- NOTES FOR THE WINDOWS PLATFORMS
- ===============================
-
- [Notes for Windows CE can be found in INSTALL.WCE]
-
- Requirement details for native (Visual C++) builds
- --------------------------------------------------
-
- - You need Perl. We recommend ActiveState Perl, available from
- http://www.activestate.com/ActivePerl.
- You also need the perl module Text::Template, available on CPAN.
- Please read README.PERL for more information.
-
- - You need a C compiler. OpenSSL has been tested to build with these:
-
- * Visual C++
-
- - Netwide Assembler, a.k.a. NASM, available from http://www.nasm.us,
- is required if you intend to utilize assembler modules. Note that NASM
- is the only supported assembler. The Microsoft provided assembler is NOT
- supported.
-
-
- GNU C (Cygwin)
- --------------
-
- Cygwin implements a Posix/Unix runtime system (cygwin1.dll) on top of the
- Windows subsystem and provides a bash shell and GNU tools environment.
- Consequently, a make of OpenSSL with Cygwin is virtually identical to the
- Unix procedure.
-
- To build OpenSSL using Cygwin, you need to:
-
- * Install Cygwin (see http://cygwin.com/)
-
- * Install Cygwin Perl and ensure it is in the path. Recall that
- as least 5.10.0 is required.
-
- * Run the Cygwin bash shell
-
- Apart from that, follow the Unix instructions in INSTALL.
-
- NOTE: "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.
-
- It is also possible to create "conventional" Windows binaries that use
- the Microsoft C runtime system (msvcrt.dll or crtdll.dll) using MinGW
- development add-on for Cygwin. MinGW is supported even as a standalone
- setup as described in the following section. In the context you should
- recognize that binaries targeting Cygwin itself are not interchangeable
- with "conventional" Windows binaries you generate with/for MinGW.
-
- GNU C (MinGW/MSYS)
- -------------
-
- * Compiler and shell environment installation:
-
- MinGW and MSYS are available from http://www.mingw.org/, both are
- required. Run the installers and do whatever magic they say it takes
- to start MSYS bash shell with GNU tools and matching Perl on its PATH.
- "Matching Perl" refers to chosen "shell environment", i.e. if built
- under MSYS, then Perl compiled for MSYS is highly recommended.
-
- Alternativelly, one can use MSYS2 from http://msys2.github.io/,
- which includes MingW (32-bit and 64-bit).
-
- * It is also possible to cross-compile it on Linux by configuring
- with './Configure --cross-compile-prefix=i386-mingw32- mingw ...'.
- Other possible cross compile prefixes include x86_64-w64-mingw32-
- and i686-w64-mingw32-.
-
-
- "Classic" builds (Visual C++)
- ----------------
-
- [OpenSSL was classically built using a script called mk1mf. This is
- still available by configuring with --classic. The notes below are
- using this flag, and are tentative. Use with care.
-
- NOTE: this won't be available for long.]
-
- If you want to compile in the assembly language routines with Visual
- C++, then you will need the Netwide Assembler binary, nasmw.exe or nasm.exe, to
- be available on your %PATH%.
-
- Firstly you should run Configure and generate the Makefiles. If you don't want
- the assembly language files then add the "no-asm" option (without quotes) to
- the Configure lines below.
-
- For Win32:
-
- > perl Configure VC-WIN32 --classic --prefix=c:\some\openssl\dir
- > ms\do_nasm
-
- Note: replace the last line above with the following if not using the assembly
- language files:
-
- > ms\do_ms
-
- For Win64/x64:
-
- > perl Configure VC-WIN64A --classic --prefix=c:\some\openssl\dir
- > ms\do_win64a
-
- For Win64/IA64:
-
- > perl Configure VC-WIN64I --classic --prefix=c:\some\openssl\dir
- > ms\do_win64i
-
- Where the prefix argument specifies where OpenSSL will be installed to.
-
- Then from the VC++ environment at a prompt do the following. Note, your %PATH%
- and other environment variables should be set up for 32-bit or 64-bit
- development as appropriate.
-
- > 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 Windows compile
- environment. By default the library is not compiled with debugging
- symbols. If you add --debug to the Configure lines above then debugging symbols
- will be compiled in.
-
- By default in 1.1.0 OpenSSL will compile builtin ENGINES into separate shared
- libraries. If you specify the "enable-static-engine" option on the command line
- to Configure the shared library build (ms\ntdll.mak) will compile the engines
- into libcrypto32.dll instead.
-
- You can also build a static version of the library using the Makefile
- ms\nt.mak
-
- Linking your application
- ------------------------
-
- This section applies to non-Cygwin builds.
-
- If you link with static OpenSSL libraries then you're expected to
- additionally link your application with WS2_32.LIB, ADVAPI32.LIB,
- GDI32.LIB and USER32.LIB. Those developing non-interactive service
- applications might feel concerned about linking with the 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.
- Additionally those who wish to /DELAYLOAD:GDI32.DLL and /DELAYLOAD:USER32.DLL
- and actually keep them off service process should consider
- implementing and exporting from .exe image in question own
- _OPENSSL_isservice not relying on USER32.DLL.
- E.g., on Windows Vista and later you could:
-
- __declspec(dllexport) __cdecl BOOL _OPENSSL_isservice(void)
- { DWORD sess;
- if (ProcessIdToSessionId(GetCurrentProcessId(),&sess))
- return sess==0;
- return FALSE;
- }
-
- 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. See the OPENSSL_Applink
- manual page for further details.
