# SYNOPSIS |
|||
# |
|||
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional]) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# Check for baseline language coverage in the compiler for the specified |
|||
# version of the C++ standard. If necessary, add switches to CXX and |
|||
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard) |
|||
# or '14' (for the C++14 standard). |
|||
# |
|||
# The second argument, if specified, indicates whether you insist on an |
|||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. |
|||
# -std=c++11). If neither is specified, you get whatever works, with |
|||
# preference for no added switch, and then for an extended mode. |
|||
# |
|||
# The third argument, if specified 'mandatory' or if left unspecified, |
|||
# indicates that baseline support for the specified C++ standard is |
|||
# required and that the macro should error out if no mode with that |
|||
# support is found. If specified 'optional', then configuration proceeds |
|||
# regardless, after defining HAVE_CXX${VERSION} if and only if a |
|||
# supporting mode is found. |

# SYNOPSIS |

# AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional]) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# Check for baseline language coverage in the compiler for the C++11 |
|||
# standard; if necessary, add switches to CXXFLAGS to enable support. |
|||
# |
|||
# The first argument, if specified, indicates whether you insist on an |
|||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. |
|||
# -std=c++11). If neither is specified, you get whatever works, with |
|||
# preference for an extended mode. |
|||
# |
|||
# The second argument, if specified 'mandatory' or if left unspecified, |
|||
# indicates that baseline C++11 support is required and that the macro |
|||
# should error out if no mode with that support is found. If specified |
|||
# 'optional', then configuration proceeds regardless, after defining |
|||
# HAVE_CXX11 if and only if a supporting mode is found. |

# 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. |
