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