# 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. |
