Heres a few comments about building OpenSSL in Windows environments. Most
|
|
|
|
of this is tested on Win32 but it may also work in Win 3.1 with some
|
2000-02-03 23:23:24 +00:00
|
|
|
modification.

You need Perl for Win32. Unless you will build on Cygwin, you will need
|
2002-01-03 18:53:47 +00:00
|
|
|
ActiveState Perl, available from http://www.activestate.com/ActivePerl.
|
2002-02-16 22:44:30 +00:00
|
|
|
For Cygwin users, there's more info in the Cygwin section.
|
2002-01-02 11:25:17 +00:00
|
|
|
|
1999-05-06 00:46:34 +00:00
|
|
|
and one of the following C compilers:
|
1999-03-03 02:01:26 +00:00
|
|
|
|
1999-05-06 00:46:34 +00:00
|
|
|
* Visual C++
|
|
|
|
* Borland C
|
2002-02-16 22:44:30 +00:00
|
|
|
* GNU C (Mingw32 or Cygwin)

|
|
|
If you want to compile in the assembly language routines with Visual C++ then
|
|
|
|
you will need an assembler. This is worth doing because it will result in
|
|
|
|
faster code: for example it will typically result in a 2 times speedup in the
|
|
|
|
RSA routines. Currently the following assemblers are supported:
|
|
|
|
|
|
|
|
* Microsoft MASM (aka "ml")
|
|
|
|
* Free Netwide Assembler NASM.
|
|
|
|
|
2000-02-27 01:15:25 +00:00
|
|
|
MASM was at one point distributed with VC++. It is now distributed with some
|
2000-02-27 02:19:48 +00:00
|
|
|
Microsoft DDKs, for example the Windows NT 4.0 DDK and the Windows 98 DDK. If
|
|
|
|
you do not have either of these DDKs then you can just download the binaries
|
|
|
|
for the Windows 98 DDK and extract and rename the two files XXXXXml.exe and
|
|
|
|
XXXXXml.err, to ml.exe and ml.err and install somewhere on your PATH. Both
|
|
|
|
DDKs can be downloaded from the Microsoft developers site www.msdn.com.
|
1999-07-12 23:35:10 +00:00
|
|
|
|
|
|
|
NASM is freely available. Version 0.98 was used during testing: other versions
|
|
|
|
may also work. It is available from many places, see for example:
|
|
|
|
http://www.kernel.org/pub/software/devel/nasm/binaries/win32/
|
|
|
|
The NASM binary nasmw.exe needs to be installed anywhere on your PATH.
|
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
If you are compiling from a tarball or a CVS snapshot then the Win32 files
|
|
|
|
may well be not up to date. This may mean that some "tweaking" is required to
|
|
|
|
get it all to work. See the trouble shooting section later on for if (when?)
|
|
|
|
it goes wrong.

|
|
|
----------
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-07-12 23:35:10 +00:00
|
|
|
Firstly you should run Configure:
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-05-06 00:46:34 +00:00
|
|
|
> perl Configure VC-WIN32
|
1999-07-12 23:35:10 +00:00
|
|
|
|
|
|
|
Next you need to build the Makefiles and optionally the assembly language
|
1999-08-03 20:19:04 +00:00
|
|
|
files:
|
1999-07-12 23:35:10 +00:00
|
|
|
|
1999-08-03 20:19:04 +00:00
|
|
|
- If you are using MASM then run:
|
1999-07-12 23:35:10 +00:00
|
|
|
|
1999-08-03 20:19:04 +00:00
|
|
|
> ms\do_masm
|
1999-07-12 23:35:10 +00:00
|
|
|
|
1999-08-03 20:19:04 +00:00
|
|
|
- If you are using NASM then run:
|
1999-07-12 23:35:10 +00:00
|
|
|
|
1999-08-03 20:19:04 +00:00
|
|
|
> ms\do_nasm
|
1999-07-12 23:35:10 +00:00
|
|
|
|
1999-08-03 20:19:04 +00:00
|
|
|
- If you don't want to use the assembly language files at all then run:
|
1999-07-12 23:35:10 +00:00
|
|
|
|
1999-08-03 20:19:04 +00:00
|
|
|
> ms\do_ms
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
If you get errors about things not having numbers assigned then check the
|
2000-02-27 02:19:48 +00:00
|
|
|
troubleshooting section: you probably won't be able to compile it as it
|
1999-03-22 15:36:37 +00:00
|
|
|
stands.
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
Then from the VC++ environment at a prompt do:
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
> nmake -f ms\ntdll.mak
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
If all is well it should compile and you will have some DLLs and executables
|
|
|
|
in out32dll. If you want to try the tests then do:
|
|
|
|
|
|
|
|
> cd out32dll
|
|
|
|
> ..\ms\test
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-05-06 00:46:34 +00:00
|
|
|
Tweaks:
|
|
|
|
|
1999-07-12 23:35:10 +00:00
|
|
|
There are various changes you can make to the Win32 compile environment. By
|
|
|
|
default the library is not compiled with debugging symbols. If you add 'debug'
|
2002-03-25 17:11:25 +00:00
|
|
|
to the mk1mf.pl lines in the do_* batch file then debugging symbols will be
|
1999-07-12 23:35:10 +00:00
|
|
|
compiled in.
|
1999-05-06 00:46:34 +00:00
|
|
|
|
|
|
|
The default Win32 environment is to leave out any Windows NT specific
|
|
|
|
features.
|
|
|
|
|
|
|
|
If you want to enable the NT specific features of OpenSSL (currently only the
|
|
|
|
logging BIO) follow the instructions above but call the batch file do_nt.bat
|
|
|
|
instead of do_ms.bat.
|
|
|
|
|
|
|
|
You can also build a static version of the library using the Makefile
|
|
|
|
ms\nt.mak
|
|
|
|
|
|
|
|
Borland C++ builder 3 and 4
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
* Setup PATH. First must be GNU make then bcb4/bin
|
|
|
|
|
|
|
|
* Run ms\bcb4.bat
|
|
|
|
|
|
|
|
* Run make:
|
|
|
|
> make -f bcb.mak
|
|
|
|
|
|
|
|
GNU C (Mingw32)
|
|
|
|
---------------
|
|
|
|
|
|
|
|
To build OpenSSL, you need the Mingw32 package and GNU make.
|
|
|
|
|
1999-05-07 22:55:27 +00:00
|
|
|
* Compiler installation:
|
1999-05-06 01:29:57 +00:00
|
|
|
|
2000-09-23 02:06:08 +00:00
|
|
|
Mingw32 is available from <ftp://ftp.xraylith.wisc.edu/pub/khan/
|
2002-05-14 17:19:26 +00:00
|
|
|
gnu-win32/mingw32/gcc-2.95.2/gcc-2.95.2-msvcrt.exe>. Extract it
|
|
|
|
to a directory such as C:\gcc-2.95.2 and add c:\gcc-2.95.2\bin to
|
|
|
|
the PATH environment variable in "System Properties"; or edit and
|
|
|
|
run C:\gcc-2.95.2\mingw32.bat to set the PATH.
|
1999-05-06 00:46:34 +00:00
|
|
|
|
1999-05-07 22:55:27 +00:00
|
|
|
* Compile OpenSSL:
|
1999-05-06 00:46:34 +00:00
|
|
|
|
2000-02-28 21:04:10 +00:00
|
|
|
> ms\mingw32
|
1999-05-06 00:46:34 +00:00
|
|
|
|
2000-02-28 21:04:10 +00:00
|
|
|
This will create the library and binaries in out. In case any problems
|
|
|
|
occur, try
|
|
|
|
> ms\mingw32 no-asm
|
|
|
|
instead.
|
1999-05-06 00:46:34 +00:00
|
|
|
|
1999-05-07 22:55:27 +00:00
|
|
|
libcrypto.a and libssl.a are the static libraries. To use the DLLs,
|
|
|
|
link with libeay32.a and libssl32.a instead.
|
1999-05-06 00:46:34 +00:00
|
|
|
|
1999-05-07 22:55:27 +00:00
|
|
|
See troubleshooting if you get error messages about functions not having
|
|
|
|
a number assigned.
|
1999-05-06 00:46:34 +00:00
|
|
|
|
1999-05-07 22:55:27 +00:00
|
|
|
* You can now try the tests:
|
1999-05-06 00:46:34 +00:00
|
|
|
|
|
|
|
> cd out
|
|
|

GNU C (Cygwin)
|
|
|
|
--------------
|
2000-06-03 23:23:10 +00:00
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
Cygwin provides a bash shell and GNU tools environment running on
|
2000-06-03 23:23:10 +00:00
|
|
|
NT 4.0, Windows 9x and Windows 2000. Consequently, a make of OpenSSL
|
2002-02-16 22:44:30 +00:00
|
|
|
with Cygwin is closer to a GNU bash environment such as Linux rather
|
2000-06-03 23:23:10 +00:00
|
|
|
than other W32 makes that are based on a single makefile approach.
|
2002-02-16 22:44:30 +00:00
|
|
|
Cygwin implements Posix/Unix calls through cygwin1.dll, and is
|
2000-06-03 23:23:10 +00:00
|
|
|
contrasted to Mingw32 which links dynamically to msvcrt.dll or
|
|
|
|
crtdll.dll.
|
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
To build OpenSSL using Cygwin:
|
2000-06-03 23:23:10 +00:00
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
* Install Cygwin (see http://sourceware.cygnus.com/cygwin)
|
2000-06-03 23:23:10 +00:00
|
|
|
|
2002-01-03 18:53:47 +00:00
|
|
|
* Install Perl and ensure it is in the path (recent Cygwin perl
|
|
|
|
(version 5.6.1-2 of the latter has been reported to work) or
|
2001-09-05 02:27:07 +00:00
|
|
|
ActivePerl)
|
2000-06-03 23:23:10 +00:00
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
* Run the Cygwin bash shell
|
2000-06-03 23:23:10 +00:00
|
|
|
|
|
|
|
* $ tar zxvf openssl-x.x.x.tar.gz
|
|
|
|
$ cd openssl-x.x.x
|
2002-02-16 22:44:30 +00:00
|
|
|
$ ./config
|
2000-06-03 23:23:10 +00:00
|
|
|
[...]
|
|
|
|
$ make
|
|
|
|
[...]
|
|
|
|
$ make test
|
|
|
|
$ make install
|
|
|
|
|
|
|
|
This will create a default install in /usr/local/ssl.

Cygwin Notes:
|
2000-06-03 23:23:10 +00:00
|
|
|
|
|
|
|
"make test" and normal file operations may fail in directories
|
2002-02-16 22:44:30 +00:00
|
|
|
mounted as text (i.e. mount -t c:\somewhere /home) due to Cygwin
|
2000-06-03 23:23:10 +00:00
|
|
|
stripping of carriage returns. To avoid this ensure that a binary
|
|
|
|
mount is used, e.g. mount -b c:\somewhere /home.
|
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
As of version 1.1.1 Cygwin is relatively unstable in its handling
|
2000-06-03 23:23:10 +00:00
|
|
|
of cr/lf issues. These make procedures succeeded with versions 1.1 and
|
|
|
|
the snapshot 20000524 (Slow!).
|
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
"bc" is not provided in the Cygwin distribution. This causes a
|
2000-06-03 23:23:10 +00:00
|
|
|
non-fatal error in "make test" but is otherwise harmless. If
|
2002-02-16 22:44:30 +00:00
|
|
|
desired, GNU bc can be built with Cygwin without change.

Installation
|
|
|
|
------------
|
|
|
|
|
2002-02-16 22:44:30 +00:00
|
|
|
If you used the Cygwin procedure above, you have already installed and
|
2002-01-03 18:53:47 +00:00
|
|
|
can skip this section. For all other procedures, there's currently no real
|
|
|
|
installation procedure for Win32. There are, however, some suggestions:
|
2000-07-24 09:57:02 +00:00
|
|
|
|
|
|
|
- do nothing. The include files are found in the inc32/ subdirectory,
|
|
|
|
all binaries are found in out32dll/ or out32/ depending if you built
|
|
|
|
dynamic or static libraries.
|
|
|
|
|
|
|
|
- do as is written in INSTALL.Win32 that comes with modssl:
|
|
|
|
|
|
|
|
$ md c:\openssl
|
|
|
|
$ md c:\openssl\bin
|
|
|
|
$ md c:\openssl\lib
|
|
|
|
$ md c:\openssl\include
|
|
|
|
$ md c:\openssl\include\openssl
|
|
|
|
$ copy /b inc32\* c:\openssl\include\openssl
|
|
|
|
$ copy /b out32dll\ssleay32.lib c:\openssl\lib
|
|
|
|
$ copy /b out32dll\libeay32.lib c:\openssl\lib
|
|
|
|
$ copy /b out32dll\ssleay32.dll c:\openssl\bin
|
|
|
|
$ copy /b out32dll\libeay32.dll c:\openssl\bin
|
|
|
|
$ copy /b out32dll\openssl.exe c:\openssl\bin
|
|
|
|
|
|
|
|
Of course, you can choose another device than c:. C: is used here
|
|
|
|
because that's usually the first (and often only) harddisk device.
|
|
|
|
Note: in the modssl INSTALL.Win32, p: is used rather than c:.

Troubleshooting
|
|
|
|
---------------
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
Since the Win32 build is only occasionally tested it may not always compile
|
|
|
|
cleanly. If you get an error about functions not having numbers assigned
|
|
|
|
when you run ms\do_ms then this means the Win32 ordinal files are not up to
|
|
|
|
date. You can do:
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-03-22 15:36:37 +00:00
|
|
|
> perl util\mkdef.pl crypto ssl update
|
1999-02-14 00:40:13 +00:00
|
|
|
|
1999-07-12 23:35:10 +00:00
|
|
|
then ms\do_XXX should not give a warning any more. However the numbers that
|
1999-03-22 15:36:37 +00:00
|
|
|
get assigned by this technique may not match those that eventually get
|
|
|
|
assigned in the CVS tree: so anything linked against this version of the
|
|
|
|

If you get errors about unresolved symbols there are several possible
|
|
|
|
causes.

If this happens when the DLL is being linked and you have disabled some
|
|
|
|
ciphers then it is possible the DEF file generator hasn't removed all
|
|
|
|
the disabled symbols: the easiest solution is to edit the DEF files manually
|
|
|
|
to delete them. The DEF files are ms\libeay32.def ms\ssleay32.def.
|
|
|
|
|
|
|
|
Another cause is if you missed or ignored the errors about missing numbers
|
|
|
|
mentioned above.

If you get warnings in the code then the compilation will halt.

The default Makefile for Win32 halts whenever any warnings occur. Since VC++
|
|
|
|
has its own ideas about warnings which don't always match up to other
|
|
|
|
environments this can happen. The best fix is to edit the file with the
|
|
|
|
warning in and fix it. Alternatively you can turn off the halt on warnings by
|
|
|
|
editing the CFLAG line in the Makefile and deleting the /WX option.

You might get compilation errors. Again you will have to fix these or report
|
|
|
|
them.

One final comment about compiling applications linked to the OpenSSL library.
|
|
|
|
If you don't use the multithreaded DLL runtime library (/MD option) your
|
2000-01-13 09:18:42 +00:00
|
|
|
program will almost certainly crash because malloc gets confused -- the
|
|
|
|
OpenSSL DLLs are statically linked to one version, the application must
|
|
|
|
not use a different one. You might be able to work around such problems
|
|
|
|
by adding CRYPTO_malloc_init() to your program before any calls to the
|
|
|
|
OpenSSL libraries: This tells the OpenSSL libraries to use the same
|
|
|
|
malloc(), free() and realloc() as the application. However there are many
|
|
|
|
standard library functions used by OpenSSL that call malloc() internally
|
|
|
|
(e.g. fopen()), and OpenSSL cannot change these; so in general you cannot
|
2001-09-07 06:13:40 +00:00
|
|
|
rely on CRYPTO_malloc_init() solving your problem, and you should
|
2000-01-13 09:18:42 +00:00
|
|
|
consistently use the multithreaded library.
