they are difficult to keep in sync so we will assume the developer has installed a copy locally.

# SYNOPSIS
|
||||
#
|
||||
# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# For every FLAG1, FLAG2 it is checked whether the compiler works with the
|
||||
# flag. If it does, the flag is added FLAGS-VARIABLE
|
||||
#
|
||||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
|
||||
# CFLAGS) is used. During the check the flag is always added to the
|
||||
# current language's flags.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
||||
# force the compiler to issue an error when a bad flag is given.
|
||||
#
|
||||
# NOTE: This macro depends on the AX_APPEND_FLAG and
|
||||
# AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
|
||||
# AX_APPEND_LINK_FLAGS.

# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
|

#
|

# DESCRIPTION
|

#
|

# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space

# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly

# FLAG.

# SYNOPSIS

# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's compiler
|
||||
# or gives an error. (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
||||
# force the compiler to issue an error when a bad flag is given.
|
||||
#

# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the linker or gives an error.
|
||||
# (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the linker's default flags
|
||||
# when the check is done. The check is thus made with the flags: "LDFLAGS
|
||||
# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
|
||||
# issue an error when a bad flag is given.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.

#

# DESCRIPTION
|

#
|

# Check for baseline language coverage in the compiler for the C++11

# standard; if necessary, add switches to CXXFLAGS to enable support.
|

# Errors out if no mode that supports C++11 baseline syntax can be found.
|
||||
# The 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.
