|
#
|
||
|
|
# AX_PERL_EXT_FLAGS([CFLAGS-VARIABLE], [LDFLAGS-VARIABLE], [EXTRA-MODULES])

# DESCRIPTION
|
||
|
|
#
|
||
|
|
# Fetches the linker flags and C compiler flags for compiling and linking
|
||
|
|
# programs that embed a Perl interpreter. If the EXTRA-MODULES argument is
|
||
|
|
# submitted, it is a space separated list of extra modules to link. The
|
||
|
|
# flags will be stored in the provided variables.
|
||
|
|
#
|
||
|
|
# Examples:
|
||
|
|
#
|
||
|
|
# AX_PERL_EXT_FLAGS([PERLXS_CFLAGS], [PERLXS_LDFLAGS])
|
||
|
|
# AC_SUBST([PERLXS_CFLAGS])
|
||
|
|
# AC_SUBST([PERLXS_LDFLAGS])

# AX_PERL_EXT_CFLAGS([PERLXS_CFLAGS])
