+# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION], | |
+# [ACTION-IF-YES], [ACTION-IF-NO]) | |
+# ---------------------------------------------------------- | |
+# David Shaw <[email protected]> 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. | |
