| 7 | # CHECK_SSL |
|---|
| 8 | # |
|---|
| 9 | # DESCRIPTION |
|---|
| 10 | # |
|---|
| 11 | # This macro will check various standard spots for OpenSSL including a |
|---|
| 12 | # user-supplied directory. The user uses '--with-ssl' or |
|---|
| 13 | # '--with-ssl=/path/to/ssl' as arguments to configure. |
|---|
| 14 | # |
|---|
| 15 | # If OpenSSL is found the include directory gets added to CFLAGS and |
|---|
| 16 | # CXXFLAGS as well as '-DHAVE_SSL', '-lssl' & '-lcrypto' get added to |
|---|
| 17 | # LIBS, and the libraries location gets added to LDFLAGS. Finally |
|---|
| 18 | # 'HAVE_SSL' gets set to 'yes' for use in your Makefile.in I use it like |
|---|
| 19 | # so (valid for gmake): |
|---|
| 20 | # |
|---|
| 21 | # HAVE_SSL = @HAVE_SSL@ |
|---|
| 22 | # ifeq ($(HAVE_SSL),yes) |
|---|
| 23 | # SRCS+= @srcdir@/my_file_that_needs_ssl.c |
|---|
| 24 | # endif |
|---|
| 25 | # |
|---|
| 26 | # For bsd 'bmake' use: |
|---|
| 27 | # |
|---|
| 28 | # .if ${HAVE_SSL} == "yes" |
|---|
| 29 | # SRCS+= @srcdir@/my_file_that_needs_ssl.c |
|---|
| 30 | # .endif |
