22 | # LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION], | ||
23 | # [ACTION-IF-YES], [ACTION-IF-NO]) | ||
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. | ||
