26 To build and install OpenSSL, you will need:
28 * DEC C or some other ANSI C compiler. VAX C is *not* supported.
29 [Note: OpenSSL has only been tested with DEC C. Compiling with
30 a different ANSI C compiler may require some work]
32 Checking the distribution:
33 ==========================
35 There have been reports of places where the distribution didn't quite get
36 through, for example if you've copied the tree from a NFS-mounted Unix
39 The easiest way to check if everything got through as it should is to check
40 for one of the following files:
42 [.CRYPTO]OPENSSLCONF.H_IN
43 [.CRYPTO]OPENSSLCONF_H.IN
45 They should never exist both at once, but one of them should (preferably
46 the first variant). If you can't find any of those two, something went
49 The best way to get a correct distribution is to download the gzipped tar
50 file from ftp://ftp.openssl.org/source/, use GUNZIP to uncompress it and
51 use VMSTAR to unpack the resulting tar file.
53 GUNZIP is available in many places on the net. One of the distribution
54 points is the WKU software archive, ftp://ftp.wku.edu/vms/fileserv/ .
56 VMSTAR is also available in many places on the net. The recommended place
57 to find information about it is http://www.free.lp.se/vmstar/ .
63 I've used the very good command procedures written by Robert Byer
64 <byer@mail.all-net.net>, and just slightly modified them, making
65 them slightly more general and easier to maintain.
67 You can actually compile in almost any directory separately. Look
68 for a command procedure name xxx-LIB.COM (in the library directories)
69 or MAKExxx.COM (in the program directories) and read the comments at
70 the top to understand how to use them. However, if you want to
71 compile all you can get, the simplest is to use MAKEVMS.COM in the top
72 directory. The syntax is the following:
74 @MAKEVMS <option> <rsaref-p> <debug-p> [<compiler>]
76 <option> must be one of the following:
78 ALL Just build "everything".
79 CONFIG Just build the "[.CRYPTO]OPENSSLCONF.H" file.
80 BUILDINF Just build the "[.INCLUDE]BUILDINF.H" file.
81 SOFTLINKS Just copies some files, to simulate Unix soft links.
82 BUILDALL Same as ALL, except CONFIG, BUILDINF and SOFTLINKS aren't done.
83 RSAREF Just build the "[.xxx.EXE.RSAREF]LIBRSAGLUE.OLB" library.
84 CRYPTO Just build the "[.xxx.EXE.CRYPTO]LIBCRYPTO.OLB" library.
85 SSL Just build the "[.xxx.EXE.SSL]LIBSSL.OLB" library.
86 SSL_TASK Just build the "[.xxx.EXE.SSL]SSL_TASK.EXE" program.
87 TEST Just build the "[.xxx.EXE.TEST]" test programs for OpenSSL.
88 APPS Just build the "[.xxx.EXE.APPS]" application programs for OpenSSL.
90 <rsaref-p> must be one of the following:
92 RSAREF compile using the RSAREF Library
93 NORSAREF compile without using RSAREF
95 Note 0: The RSAREF library IS NO LONGER NEEDED. The RSA patent
96 expires September 20, 2000, and RSA Security chose to make
97 the algorithm public domain two weeks before that.
99 Note 1: If you still want to use RSAREF, the library is NOT INCLUDED
100 and you have to download it. RSA Security doesn't carry it
101 any more, but there are a number of places where you can find
102 it. You have to get the ".tar-Z" file as the ".zip" file
103 doesn't have the directory structure stored. You have to
104 extract the file into the [.RSAREF] directory as that is where
105 the scripts will look for the files.
107 Note 2: I have never done this, so I've no idea if it works or not.
109 <debug-p> must be one of the following:
111 DEBUG compile with debugging info (will not optimize)
112 NODEBUG compile without debugging info (will optimize)
114 <compiler> must be one of the following:
120 You will find the crypto library in [.xxx.EXE.CRYPTO], called LIBCRYPTO.OLB,
121 where xxx is VAX or AXP. You will find the SSL library in [.xxx.EXE.SSL],
122 named LIBSSL.OLB, and you will find a bunch of useful programs in
123 [.xxx.EXE.APPS]. However, these shouldn't be used right off unless it's
124 just to test them. For production use, make sure you install first, see
127 Note 1: Some programs in this package require a TCP/IP library.
129 Note 2: if you want to compile the crypto library only, please make sure
130 you have at least done a @MAKEVMS CONFIG, a @MAKEVMS BUILDINF and
131 a @MAKEVMS SOFTLINKS. A lot of things will break if you don't.
137 There are a few things that can't currently be given through the command
138 line. Instead, logical names are used.
140 Currently, the logical names supported are:
142 OPENSSL_NO_ASM with value YES, the assembler parts of OpenSSL will
143 not be used. Instead, plain C implementations are
144 used. This is good to try if something doesn't work.
145 OPENSSL_NO_'alg' with value YES, the corresponding crypto algorithm
146 will not be implemented. Supported algorithms to
147 do this with are: RSA, DSA, DH, MD2, MD4, MD5, RIPEMD,
148 SHA, DES, MDC2, CR2, RC4, RC5, IDEA, BF, CAST, HMAC,
149 SSL2. So, for example, having the logical name
150 OPENSSL_NO_RSA with the value YES means that the
151 LIBCRYPTO.OLB library will not contain an RSA
158 Testing is very simple, just do the following:
162 If a test fails, try with defining the logical name OPENSSL_NO_ASM (yes,
163 it's an ugly hack!) and rebuild. Please send a bug report to
164 <openssl-bugs@openssl.org>, including the output of "openssl version -a"
165 and of the failed test.
171 Installation is easy, just do the following:
175 <root> is the directory in which everything will be installed,
176 subdirectories, libraries, header files, programs and startup command
179 N.B.: INSTALL.COM builds a new directory structure, different from
180 the directory tree where you have now build OpenSSL.
182 In the [.VMS] subdirectory of the installation, you will find the
183 following command procedures:
187 defines all needed logical names. Takes one argument that
188 tells it in what logical name table to insert the logical
189 names. If you insert if it SYS$MANAGER:SYSTARTUP_VMS.COM, the
190 call should look like this:
192 @openssldev:[openssldir.VMS]OPENSSL_STARTUP "/SYSTEM"
196 sets up the symbols to the applications. Should be called
197 from for example SYS$MANAGER:SYLOGIN.COM
199 The logical names that are set up are the following:
201 SSLROOT a dotted concealed logical name pointing at the
204 SSLCERTS Initially an empty directory, this is the default
205 location for certificate files.
206 SSLMISC Various scripts.
207 SSLPRIVATE Initially an empty directory, this is the default
208 location for private key files.
210 SSLEXE Contains the openssl binary and a few other utility
212 SSLINCLUDE Contains the header files needed if you want to
213 compile programs with libcrypto or libssl.
214 SSLLIB Contains the OpenSSL library files (LIBCRYPTO.OLB
215 and LIBSSL.OLB) themselves.
217 OPENSSL Same as SSLINCLUDE. This is because the standard
218 way to include OpenSSL header files from version
221 #include <openssl/header.h>
223 For more info on this issue, see the INSTALL. file
224 (the NOTE in section 4 of "Installation in Detail").
225 You don't need to "deleting old header files"!!!
228 Backward portability:
229 =====================
231 One great problem when you build a library is making sure it will work
232 on as many versions of VMS as possible. Especially, code compiled on
233 OpenVMS version 7.x and above tend to be unusable in version 6.x or
234 lower, because some C library routines have changed names internally
235 (the C programmer won't usually see it, because the old name is
236 maintained through C macros). One obvious solution is to make sure
237 you have a development machine with an old enough version of OpenVMS.
238 However, if you are stuck with a bunch of Alphas running OpenVMS version
239 7.1, you seem to be out of luck. Fortunately, the DEC C header files
240 are cluttered with conditionals that make some declarations and definitions
241 dependent on the OpenVMS version or the C library version, *and* you
242 can use those macros to simulate older OpenVMS or C library versions,
243 by defining the macros _VMS_V6_SOURCE, __VMS_VER and __CTRL_VER with
244 correct values. In the compilation scripts, I've provided the possibility
245 for the user to influence the creation of such macros, through a bunch of
246 symbols, all having names starting with USER_. Here's the list of them:
248 USER_CCFLAGS - Used to give additional qualifiers to the
249 compiler. It can't be used to define macros
250 since the scripts will do such things as well.
251 To do such things, use USER_CCDEFS.
252 USER_CCDEFS - Used to define macros on the command line. The
253 value of this symbol will be inserted inside a
255 USER_CCDISABLEWARNINGS - Used to disable some warnings. The value is
256 inserted inside a /DISABLE=WARNING=(...).
258 So, to maintain backward compatibility with older VMS versions, do the
259 following before you start compiling:
261 $ USER_CCDEFS := _VMS_V6_SOURCE=1,__VMS_VER=60000000,__CRTL_VER=60000000
262 $ USER_CCDISABLEWARNINGS := PREOPTW
264 The USER_CCDISABLEWARNINGS is there because otherwise, DEC C will complain
265 that those macros have been changed.
267 Note: Currently, this is only useful for library compilation. The
268 programs will still be linked with the current version of the
269 C library shareable image, and will thus complain if they are
270 faced with an older version of the same C library shareable image.
271 This will probably be fixed in a future revision of OpenSSL.
274 Possible bugs or quirks:
275 ========================
277 I'm not perfectly sure all the programs will use the SSLCERTS:
278 directory by default, it may very well be that you have to give them
279 extra arguments. Please experiment.
285 There are a few things that need to be worked out in the VMS version of
288 - Description files. ("Makefile's" :-))
289 - Script code to link an already compiled build tree.
290 - A VMSINSTALlable version (way in the future, unless someone else hacks).
291 - shareable images (DLL for you Windows folks).
293 There may be other things that I have missed and that may be desirable.
