# SYNOPSIS
|
|
|
|
|
#
|
|
|
|
|
# CHECK_SSL
|
|
|
|
|
#
|
|
|
|
|
# DESCRIPTION
|
|
|
|
|
#
|
|
|
|
|
# This macro will check various standard spots for OpenSSL including a
|
|
|
|
|
# user-supplied directory. The user uses '--with-ssl' or
|
|
|
|
|
# '--with-ssl=/path/to/ssl' as arguments to configure.
|
|
|
|
|
#
|
|
|
|
|
# If OpenSSL is found the include directory gets added to CFLAGS and
|
|
|
|
|
# CXXFLAGS as well as '-DHAVE_SSL', '-lssl' & '-lcrypto' get added to
|
|
|
|
|
# LIBS, and the libraries location gets added to LDFLAGS. Finally
|
|
|
|
|
# 'HAVE_SSL' gets set to 'yes' for use in your Makefile.in I use it like
|
|
|
|
|
# so (valid for gmake):
|
|
|
|
|
#
|
|
|
|
|
# HAVE_SSL = @HAVE_SSL@
|
|
|
|
|
# ifeq ($(HAVE_SSL),yes)
|
|
|
|
|
# SRCS+= @srcdir@/my_file_that_needs_ssl.c
|
|
|
|
|
# endif
|
|
|
|
|
#
|
|
|
|
|
# For bsd 'bmake' use:
|
|
|
|
|
#
|
|
|
|
|
# .if ${HAVE_SSL} == "yes"
|
|
|
|
|
# SRCS+= @srcdir@/my_file_that_needs_ssl.c
|
|
|
|
|
# .endif
