|
||||
# DESCRIPTION
|
||||
#
|
||||
# Try to find a compiler option that enables most reasonable warnings.
|
||||
# Specify compiler options that enable most reasonable warnings. For the
|
||||
# GNU Compiler Collection (GCC), for example, it will be "-Wall". The
|
||||
# result is added to shellvar, one of CFLAGS, CXXFLAGS or FCFLAGS if the
|
||||
# first parameter is not specified.
|
||||
#
|
||||
# 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.
|
||||
# Each of these macros accepts the following optional arguments:
|
||||
#
|
||||
# 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.
|
||||
# - $1 - shellvar
|
||||
# shell variable to use (CFLAGS, CXXFLAGS or FCFLAGS if not
|
||||
# specified, depending on macro)
|
||||
#
|
||||
# - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
|
||||
# - $2 add-value-if-not-found : nothing
|
||||
# - $3 action-if-found : add value to shellvariable
|
||||
# - $4 action-if-not-found : nothing
|
||||
# - $2 - default
|
||||
# value to use for flags if compiler vendor cannot be determined (by
|
||||
# default, "")
|
||||
#
|
||||
# NOTE: These macros depend on AX_APPEND_FLAG.
|
||||
# - $3 - action-if-found
|
||||
# action to take if the compiler vendor has been successfully
|
||||
# determined (by default, add the appropriate compiler flags to
|
||||
# shellvar)
|
||||
#
|
||||
# - $4 - action-if-not-found
|
||||
# action to take if the compiler vendor has not been determined or
|
||||
# is unknown (by default, add the default flags, or "" if not
|
||||
# specified, to shellvar)
|
||||
#
|
||||
# These macros use AX_COMPILER_VENDOR to determine which flags should be
|
||||
# returned for a given compiler. Not all compilers currently have flags
|
||||
# defined for them; patches are welcome. If need be, compiler flags may
|
||||
# be made language-dependent: use a construct like the following:
|
||||
#
|
||||
# [vendor_name], [m4_if(_AC_LANG_PREFIX,[C], VAR="--relevant-c-flags",dnl
|
||||
# m4_if(_AC_LANG_PREFIX,[CXX], VAR="--relevant-c++-flags",dnl
|
||||
# m4_if(_AC_LANG_PREFIX,[FC], VAR="--relevant-fortran-flags",dnl
|
||||
# VAR="$2"; FOUND="no")))],
|
||||
#
|
||||
# Note: These macros also depend on AX_PREPEND_FLAG.

dnl the for-argument contains a list of options. The first part of

dnl these does only exist to detect the compiler - usually it is

dnl a global option to enable -ansi or -extrawarnings. All other

dnl compilers will fail about it. That was needed since a lot of

dnl compilers will give false positives for some option-syntax
|

dnl like -Woption or -Xoption as they think of it is a pass-through
|

dnl to later compile stages or something. The "%" is used as a

dnl delimiter. A non-option comment can be given after "%%" marks
|
||||
dnl which will be shown but not added to the respective C/CXXFLAGS.

# DESCRIPTION
|
||||
#
|
||||
# Determine the vendor of the C/C++ compiler, e.g., gnu, intel, ibm, sun,
|
||||
# hp, borland, comeau, dec, cray, kai, lcc, metrowerks, sgi, microsoft,
|
||||
# watcom, etc. The vendor is returned in the cache variable
|
||||
# $ax_cv_c_compiler_vendor for C and $ax_cv_cxx_compiler_vendor for C++.
|
||||
# Determine the vendor of the C, C++ or Fortran compiler. The vendor is
|
||||
# returned in the cache variable $ax_cv_c_compiler_vendor for C,
|
||||
# $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for
|
||||
# (modern) Fortran. The value is one of "intel", "ibm", "pathscale",
|
||||
# "clang" (LLVM), "cray", "fujitsu", "sdcc", "sx", "nvhpc" (NVIDIA HPC
|
||||
# Compiler), "portland" (PGI), "gnu" (GCC), "sun" (Oracle Developer
|
||||
# Studio), "hp", "dec", "borland", "comeau", "kai", "lcc", "sgi",
|
||||
# "microsoft", "metrowerks", "watcom", "tcc" (Tiny CC) or "unknown" (if
|
||||
# the compiler cannot be determined).
|
||||
#
|
||||
# To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT
|
||||
# with an appropriate preprocessor-enabled extension. For example:
|
||||
#
|
||||
# AC_LANG_PUSH([Fortran])
|
||||
# AC_PROG_FC
|
||||
# AC_FC_PP_SRCEXT([F])
|
||||
# AX_COMPILER_VENDOR

||||
# AC_LANG_POP([Fortran])
