22# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
23# [ACTION-IF-YES], [ACTION-IF-NO])
24# ----------------------------------------------------------
25# David Shaw <dshaw@jabberwocky.com> May-09-2006
26#
27# Checks for libcurl. DEFAULT-ACTION is the string yes or no to
28# specify whether to default to --with-libcurl or --without-libcurl.
29# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
30# minimum version of libcurl to accept. Pass the version as a regular
31# version number like 7.10.1. If not supplied, any version is
32# accepted. ACTION-IF-YES is a list of shell commands to run if
33# libcurl was successfully found and passed the various tests.
34# ACTION-IF-NO is a list of shell commands that are run otherwise.
35# Note that using --without-libcurl does run ACTION-IF-NO.
36#
37# This macro #defines HAVE_LIBCURL if a working libcurl setup is
38# found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
39# values. Other useful defines are LIBCURL_FEATURE_xxx where xxx are
40# the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
41# where yyy are the various protocols supported by libcurl. Both xxx
42# and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
43# the macro for the complete list of possible defines. Shell
44# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
45# defined to 'yes' for those features and protocols that were found.
46# Note that xxx and yyy keep the same capitalization as in the
47# curl-config list (e.g. it's "HTTP" and not "http").
48#
49# Users may override the detected values by doing something like:
50# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
51#
52# For the sake of sanity, this macro assumes that any libcurl that is
53# found is after version 7.7.2, the first version that included the
54# curl-config script. Note that it is very important for people
55# packaging binary versions of libcurl to include this script!
56# Without curl-config, we can only guess what protocols are available,
57# or use curl_version_info to figure it out at runtime.
