30 # given with --prefix.

40 # --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
41 # interfaces deprecated as of the specified OpenSSL version.

49 # multithreaded applications (default is "threads" if we
51 # [no-]shared [don't] try to create shared libraries when supported.
52 # no-asm do not use assembler
53 # no-dso do not compile in any native shared-library methods. This
54 # will ensure that all methods just return NULL.
55 # no-egd do not compile support for the entropy-gathering daemon APIs
56 # [no-]zlib [don't] compile support for zlib compression.

58 # library and will be loaded in run-time by the OpenSSL library.
