One thing to check is if you do a 32-bit build first, then a 64-bit build. OpenSSL unfortunately does not support a "parallel build tree" as well as other libraries. For non-Windows, there's a script that will create a sibling directory, and then make soft links for all the files.
What I end up doing for all the platforms is just having a complete copy of the tree for a given target at build-time (i.e., Windows-Win32, Windows-x64, MacOSX-x64, etc.). For Windows, I also make some customizations to ms\ntdll.mak after the perl configure and do_win64a.bat, and before nmake. I also reference my own build of zlib for Windows. Here's the script I use (Build-Windows-x64.bat). You can take out the things that don't apply. This will open ms\ntdll.mak in notepad, so you can make some tweaks, then once you save and close Notepad, it will go on. --------------------------------- :: NOTE: Make sure: :: 1. Perl (ActivePerl from ActiveState) is installed, and is in the path :: OLD 2: Note that VS 2010 has "ml" (and ml64), so we don't need MASM itself to run the "do_masm.bat" :: NEW 2: OpenSSL on Windows wants NASM (nasm.sourceforge.net). Install that and put it in the path. :: 3. Paths need to be "backwards" for windows, because they are used when buliding up C++ code, as well as in other places. :: (c:/my/path instead of c:\my\path) :: 4. For debug configuration, copy do_nasm and friends and make "_debug" version - find "mk1mf.pl", and add "debug" before VC-WIN32 :: 5. Be sure to run this under a "VS 2010 x64 Command Line". :: 6. For the x64 build, there's trouble getting it to compile on Windows Server 2010 x64. :: On 32-bit XP (with DXSDK and Windows SDK installed), it gets farther, but ran into :: link error with bufferoverflowu.lib. That turned out to be a PSDK library (to support /GS), :: and it looks like it wasn't found in any of the LIB paths. There was one LIB path that :: wasn't in the list. So, before running any of this, update the LIB path: :: set LIB=%LIB%;C:\Program Files\Microsoft Visual Studio 10\VC\PlatformSDK\Lib\AMD64 :: 7.

I hope someone will be able to help/advise. Following the instructions in INSTALL.W32 seems to work for 32 bit release mode but not for other combinations. Switching from Release to Debug does not result in the pdb files being installed via the command nmake -f ms\ntdll.mak install. I tried to build in 64 bit by running vcvarsall amd64 then following the build steps. The compilations were successful, with a few warnings about conversions, but I got a linktime error: rc /fo"tmp32dll\libeay32.res" /d CRYPTO ms\version32.rc link /nologo /subsystem:console /opt:ref /debug /dll /out:out32dll\libeay32.dll /def:ms/LIBEAY32.def @C:\Users\marlowa\AppData\Local\Temp\nmEFE4.tmp mp32dll\x86cpuid.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64' MAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 8\VC\BIN\amd64\link.EXE"' : return code '0x458' Stop. I am on windows 7 (64 bit) using the Visual Studio 2005 compiler. Googling, I see that others have hit this problem as well: http://comments.gmane.org/gmane.comp.encryption.openssl.devel/16256 http://stackoverflow.com/questions/2559358/fatal-error-lnk1112-module-machin e-type-x86-conflicts-with-target-machine-typ http://stackoverflow.com/questions/14704592/fatal-error-lnk1112-module-machi ne-type-x86-conflicts-with-target-machine-typ It looks to me like the 64 bit build is using some components that came out of the 32 bit build, but I am not sure.
