Andy,
Thanks for explanation. As answer on your question whether ml64.exe is existent: when setting Visual Studio 2010 (SP1) x64 command line environment, ml64.exe is accessible via the path (in c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\ml64.exe). Microsoft has already dropped support for Visual Studio 2005. It is quite safe/reasonable to put the minimum required VS version to e.g. 2008 (with latest SPs). But that's just my opinion. We (=our department) is just busy moving away from VS2005... Note my other reply, since I got openSSL buildable/working for x64 too (with VS 2010 SP1).

It has nothing to do with performance, but with so called OPENSSL_Applink. In 32-bit build it's managed without assembler module thanks to inline assembler support in compiler, which is not an option for 64-bit compilers.

Strange. In order to fail both nasm and ml64 should be absent... While Microsoft failed to include assembler with initial Visual x64-capable release, as far as I understand it was present on later releases (and was available as separate download for initial release). Don't you have ml64? > Is it possible to make some more generic batch files? I'll give it a thought... ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [email protected] Automated List Manager [email protected]
