INSTALLATION ON THE WIN32 PLATFORM
|
||||
----------------------------------
|
||||
|
||||
[Instructions for building for Windows CE can be found in INSTALL.WCE]
|
||||
|
||||
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.
|
||||
For Cygwin users, there's more info in the Cygwin section.
|
||||
|
||||
and one of the following C compilers:
|
||||
|
||||
* Visual C++
|
||||
* Borland C
|
||||
* 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.
|
||||
|
||||
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.
|
||||
|
||||
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.
|
||||
|
||||
Visual C++
|
||||
----------
|
||||
|
||||
Firstly you should run Configure:
|
||||
|
||||
> perl Configure VC-WIN32
|
||||
|
||||
Next you need to build the Makefiles and optionally the assembly language
|
||||
files:
|
||||
|
||||
- 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 won't be able to compile it as it
|
||||
stands.
|
||||
|
||||
Then from the VC++ environment at a prompt do:
|
||||
|
||||
> nmake -f ms\ntdll.mak
|
||||
|
||||
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
|
||||
|
||||
Tweaks:
|
||||
|
||||
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.
|
||||
|
||||
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 5
|
||||
---------------------
|
||||
|
||||
* Configure for building with Borland Builder:
|
||||
> perl Configure BC-32
|
||||
|
||||
* Create the appropriate makefile
|
||||
> ms\do_nasm
|
||||
|
||||
* Build
|
||||
> make -f ms\bcb.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.
|
||||
|
||||
* Compiler installation:
|
||||
|
||||
Mingw32 is available from <ftp://ftp.xraylith.wisc.edu/pub/khan/
|
||||
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.
|
||||
|
||||
* Compile OpenSSL:
|
||||
|
||||
> ms\mingw32
|
||||
|
||||
This will create the library and binaries in out. In case any problems
|
||||
occur, try
|
||||
> ms\mingw32 no-asm
|
||||
instead.
|
||||
|
||||
libcrypto.a and libssl.a are the static libraries. To use the DLLs,
|
||||
link with libeay32.a and libssl32.a instead.
|
||||
|
||||
See troubleshooting if you get error messages about functions not having
|
||||
a number assigned.
|
||||
|
||||
* You can now try the tests:
|
||||
|
||||
> cd out
|
||||
> ..\ms\test
|
||||
|
||||
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 W32 makes which are
|
||||
based on a single makefile approach. Cygwin implements Posix/Unix
|
||||
calls through cygwin1.dll, and is contrasted to Mingw32 which links
|
||||
dynamically to msvcrt.dll or crtdll.dll.
|
||||
|
||||
To build OpenSSL using Cygwin:
|
||||
|
||||
* Install Cygwin (see http://cygwin.com/)
|
||||
|
||||
* 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
|
||||
ActivePerl)
|
||||
|
||||
* Run the Cygwin bash shell
|
||||
|
||||
* $ tar zxvf openssl-x.x.x.tar.gz
|
||||
$ cd openssl-x.x.x
|
||||
$ ./config
|
||||
[...]
|
||||
$ make
|
||||
[...]
|
||||
$ make test
|
||||
$ make install
|
||||
|
||||
This will create a default install in /usr/local/ssl.
|
||||
|
||||
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.
|
||||
|
||||
|
||||
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\* 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
|
||||
---------------
|
||||
|
||||
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:
|
||||
|
||||
> perl util\mkdef.pl crypto ssl update
|
||||
|
||||
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 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
|
||||
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.
|
||||
|
||||
INSTALLATION ON THE WIN32 PLATFORM
|
||||
----------------------------------
|

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
|
||||
---------------
|
||||
|
||||
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:
|
||||
|
||||
> perl util\mkdef.pl crypto ssl update
|
||||
|
||||
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 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
|
||||
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.
