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. See the end of this file for Eric's original comments.
+ modification.
You need Perl for Win32 (available from http://www.activestate.com/ActivePerl)
and one of the following C compilers:
* Microsoft MASM (aka "ml")
* Free Netwide Assembler NASM.
- MASM was I believe distributed in the past with VC++ and it is also part of
- the MSDN SDKs. It is no longer distributed as part of VC++ and can be hard
- to get hold of. It can be purchased: see Microsoft's site for details at:
- http://www.microsoft.com/
+ MASM was at one point distributed with VC++. It is now 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:
> ms\do_ms
If you get errors about things not having numbers assigned then check the

libcrypto.a and libssl.a are the static libraries. To use the DLLs,
link with libeay32.a and libssl32.a instead.

+ GNU C (CygWin32)
+ ---------------
+
+ CygWin32 provides a bash shell and GNU tools environment running on
+ NT 4.0, Windows 9x and Windows 2000. Consequently, a make of OpenSSL
+ with CygWin is closer to a GNU bash environment such as Linux rather
+ than other W32 makes that are based on a single makefile approach.
+ CygWin32 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 CygWin32:
+
+ * Install CygWin32 (see http://sourceware.cygnus.com/cygwin)
+
+ * Install Perl and ensure it is in the path
+
+ * Run the CygWin bash shell
+
+ * $ tar zxvf openssl-x.x.x.tar.gz
+ $ cd openssl-x.x.x
+ $ ./Configure no-threads CygWin32
+ [...]
+ $ make
+ [...]
+ $ make test
+ $ make install
+
+ This will create a default install in /usr/local/ssl.
+
+ CygWin32 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.
+
+ As of version 1.1.1 CygWin32 is relatively unstable in its handling
+ of cr/lf issues. These make procedures succeeded with versions 1.1 and
+ the snapshot 20000524 (Slow!).
+
+ "bc" is not provided in the CygWin32 distribution. This causes a
+ non-fatal error in "make test" but is otherwise harmless. If
+ desired, GNU bc can be built with CygWin32 without change.
+
+
+ Installation
+ ------------
+
+ 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
---------------
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.
+
+ 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.
- In this latter case check out the header file to see if the function is
- defined in the header file.
+ 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.
