#               directory as this script.
21 22 23 24 25 26 27 28 29
# --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)
30
#
31 32
# --cross-compile-prefix Add specified prefix to binutils components.
#
33 34 35
# --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.
#
36 37 38 39 40
# no-hw-xxx     do not compile support for specific crypto hardware.
#               Generic OpenSSL-style methods relating to this support

#               support isn't compiled.
# no-hw         do not compile support for any crypto hardware.
41 42 43
# [no-]threads  [don't] try to create a library that is suitable for

# [no-]shared	[don't] try to create shared libraries when supported.
45
# [no-]pic      [don't] try to build position independent code when supported.

51 52 53
# [no-]zlib     [don't] compile support for zlib compression.
# zlib-dynamic	Like "zlib", but the zlib library is expected to be a shared
