64-bit

问题 I am working on Windows client application using c#, have two projects in my VS 2010 solution, the start-up project and a class library which uses third party COM interop DLL.My desktop is 64 bit and all the client machines are 64 bit as well. If I keep the start-up project as any cpu in (build settings) and x86 for the second project which invokes the COM DLL, I am getting the following error: Could not load file or assembly ... or one of its dependencies. An attempt was made load a program

问题 I'm trying to port some inline assembly code written in Visual Studio into MASM64. The original code uses _emit which is a pseudo instruction that defines one byte at the current location in the current text segment. How would I do the same in x64 assembly MASM? 回答1: You can just use db , as in: db 10h You do this most often in a data segment, unless things have changed in the 64-bit version of MASM, it should work in the code segment as well. 来源： https://stackoverflow.com/questions/6916050

问题 I created a new c++ project in VS2010. I added x64 as a new solution platform. I tried setting "copy settings from" to both "Win32" and "empty", but neither worked. _AMD64_ is not defined when I select x64 as the platform. Shouldn't it be? Is there another step I am unaware of for compiling for 64 bit? In anticipation to questions: I am using VS2010 Ultimate, Windows 7 64bit, x64 compilers were selected during VS installation. 回答1: You've got all the steps right. An _AMD64_ symbol is not

问题 I have a Unity project that I'm switching from APKs to AABs (app bundles). Previously, when I was building it as an APK, the Google Play Console told me the APK was 64-bit compliant. Now that I'm building an aab, I'm getting the warning: This release is not compliant with the Google Play 64-bit requirement. The following APKs or App Bundles are available to 64-bit devices, but they only have 32-bit native code I have both ARM7 and ARM64 architectures set. I am excluding x86. When I open the

问题 I am trying to compile the Qt library (I don't need the demos or examples) for 64-bit Windows. There are instructions here but I run into the error described in the comment below it. There doesn't seem to be a reference anywhere for how one might go about doing this process. I am targetting Microsoft Visual C++ 2010 Express. It looks like I need Perl and the Windows SDK as well - how do I go about this process? 回答1: This process is quite tedious and time-consuming - but I will explain each

问题 I am trying to develop an application which detects if program is running inside a virtual machine. For 32-bit Windows, there are already methods explained in the following link: http://www.codeproject.com/Articles/9823/Detect-if-your-program-is-running-inside-a-Virtual I am trying to adapt the code regarding Virtual PC and VMware detection in an 64-bit Windows operating system. For VMware, the code can detect successfully in an Windows XP 64-bit OS. But the program crashes when I run it in a

问题 I have changed the gradle to something like this, which is in accordance with the documentation from Google Dev. then how do I know if my application supports 64 bits? I tried with Build -> Analyze APK, but I did not find the lib folder or file with the format .so. how to solved this? 回答1: The 64 bit change only affects apps that use "native code", ie code that compiles for the processor on the device, as opposed to being written in Java or Kotlin. This will only be true for you if: You have

问题 I'am using zbar in my application. If I want to run it on my iPhone 5s with an 64 bit processor, I get the following errors: Is it possible to use the 32 bit library on a 64 bit device, because I don't think, the library is going to be updated. 回答1: To summarize the comments above. A 64bit iPhone application requires all constituent libraries and frameworks to be 64bit. You can't mix and match. Leaving an application 32bit is non-optimal long term since iOS has to keep two versions of the

问题 Is there any way to run a MIPS binary on a Linux x86/x86-x64 machine? I got some applications for Enigma2 set-top-boxes (which is also based on Linux) that I want to run on a x86/x86-64 machine. These plugins are only available for MIPS processors. 回答1: The keyword is "emulator". The most famous emulator is qemu which can pretty much emulate any architectures out there, but there are also lots of MIPS emulators on Linux that you can find in the Linux-MIPS wiki: Open Virtual Platforms (OVP)
