ax_append_compile_flags

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.
