64-bit

问题 I was recently able to build Apache Hadoop 2.5.1 with native 64 bit support. So, I got rid of the annoying Native Libraries Warning. I'm trying to configure Apache Spark. When I start spark-shell, the same warning appears: 14/09/14 18:48:42 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable Some tips: I had to download a pre-built 2.4 version of Spark because there is still no profile for Hadoop 2.5 with Maven. The

问题 It seems like people are compiling MRI Ruby (1.8.7) for 64-bit platforms. I've been searching and reading for a while now without really getting the answers I want. What I want to know is if any of you guys actually used more than 4GB of memory in Ruby? Is Ruby truly 64-bits if you compile it that way? I've found comments in the source code indicating that it's not tested on 64-bits. For instance it says "BigDecimal has not yet been compiled and tested on 64 bit integer system." in the

问题 it works on 32-bit platform.but not 64-bit here is the exzample TVerbInfo = packed record Verb: Smallint; Flags: Word; end; var VerbInfo: TVerbInfo; strList : TStringList; verb : Smallint; flags : Word; begin strList := TStringList.create(); ..... verbInfo.verb := verb; verbInfo.flags := flags; strList.addObject('verb1',TObject(VerbInfo)); //invalid typecast happened here end; can anyone help me? thank you very much 回答1: You can try something like this: function MakeVerbInfoObject(const

问题 I'm trying to use the WMI example from msdn: http://msdn.microsoft.com/en-us/library/windows/desktop/aa384724%28v=vs.85%29.aspx I've copied the last set of code there verbatim into a console application in VS2008. If I have the application in release or debug for the win32 platform, it compiles (and runs) fine. If I have it in release or debug for the x64 platform, I get the following linker errors: CppConsole.obj : error LNK2001: unresolved external symbol IID_IWbemConfigureRefresher

问题 How can I determine if I'm running on a 32bit or a 64bit version of matlab? I have some pre-compiled mex-files which need different path's depending on 32/64bit matlab. 回答1: The question of 32 vs. 64 bits is really a red herring. If I understand correctly, you want to determine which set of compiled MEX files are needed so you can set the path appropriately. For this, you can use the function mexext : >> help mexext MEXEXT MEX filename extension for this platform, or all platforms. EXT =

问题 I'm writing a C# Azure function via Visual Studio. This function is triggered through blog storage, and the blob is processed using an x64 C++ DLL. The issue is that the default Azure functions tooling installed with visual studio only has an x86 version of the functions exe (func.exe). I see at this URL, there are now x64 builds: https://github.com/Azure/azure-functions-core-tools/releases The problem is, by default, Visual Studio is picking version 1.2.0 of the tools on my machine (C:\Users

问题 Does a application in .NET need to be built in 64 bit to take full advantage of a machine with a 64 bit OS on it, or will it take advantage of it just as a 32 bit build. Basically, we have an issue with an out of memory exception and it was suggested to run the console app on a 64 bit box which "may" solve the issue. The question is can we just spin up a 64 box and throw the current app on it or do I need to rebuild the app in a 64 bit way. 回答1: If your app is configured to build for the "Any

I recently upgraded to a 64 bit computer from a 32 bit. I have used masm32 for x86 assembly previously. My computer can run 32 bit processes, but I would prefer to use all of my computers capability and write x64 assembly programs. I do not want to have to install extra things (like ide's) to make an assembler
