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. + + and one of the following C compilers: + + * Visual C++ + * Borland C + * 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 + get it all to work. See the trouble shooting section later on for if (when?) + it goes wrong. + + Visual C++ + ---------- + + 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: + + > perl Configure VC-WIN32 --prefix=c:/some/openssl/dir + +Where the prefix argument specifies where OpenSSL will be installed to. + + 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: + + > nmake -f ms\ntdll.mak test + + +To install OpenSSL to the specified location do: + +> nmake -f ms\ntdll.mak install + + 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. + + + By default in 0.9.8 OpenSSL will compile builtin ENGINES into the libeay32.dll + shared library. If you specify the "no-static-engine" option on the command + line to Configure the shared library build (ms\ntdll.mak) will compile the + engines as separate DLLs. + + 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 (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/) + + * 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: + + 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: + + > 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 + + + 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 + --------------- + + 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. + + Linking your application + ------------------------ + + If you link with static OpenSSL libraries [those built with ms/nt.mak], + then you're expected to additionally link your application with + WSOCK32.LIB, ADVAPI32.LIB, GDI32.LIB and USER32.LIB. Those developing + non-interactive service applications might feel concerned about linking + with latter two, as they are justly associated with interactive desktop, + which is not available to service processes. The toolkit is designed + to detect in which context it's currently executed, GUI, console app + or service, and act accordingly, namely whether or not to actually make + GUI calls. + + If you link with OpenSSL .DLLs, then you're expected to include into + your application code small "shim" snippet, which provides glue between + OpenSSL BIO layer and your compiler run-time.
