INSTALLATION ON THE WIN32 PLATFORM
----------------------------------
- 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

+ modification.
+
+ You need Perl for Win32. Unless you will build on Cygwin, you will need
+ ActiveState Perl, available from http://www.activestate.com/ActivePerl.
- You will Perl for Win32 (available from http://activestate.com/ActivePerl)
and one of the following C compilers:
* Visual C++
* Borland C
- * GNU C (Mingw32 or Cygwin32)
+ * GNU C (Cygwin or MinGW)
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
Visual C++
----------
- Firstly you should run Configure and build the Win32 Makefiles:
+ 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.
+
+ MASM is distributed with most versions of VC++. For the versions where it is
+ not included in VC++, it is also distributed with some 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.
+
+ 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.
+
+ Firstly you should run Configure (to build a FIPS-certified variant of
+ OpenSSL, add the option "fips"):
> perl Configure VC-WIN32
- > ms\do_ms
+
+ Next you need to build the Makefiles and optionally the assembly language
+ files (to build a FIPS-certified variant of OpenSSL, add the argument "fips"):
+
+ - If you are using MASM then run:
+
+ > ms\do_masm
+
+ - If you are using NASM then run:
+
+ > ms\do_nasm
+
+ - If you don't want to use the assembly language files at all then run:
+
+ > ms\do_ms
If you get errors about things not having numbers assigned then check the
- troubleshooting section: you probably wont be able to compile it as it
+ troubleshooting section: you probably won't be able to compile it as it
stands.
Then from the VC++ environment at a prompt do:
Tweaks:
- There are various changes you can make to the Win32 compile environment. If
- you have the MASM assembler 'ml' then you can try the assembly language code.
- To do this remove the 'no-asm' part from do_ms.bat. You can also add 'debug'
- here to make a debugging version of the library.
+ 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'
+ to the mk1mf.pl lines in the do_* batch file then debugging symbols will be
+ compiled in. Note that mk1mf.pl expects the platform to be the last argument
+ on the command line, so 'debug' must appear before that, as all other options.
The default Win32 environment is to leave out any Windows NT specific
features.
You can also build a static version of the library using the Makefile
ms\nt.mak
+ Borland C++ builder 5
+ ---------------------
+
+ * Configure for building with Borland Builder (to build a FIPS-certified
+ variant of OpenSSL, add the option "fips"):
+ > perl Configure BC-32
+
+ * Create the appropriate makefile (to build a FIPS-certified variant of
+ OpenSSL, add the argument "fips")
+ > ms\do_nasm
+
+ * Build
+ > make -f ms\bcb.mak
+
Borland C++ builder 3 and 4
---------------------------
* Run make:
> make -f bcb.mak
- GNU C (Mingw32)
- ---------------
+ GNU C (Cygwin)
+ --------------
+
+ Cygwin provides a bash shell and GNU tools environment running
+ on NT 4.0, Windows 9x, Windows ME, Windows 2000, and Windows XP.
+ Consequently, a make of OpenSSL with Cygwin is closer to a GNU
+ bash environment such as Linux than to other the other Win32
+ makes.
+
+ Cygwin implements a Posix/Unix runtime system (cygwin1.dll).
+ It is also possible to create Win32 binaries that only use the
+ Microsoft C runtime system (msvcrt.dll or crtdll.dll) using
+ MinGW. MinGW can be used in the Cygwin development environment
+ or in a standalone setup as described in the following section.
+
+ To build OpenSSL using Cygwin:
+
+ * Install Cygwin (see http://cygwin.com/)
- To build OpenSSL, you need the Mingw32 package and GNU make.
+ * Install Perl and ensure it is in the path. Both Cygwin perl
+ (5.6.1-2 or newer) and ActivePerl work.
+
+ * Run the Cygwin bash shell
+
+ * $ tar zxvf openssl-x.x.x.tar.gz
+ $ cd openssl-x.x.x
+
+ To build the Cygwin version of OpenSSL:
+
+ $ ./config
+ [...]
+ $ make
+ [...]
+ $ make test
+ $ make install
+
+ This will create a default install in /usr/local/ssl.
+
+ To build the MinGW version (native Windows) in Cygwin:
+
+ $ ./Configure mingw
+ [...]
+ $ make
+ [...]
+ $ make test
+ $ make install
+
+ Cygwin Notes:
+
+ "make test" and normal file operations may fail in directories
+ mounted as text (i.e. mount -t c:\somewhere /home) due to Cygwin
+ stripping of carriage returns. To avoid this ensure that a binary
+ mount is used, e.g. mount -b c:\somewhere /home.
+
+ "bc" is not provided in older Cygwin distribution. This causes a
+ non-fatal error in "make test" but is otherwise harmless. If
+ desired and needed, GNU bc can be built with Cygwin without change.
+
+ GNU C (MinGW)
+ -------------
* Compiler installation:
- Mingw32 is available from <ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/
- mingw32/egcs-1.1.2/egcs-1.1.2-mingw32.zip>. GNU make is at
- <ftp://agnes.dida.physik.uni-essen.de/home/janjaap/mingw32/binaries/
- make-3.76.1.zip>. Install both of them in C:\egcs-1.1.2 and run
- C:\egcs-1.1.2\mingw32.bat to set the PATH.
+ MinGW is available from http://www.mingw.org. Run the installer and
+ set the MinGW bin directory to the PATH in "System Properties" or
+ autoexec.bat.
* Compile OpenSSL:
- Run ms\mw.bat
+ > ms\mingw32
- This will create the library and binaries in out.
+ This will create the library and binaries in out. In case any problems
+ occur, try
+ > ms\mingw32 no-asm
+ instead.
+ If you want to build a FIPS-certified variant of OpenSSL, add the argument
+ "fips"
libcrypto.a and libssl.a are the static libraries. To use the DLLs,
link with libeay32.a and libssl32.a instead.
> cd out
> ..\ms\test
+
+ Installation
+ ------------
+
+ If you used the Cygwin procedure above, you have already installed and
+ can skip this section. For all other procedures, there's currently no real
+ installation procedure for Win32. There are, however, some suggestions:
+
+ - 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\openssl\* 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
---------------
> perl util\mkdef.pl crypto ssl update
- then ms\do_ms should not give a warning any more. However the numbers that
+ then ms\do_XXX should not give a warning any more. However the numbers that
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
library may need to be recompiled.
- If you get errors about unresolved externals then this means that either you
- didn't read the note above about functions not having numbers assigned or
- someone forgot to add a function to the header file.
+ If you get errors about unresolved symbols there are several possible
+ causes.
- In this latter case check out the header file to see if the function is
- defined in the header file.
+ 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.
One final comment about compiling applications linked to the OpenSSL library.
If you don't use the multithreaded DLL runtime library (/MD option) your
- program will almost certainly crash: see the original SSLeay description
- below for more details.
-
---------------------------------------------------------------------------------
-The orignal Windows build instructions from SSLeay follow.
-Note: some of this may be out of date and no longer applicable. In particular
-the Crypto_malloc_init() comment appears to be wrong: you always need to use
-the same runtime library as the DLL itself.
---------------------------------------------------------------------------------
-
-The Microsoft World.
-
-The good news, to build SSLeay for the Microsft World
-
-Windows 3.1 DLL's
-perl Configure VC-WIN16
-nmake -f ms\w31dll.mak
-
-Windows NT/95 DLL's
-perl Configure VC-WIN32
-nmake -f ms\ntdll.mak
-
-Now the bad news
-All builds were done using Microsofts Visual C++ 1.52c and [45].x.
-If you are a borland person, you are probably going to have to help me
-finish the stuff in util/pl/BC*pl
-
-All builds were made under Windows NT - this means long filenames, so
-you may have problems under Windows 3.1 but probably not under 95.
-
-Because file pointers don't work in DLL's under Windows 3.1 (well at
-least stdin/stdout don't and I don't like having to differentiate
-between these and other file pointers), I now use the BIO file-pointer
-module, which needs to be linked into your application. You can either
-use the memory buffer BIO for IO, or compile bss_file.c into your
-application, it is in the apps directory and is just a copy of
-crypto/buffer/bss_file.c with #define APPS_WIN16 added.
-I have not yet automated the makefile to automatically copy it into 'out'
-for a win 3.1 build....
-
-All callbacks passed into SSLeay for Windows 3.1 need to be of type
-_far _loadds.
-
-I don't support building with the pascal calling convention.
-
-The DLL and static builds are large memory model.
-
-To build static libraries for NT/95 or win 3.1
-
-perl util/mk1mf.pl VC-WIN32 > mf-stat.nt
-perl util/mk1mf.pl VC-WIN16 > mf-stat.w31
-for DLL's
-perl util/mk1mf.pl dll VC-WIN32 > mf-dll.nt
-perl util/mk1mf.pl dll VC-WIN16 > mf-dll.w31
-
-Again you will notice that if you dont have perl, you cannot do this.
-
-Now the next importaint issue. Running Configure!
-I have small assember code files for critical big number library operation
-in crypto/bn/asm. There is, asm code, object files and uuencode
-object files. They are
-x86nt32.asm - 32bit flat memory model assember - suitable Win32
-x86w16.asm - 16bit assember - used in the msdos build.
-x86w32.asm - 32bit assember, win 3.1 segments, used for win16 build.
-
-If you feel compelled to build the 16bit maths routines in the windows 3.1
-build,
-perl Configure VC-W31-16
-perl util/mk1mf.pl dll VC-W31-16 > mf-dll.w31
-
-If you hate assember and don't want anything to do with it,
-perl util/mk1mf.pl no-asm VC-WIN16 > mf-dll.w31
-will work for any of the makefile generations.
-
-There are more options to mk1mf.pl but these all leave the temporary
-files in 'tmp' and the output files in 'out' by default.
-
-The NT build is done for console mode.
-
-The Windows 3.1 version of SSLeay uses quickwin, the interface is ugly
-but it is better than nothing. If you want ugly, try doing anything
-that involves getting a password. I decided to be ugly instead of
-echoing characters. For Windows 3.1 I would just sugest using the
-msdos version of the ssleay application for command line work.
-The QuickWin build is primarily for testing.
-
-For both NT and Windows 3.1, I have not written the code so that
-s_client, s_server can take input from the keyboard. You can happily
-start applications up in separate windows, watch them handshake, and then sit
-there for-ever. I have not had the time to get this working, and I've
-been able to test things from a unix box to the NT box :-).
-Try running ssleay s_server on the windows box
-(with either -cert ../apps/server.pem -www)
-and run ssleay s_time from another window.
-This often stuffs up on Windows 3.1, but I'm not worried since this is
-probably a problem with my demo applications, not the libraries.
-
-After a build of one of the version of microsoft SSLeay,
-'cd ms' and then run 'test'. This should check everything out and
-even does a trial run of generating certificates.
-'test.bat' requires that perl be install, you be in the ms directory
-(not the test directory, thats for unix so stay out :-) and that the
-build output directory be ../out
-
-On a last note, you will probably get division by zero errors and
-stuff after a build. This is due to your own inability to follow
-instructions :-).
-
-The reasons for the problem is probably one of the following.
-
-1) You did not run Configure. This is critical for windows 3.1 when
- using assember. The values in crypto/bn/bn.h must match the
- ones requred for the assember code. (remember that if you
- edit crypto/bn/bn.h by hand, it will be clobered the next time
- you run Configure by the contents of crypto/bn/bn.org).
- SSLeay version -o will list the compile options.
- For VC-WIN32 you need bn(64,32) or bn(32,32)
- For VC-W31-32/VC-WIN16 you need bn(32,32)
- For VC-W31-16 you need bn(32,16) or bn(16,16)
- For VC-MSDOS you need bn(32,16) or bn(16,16).
-
- The first number will be 2 times bigger than the second if
- BN_LLONG is defined in bn.h and the size of the second number
- depends on the 'bits' defined at the start of bn.h. Have a
- look, it's all reasonably clear.
- If you want to start messing with 8 bit builds and things like
- that, build without the assember by re-generating a makefile
- via 'perl util/mk1mf.pl no-asm'.
-2) You tried to build under MS-DOS or Windows 3.1 using the /G3
- option. Don't. It is buggy (thats why you just got that
- error) and unless you want to work out which optimising flag
- to turn off, I'm not going to help you :-). I also noticed
- that code often ran slower when compiled with /G3.
-3) Under NT/95, malloc goes stupid. You are probably linking with
- the wrong library, there are problems if you mix the threaded
- and non-threaded libraries (due to the DLL being staticly
- linked with one and the applicaion using another.
-
-Well hopefully thats most of the MS issues handled, see you in ssl-users :-).

-
-SSLeay 0.6.5
-For Windows 95/NT, add CRYPTO_malloc_init() to your program before any
-calls to the SSLeay libraries. This function will insert callbacks so that
-the SSLeay libraries will use the same malloc(), free() and realloc() as
-your application so 'problem 3)' mentioned above will go away.
-
-There is now DES assember for Windows NT/95. The file is
-crypto/des/asm/win32.asm and replaces crypto/des/des_enc.c in the build.
-
-There is also Blowfish assember for Windows NT/95. The file is
-crypto/bf/asm/win32.asm and replaces crypto/bf/bf_enc.c in the build.

+ 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
+ rely on CRYPTO_malloc_init() solving your problem, and you should
+ consistently use the multithreaded library.
