| # 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. |
