24# directory as this script.
25# --prefix prefix for the OpenSSL installation, which includes the
26# directories bin, lib, include, share/man, share/doc/openssl
27# This becomes the value of INSTALLTOP in Makefile
28# (Default: /usr/local)
29# --openssldir OpenSSL data area, such as openssl.cnf, certificates and keys.
30# If it's a relative directory, it will be added on the directory
31# given with --prefix.
32# This becomes the value of OPENSSLDIR in Makefile and in C.
33# (Default: PREFIX/ssl)
34#
35# --cross-compile-prefix Add specified prefix to binutils components.
36#
37# --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
38# interfaces deprecated as of the specified OpenSSL version.
39#
40# no-hw-xxx do not compile support for specific crypto hardware.
41# Generic OpenSSL-style methods relating to this support
42# are always compiled but return NULL if the hardware
43# support isn't compiled.
44# no-hw do not compile support for any crypto hardware.
45# [no-]threads [don't] try to create a library that is suitable for
46# multithreaded applications (default is "threads" if we
47# know how to do it)
48# [no-]shared [don't] try to create shared libraries when supported.
49# no-asm do not use assembler
50# no-dso do not compile in any native shared-library methods. This
51# will ensure that all methods just return NULL.
52# no-egd do not compile support for the entropy-gathering daemon APIs
53# [no-]zlib [don't] compile support for zlib compression.
54# zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
55# library and will be loaded in run-time by the OpenSSL library.
56# sctp include SCTP support
57# 386 generate 80386 code
58# no-sse2 disables IA-32 SSE2 code, above option implies no-sse2
59# no-<cipher> build without specified algorithm (rsa, idea, rc5, ...)
60# -<xxx> +<xxx> compiler options are passed through
61#
62# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
63# provided to stack calls. Generates unique stack functions for
64# each possible stack type.
65# BN_LLONG use the type 'long long' in crypto/bn/bn.h
66# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h

1863
1864 make clean # Clean the current configuration away
1865 mkdir $plausible_builddir
1866 cd $plausible_builddir
1867 $plausible_to_sourcedir/config --unified
