# Options:
20
#
21 22 23
# --config      add the given configuration file, which will be read after
#               any "Configurations*" files that are found in the same
#               directory as this script.
24 25 26 27 28 29 30 31 32
# --prefix      prefix for the OpenSSL installation, which includes the
#               directories bin, lib, include, share/man, share/doc/openssl
#               This becomes the value of INSTALLTOP in Makefile
#               (Default: /usr/local)
# --openssldir  OpenSSL data area, such as openssl.cnf, certificates and keys.
#               If it's a relative directory, it will be added on the directory
#               given with --prefix.
#               This becomes the value of OPENSSLDIR in Makefile and in C.
#               (Default: PREFIX/ssl)
33 34 35 36 37
#
# --install_prefix  Additional prefix for package builders (empty by
#               default).  This needn't be set in advance, you can
#               just as well use "make INSTALL_PREFIX=/whatever install".
#
38 39
# --cross-compile-prefix Add specified prefix to binutils components.
#
40 41 42
# --api         One of 0.9.8, 1.0.0 or 1.1.0.  Do not compile support for
#               interfaces deprecated as of the specified OpenSSL version.
#
43 44 45 46 47
# no-hw-xxx     do not compile support for specific crypto hardware.
#               Generic OpenSSL-style methods relating to this support
#               are always compiled but return NULL if the hardware
#               support isn't compiled.
# no-hw         do not compile support for any crypto hardware.
48 49 50
# [no-]threads  [don't] try to create a library that is suitable for
#               multithreaded applications (default is "threads" if we
#               know how to do it)
51
# [no-]shared	[don't] try to create shared libraries when supported.

52

53 54
# no-dso        do not compile in any native shared-library methods. This
#               will ensure that all methods just return NULL.
55
# no-egd        do not compile support for the entropy-gathering daemon APIs
56 57 58
# [no-]zlib     [don't] compile support for zlib compression.
# zlib-dynamic	Like "zlib", but the zlib library is expected to be a shared
#		library and will be loaded in run-time by the OpenSSL library.

# the first is a regexp detecting a line continuation ending, and the
# following argument is a CODEref that takes care of concatenating two
# lines.
# All following arguments are regex/CODEref pairs, where the regexp detects a
# line and the CODEref does something with the result of the regexp.
