# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
|
|
||||||
#
|
|
||||||
# DESCRIPTION
|
|
||||||
#
|
|
||||||
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
|
|
||||||
# added in between.
|
|
||||||
#
|
|
||||||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
|
|
||||||
# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
|
|
||||||
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
|
|
||||||
# FLAG.
|
|
||||||
#

# AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
|
|
||||||
#
|
|
||||||
# DESCRIPTION
|
|
||||||
#
|
|
||||||
# For every FLAG1, FLAG2 it is checked whether the linker works with the
|
|
||||||
# flag. If it does, the flag is added FLAGS-VARIABLE
|
|
||||||
#
|
|
||||||
# If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is
|
|
||||||
# used. During the check the flag is always added to the linker's flags.
|
|
||||||
#
|
|
||||||
# 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: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG.
|
|
||||||
# Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS.

# DESCRIPTION
|
|
||||||
#
|
|
||||||
# Try to find a compiler option that enables most reasonable warnings.
|
|
||||||
#
|
|
||||||
# For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
|
|
||||||
# is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
|
|
||||||
#
|
|
||||||
# Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
|
|
||||||
# HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
|
|
||||||
# Intel compilers. For a given compiler, the Fortran flags are much more
|
|
||||||
# experimental than their C equivalents.

# AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
|
||||||
#
|
|
||||||
# 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.
|
|
||||||
#
|
|
||||||
# INPUT gives an alternative input source to AC_LINK_IFELSE.
|
|
||||||
#
|
|
||||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
|
||||||
# macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.

# 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 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 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.
