# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],

# 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.
