# This file is part of the HDF5 build script. It is processed shortly

#----------------------------------------------------------------------------
# Compiler flags. The CPPFLAGS values should not include package debug
# flags like `-DH5G_DEBUG' since these are added with the
# `--enable-debug' switch of configure.
#----------------------------------------------------------------------------
# Choosing a C Compiler
# ---------------------
#
# The user should be able to specify the compiler by setting the CC
# environment variable to the name of the compiler and any switches it
# requires for proper operation. If CC is unset then this script may
# set it. If CC is unset by time this script completes then configure
# will try `gcc' and `cc' in that order (perhaps some others too).
#
# Note: Code later in this file may depend on the value of $CC_BASENAME
# in order to distinguish between different compilers when
# deciding which compiler command-line switches to use. This
# variable is set based on the incoming value of $CC and is only
# used within this file.

# C Compiler and Preprocessor Flags
# ---------------------------------
#
# Flags that end with `_CFLAGS' are always passed to the compiler.
# Flags that end with `_CPPFLAGS' are passed to the compiler when
# compiling but not when linking.
#
# DEBUG_CFLAGS Flags to pass to the compiler to create a
# DEBUG_CPPFLAGS library suitable for use with debugging
# tools. Usually this list will exclude
# optimization switches (like `-O') and include
# switches that turn on symbolic debugging
# support (like `-g').
#
# PROD_CFLAGS Flags to pass to the compiler to create a
# PROD_CPPFLAGS production version of the library. These
# usually exclude symbolic debugging switches
# (like `-g') and include optimization switches
# (like `-O').
#
# PROFILE_CFLAGS Flags to pass to the compiler to create a
# PROFILE_CPPFLAGS library suitable for performance testing (like
# `-pg'). This may or may not include debugging
# or production flags.
#
# H5_CFLAGS Flags can be added to this variable which
# might already be partially initialized. These
# flags will always be passed to the compiler
# and should include switches to turn on full
# warnings. HDF5 attempts to be ANSI and Posix
# compliant and employ good programming
# practices resulting in few if any
# warnings.
#
# Warning flags do not have to be added to H5_CFLAGS
# variable if the compiler is the GNU gcc
# compiler or a descendent of gcc such as EGCS or PGCC.
#
# AM_CFLAGS Flags added directly into this variable will
# be propagated to the compiler wrapper scripts (h5cc,
# h5c++, et cetera) in addition to being used to compile
# the library.
#
# These flags should be set according to the compiler being used.
# There are two ways to check the compiler. You can try using `-v' or
# `--version' to see if the compiler will print a version string. You
# can use the value of $CC_BASENAME which is the base name of the
# first word in $CC (note that the value of CC may have changed
# above).
