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