问题
[Update] I've since compiled successfully and anyone else chasing these binaries can download from here
I'm compiling version 2.06 of lzo by issuing the following command from the Visual Studio Command Prompt (2010)
b\win64\vc_dll.bat
which produces lzo2.dll without any errors, however this doesnt look like it really did produce the 64-bit dll as my 32bit C# app can still reference and call methods (successfully)
How can I compile the 64bit version?
some of the comments on this question may be outdated as the question changed but I since changed it back to the original question when it got more involved so I could mark the response as the answer
回答1:
Almost certainly you will be using the wrong set of compilers; 64bit compilation isn't controlled by a command line flag - it's a completely different toolset;
Issue the build commands from the "Visual Studio x64 Win64 Command Prompt (2010)" which you will find in the Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools.
e.g.
c:\> cd /d h:\temp\lzo-2.06
H:\temp\lzo-2.06> b\win64\vc_dll.bat
