Return +# the value in the variable $ax_enable_debug. +# +# Specifying 'yes' adds '-g -O0' to the compilation flags for all +# languages. Specifying 'info' adds '-g' to the compilation flags. +# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to +# the linking flags. Otherwise, nothing is added. +# +# Define the variables listed in the second argument if debug is enabled, +# defaulting to no variables. Defines the variables listed in the third +# argument if debug is disabled, defaulting to NDEBUG. All lists of +# variables should be space-separated. +# +# If debug is not enabled, ensure AC_PROG_* will not add debugging flags. +# Should be invoked prior to any AC_PROG_* compiler checks. +# +# IS-RELEASE can be used to change the default to 'no' when making a +# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it +# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE +# macro, there is no need to pass this parameter. +# +# AX_IS_RELEASE([git-directory]) +# AX_CHECK_ENABLE_DEBUG() +# +# LICENSE +# +# Copyright (c) 2011 Rhys Ulerich +# Copyright (c) 2014, 2015 Philip Withnall +# +# SPDX-License-Identifier: FSFAP + +#serial 5 + +AC_DEFUN([AX_CHECK_ENABLE_DEBUG],[ + AC_BEFORE([$0],[AC_PROG_CC])dnl + AC_BEFORE([$0],[AC_PROG_CXX])dnl + AC_BEFORE([$0],[AC_PROG_F77])dnl + AC_BEFORE([$0],[AC_PROG_FC])dnl + + AC_MSG_CHECKING(whether to enable debugging) + + ax_enable_debug_default=m4_tolower(m4_normalize(ifelse([$1],,[no],[$1]))) + ax_enable_debug_is_release=m4_tolower(m4_normalize(ifelse([$4],, + [$ax_is_release], + [$4]))) + + # If this is a release, override the default. + AS_IF([test "$ax_enable_debug_is_release" = "yes"], + [ax_enable_debug_default="no"]) + + m4_define(ax_enable_debug_vars,[m4_normalize(ifelse([$2],,,[$2]))]) + m4_define(ax_disable_debug_vars,[m4_normalize(ifelse([$3],,[NDEBUG],[$3]))]) + + AC_ARG_ENABLE(debug, + [AS_HELP_STRING([--enable-debug=]@<:@yes/info/profile/no@:>@,[compile with debugging])], + [],enable_debug=$ax_enable_debug_default) + + # empty mean debug yes + AS_IF([test "x$enable_debug" = "x"], + [enable_debug="yes"]) + + # case of debug + AS_CASE([$enable_debug], + [yes],[ + AC_MSG_RESULT(yes) + CFLAGS="${CFLAGS} -g -O0" + CXXFLAGS="${CXXFLAGS} -g -O0" + FFLAGS="${FFLAGS} -g -O0" + FCFLAGS="${FCFLAGS} -g -O0" + OBJCFLAGS="${OBJCFLAGS} -g -O0" + ], + [info],[ + AC_MSG_RESULT(info) + CFLAGS="${CFLAGS} -g" + CXXFLAGS="${CXXFLAGS} -g" + FFLAGS="${FFLAGS} -g" + FCFLAGS="${FCFLAGS} -g" + OBJCFLAGS="${OBJCFLAGS} -g" + ], + [profile],[ + AC_MSG_RESULT(profile) + CFLAGS="${CFLAGS} -g -pg" + CXXFLAGS="${CXXFLAGS} -g -pg" + FFLAGS="${FFLAGS} -g -pg" + FCFLAGS="${FCFLAGS} -g -pg" + OBJCFLAGS="${OBJCFLAGS} -g -pg" + LDFLAGS="${LDFLAGS} -pg" + ], + [ + AC_MSG_RESULT(no) + dnl Ensure AC_PROG_CC/CXX/F77/FC/OBJC will not enable debug flags + dnl by setting any unset environment flag variables + AS_IF([test "x${CFLAGS+set}" != "xset"], + [CFLAGS=""]) + AS_IF([test "x${CXXFLAGS+set}" != "xset"], + [CXXFLAGS=""]) + AS_IF([test "x${FFLAGS+set}" != "xset"], + [FFLAGS=""]) + AS_IF([test "x${FCFLAGS+set}" != "xset"], + [FCFLAGS=""]) + AS_IF([test "x${OBJCFLAGS+set}" != "xset"], + [OBJCFLAGS=""]) + ]) + + dnl Define various variables if debugging is disabled. + dnl assert.h is a NOP if NDEBUG is defined, so define it by default. + AS_IF([test "x$enable_debug" = "xyes"], + [m4_map_args_w(ax_enable_debug_vars, [AC_DEFINE(], [,,[Define if debugging is enabled])])], + [m4_map_args_w(ax_disable_debug_vars, [AC_DEFINE(], [,,[Define if debugging is disabled])])]) + ax_enable_debug=$enable_debug +]) -- cgit v1.2.3
