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.
