or global type has been added, removed
dnl    or changed in any way, then do:  WX_CURRENT += 1
dnl
dnl    If source changes have been made that *do not* alter the public
dnl    interface then do:  WX_REVISION += 1
dnl    If WX_CURRENT was incremented (as above) instead do:  WX_REVISION = 0
dnl
dnl    If any public interface was added, do:  WX_AGE += 1
dnl    If any public interface was removed (or altered in a way effectively
dnl    removing the previous definition), instead do:  WX_AGE = 0
dnl
dnl When the major or minor version numbers are incremented, all the above
dnl variables should be reset to 0.
dnl
dnl The resulting library name will be of the form:
dnl   libwx_$(TOOLKIT)-$(WX_RELEASE).so.$(WX_CURRENT).$(WX_REVISION).$(WX_AGE)

dnl Only add the -lm library if floating point functions cannot be used
dnl without it.  This check is important on cygwin because of the bizarre
dnl way that they have organized functions into libraries.  On cygwin, both
dnl libc.a and libm.a are symbolic links to a single lib libcygwin.a.  This
dnl means that
dnl   1) linking with -lm is not necessary, and
dnl   2) linking with -lm is dangerous if the order of libraries is wrong
dnl In particular, if you compile any program with -mno-cygwin and link with
dnl -lm, it will crash instantly when it is run.  This happens because the
dnl linker incorrectly links the Cygwin libm.a (==libcygwin.a), which replaces
dnl the ___main function instead of allowing it to be defined by
dnl /usr/lib/mingw/libmingw32.a as it should be.
dnl
dnl On MacOS X, this test will find that -lm is unnecessary and leave it out.
dnl
dnl Just check a few floating point functions. If they are all found without
dnl -lm, then we must not need -lm.
