22 # LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],

24 # ----------------------------------------------------------
25 # David Shaw <dshaw@jabberwocky.com> May-09-2006
26 #
27 # Checks for libcurl. DEFAULT-ACTION is the string yes or no to
28 # specify whether to default to --with-libcurl or --without-libcurl.
29 # If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
30 # minimum version of libcurl to accept. Pass the version as a regular
31 # version number like 7.10.1. If not supplied, any version is
32 # accepted. ACTION-IF-YES is a list of shell commands to run if
33 # libcurl was successfully found and passed the various tests.
34 # ACTION-IF-NO is a list of shell commands that are run otherwise.
35 # Note that using --without-libcurl does run ACTION-IF-NO.
36 #
37 # This macro #defines HAVE_LIBCURL if a working libcurl setup is
38 # found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
39 # values. Other useful defines are LIBCURL_FEATURE_xxx where xxx are
40 # the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
41 # where yyy are the various protocols supported by libcurl. Both xxx
42 # and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
43 # the macro for the complete list of possible defines. Shell
44 # variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
45 # defined to 'yes' for those features and protocols that were found.
46 # Note that xxx and yyy keep the same capitalization as in the
47 # curl-config list (e.g. it's "HTTP" and not "http").
48 #
49 # Users may override the detected values by doing something like:
50 # LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
51 #
52 # For the sake of sanity, this macro assumes that any libcurl that is
53 # found is after version 7.7.2, the first version that included the
54 # curl-config script. Note that it is very important for people
55 # packaging binary versions of libcurl to include this script!
56 # Without curl-config, we can only guess what protocols are available,
57 # or use curl_version_info to figure it out at runtime.

496 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
497 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
498 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
499 #
500 # Of course, Automake must honor this variable whenever it calls a
501 # tool from the auxiliary directory. The problem is that $srcdir (and
502 # therefore $ac_aux_dir as well) can be either absolute or relative,
503 # depending on how configure is run. This is pretty annoying, since
504 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
505 # source directory, any form will work fine, but in subdirectories a
506 # relative path needs to be adjusted first.
507 #
508 # $ac_aux_dir/missing
509 # fails when called from a subdirectory if $ac_aux_dir is relative
510 # $top_srcdir/$ac_aux_dir/missing
511 # fails if $ac_aux_dir is absolute,
512 # fails when called from a subdirectory in a VPATH build with
513 # a relative $ac_aux_dir
514 #
515 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
516 # are both prefixed by $srcdir. In an in-source build this is usually
517 # harmless because $srcdir is `.', but things will broke when you
518 # start a VPATH build or use an absolute $srcdir.
519 #
520 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
521 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
522 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
523 # and then we would define $MISSING as
524 # MISSING="\${SHELL} $am_aux_dir/missing"
525 # This will work as long as MISSING is not called from configure, because
526 # unfortunately $(top_srcdir) has no meaning in configure.
527 # However there are other variables, like CC, which are often used in
528 # configure, and could therefore not use this "fixed" $ac_aux_dir.
529 #
530 # Another solution, used here, is to always expand $ac_aux_dir to an
531 # absolute PATH. The drawback is that using absolute paths prevent a
532 # configured tree to be moved without reconfiguration.
