It is processed shortly # after configure starts and defines, among other things, flags for # the various compile modes. #---------------------------------------------------------------------------- # 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 $CC and is only # used within this file. if test "X-" = "X-$CC"; then CC=cc CC_BASENAME=cc fi # no need to use RANLIB RANLIB=: # 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 # usualy 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. # # 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 CFLAGS # variable if the compiler is the GNU gcc # compiler or a descendent of gcc such as EGCS or PGCC. # # The CFLAGS should contains *something* or else # configure will probably add `-g'. For most # systems this isn't a problem but some systems # will disable optimizations in favor of the # `-g'. # # # 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). case $CC_BASENAME in gcc) CFLAGS="$CFLAGS -Wsign-compare" #Only works for some versions DEBUG_CFLAGS="-g -fverbose-asm" DEBUG_CPPFLAGS= PROD_CFLAGS="-O3 -fomit-frame-pointer" PROD_CPPFLAGS= PROFILE_CFLAGS="-pg" PROFILE_CPPFLAGS= ;; cc) CFLAGS="$CFLAGS" DEBUG_CFLAGS="-g -h zero -h scalar0" DEBUG_CPPFLAGS= PROD_CFLAGS="-O2 -h scalar0" PROD_CPPFLAGS= PROFILE_CFLAGS="-pg" PROFILE_CPPFLAGS= ;; *) CFLAGS="$CFLAGS -ansi" DEBUG_CFLAGS="-g" DEBUG_CPPFLAGS= PROD_CFLAGS="-O" PROD_CPPFLAGS= PROFILE_CFLAGS="-pg" PROFILE_CPPFLAGS= ;; esac # Overriding Configure Tests # -------------------------- # # Values for overriding configuration tests when cross compiling. # This includes compiling on some machines where the serial front end # compiles for a parallel back end. # Set this to `yes' or `no' depending on whether the target is big # endian or little endian. ac_cv_c_bigendian=${ac_cv_c_bigendian='yes'} # Set this to the width required by printf() to print type `long # long'.
