32bit-64bit

问题 We are working on converting a set .net applications to 64-bit from the original 32-bit. We have the code of the application. So we are recompiling the application with the any-CPU setting. We had so far issues with Oracle's data access components. For that, we set the reference as copy local = false and specific version = false . As these assemblies are installed in GAC, in the target machine, the reference is automatically set to the correct 64-bit version from the GAC (we install the

I need to use this code in PHP, independently from integer size (the above code works up to 128-bit integers,

问题 Not sure this has been asked before (I could not find any). I have simple console app/ESE and have the below settings. I'm running Windows 8, 63bit OS. And the EXE target framework .NET 4.5 However, when I compile this EXE, it still shows as a 32bit EXE. Since this is "Any CPU", I would expect the EXE to compile as 64bit / PE32+. Can some please help tell why this would be still 32bit? 回答1: You are misinterpreting CorFlags I think. Here is a CorFlags truth table: CPU Architecture PE 32BITREQ

问题 I am currently using Windows on my default development system and Linux on my server where I deploy my Lua scripts. For Windows there are only several 32 bit interpreters like Lua for Windows one I currently use (at least as far as i know). On the server the interpreter is running the scripts on 64 bits. Now my question is: Is it possible to check on which architecture the script is running (probably similar to the _ENV variable for the version)? If there is any 64 bit Windows Lua interpreter

问题 I am writing an app in swift that saves its data through apple's core data. In my code, all integers are just declared as "Int", because that is more flexible and the compiler adapts those ints to the device the code runs on. However, when I want to save these "Int"s using core data, I have to chose either 32 or 64 bit Integers. I would want my app to be compatible with iphone 5-6s if possible and am therefore hesitant to go for the 32bit(I read Apple moved to 32bit in 6s because of better

问题 Here's my scenario: the company I work has applications deployed to a 32bit Windows 2003 server and they want to move to a Windows 2008 Server that is 64 bit. It has been noted that these 32bit custom developed applications will not run on a 64 bit machine. I was not aware of this. I have always thought that 32bit software CAN run on a 64 bit OS and just use the 32bit address. A 64 bit software on the other cannot run on a 32 bit OS. On a 64 bit, one does have to create 64 bit software but

问题 I have received this error after updating to Windows 7 64-bit and then running an existing .NET Website. [InvalidOperationException: Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.] I have only installed the 32-bit Oracle Client installed and I understand that on my 64-bit development machine the application is expecting 64-bit libraries UNLESS explicitly stated. This

问题 After successfully testing my MVC4 programs using this environment I tried to publish it to 64-bit Windows 2008 Server with the IIS that disallows 32 bit apps, then I start getting stuck with the exception : the referenced dll's dependencies cannot be found! I tried every advice the internet can give me including modifying web.config to reflect their dlls' on deploy-to server win 2008 using global cache cmd's on the prompt! Yet nothing works. 32-bit is working but 64-bit is flat broke! 回答1:

问题 For those looking for the answer, there it's, as it's not clear on other websites. This is required at least by the Intel compiler. Maybe it helps also for other software. 回答1: Just run those commands in your terminal. sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install build-essential gcc-multilib rpm libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386 Or as root remove the "sudo" from them. 来源： https://stackoverflow.com/questions/30236342/debian-stretch-and

问题 I have a 64 bit Enterprice SuSE 11 I have an application which open a HIDRAW device and operate an ioctl function on it to get raw info from this device like below: struct hidraw_devinfo devinfo; int fd = open("/dev/hidraw0", 0); int ret = ioctl(fd, HIDIOCGRAWINFO, &devinfo); ... If I compile this program in 64 bit mode there is no error and no problem and when I execute the application the ioctl function works properly. g++ main.cpp If I complie this program in 32 bit mode there is also no
