# SYNOPSIS |
|||
# |
|||
# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT]) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# For every FLAG1, FLAG2 it is checked whether the compiler works with the |
|||
# flag. If it does, the flag is added FLAGS-VARIABLE |
|||
# |
|||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g. |
|||
# CFLAGS) is used. During the check the flag is always added to the |
|||
# current language's flags. |
|||
# |
|||
# If EXTRA-FLAGS is defined, it is added to the current language's default |
|||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with |
|||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to |
|||
# force the compiler to issue an error when a bad flag is given. |
|||
# |
|||
# INPUT gives an alternative input source to AC_COMPILE_IFELSE. |
|||
# |
|||
# NOTE: This macro depends on the AX_APPEND_FLAG and |
|||
# AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with |
|||
# AX_APPEND_LINK_FLAGS. |

# SYNOPSIS |
|||
# |
|||
# 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. |

# SYNOPSIS |
|||
# |
|||
# AX_REQUIRE_DEFINED(MACRO) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have |
|||
# been defined and thus are available for use. This avoids random issues |
|||
# where a macro isn't expanded. Instead the configure script emits a |
|||
# non-fatal: |
|||
# |
|||
# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found |
|||
# |
|||
# It's like AC_REQUIRE except it doesn't expand the required macro. |
|||

|||
