64-bit

问题 I'm trying to install opencv and use it with xCode for making application in C++. I installed it using macports and follow many tutorials to do it. I have done the linking too in xcode but there is problems that some function dosen't work. it give an error like Undefined symbols for architecture x86_64: cv::resize(cv::_InputArray const&, cv::_OutputArray const&, cv::Size_<int>, double, double, int)", "cv::floodFill(cv::_OutputArray const&, cv::Point_<int>, cv::Scalar_<double>, cv::Rect_<int>*

问题 Does {$SetPEFlags IMAGE_FILE_LARGE_ADDRESS_AWARE} have any effects on 64-bit delphi applications? 回答1: It has no effect at all. All 64 bit processes are automatically decreed to be large address aware. 来源： https://stackoverflow.com/questions/15510715/setpeflags-image-file-large-address-aware-in-64-bit-delphi-application

问题 java.sql.SQLException: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application I get the following error when I try to connect to my Microsoft Access database from an eclipse project using jdbc. I am using 64bit windows and microsoft office 2007. any help on this matter would be great. 回答1: Access 2010 has 64 bit drivers and can be downloaded http://www.microsoft.com/downloads/details.aspx?FamilyID=C06B8369-60DD-4B64-A44B

问题 I have a strongly recursive function, that creates a (very small) std::multimap locally for each function instance using new (which recurses to malloc/calloc in the std lib). After some hundred recursions new fails although i am using a native 64Bit application on Windows XP x64. The machine has 10 GB RAM, The application only uses about 1GB. No other big apps are running. This happens a few minutes after starting the program and starting the recursive function. The recursive function has

问题 I need a common rule for warnings in x64 mode. Which way is better? Consider the following lines of some code const int N = std::max_element(cont.begin(), cont.end()) - cont.begin(); or const int ARR_SIZE = 1024; char arr[ARR_SIZE]; //... const int N = std::max_element(arr, arr + ARR_SIZE) - arr; It is my usual code. I have no problems with x86. But if I run compiler in x64 mode I have some warnings: conversion from 'std::_Array_iterator<_Ty,_Size>::difference_type' to 'int', possible loss of

问题 I have recently migrated from a 32bit environment to a 64bit one, and it has gone smoothly apart from one problem: glMultiDrawElements uses some arrays that do not work without some tweaking under a 64bit OS. glMultiDrawElements( GL_LINE_LOOP, fCount_, GL_UNSIGNED_INT, reinterpret_cast< const GLvoid** >( iOffset_ ), mesh().faces().size() ); I am using VBOs for both the vertices and vertex indices. fCount_ and iOffset_ are arrays of GLsizei . Since a buffer is bound to GL_ELEMENT_ARRAY_BUFFER

问题 Whenever I try to open camera/gallery through intent, I am getting this error in my Honor 4C mobile, Android version 6.0 with 64-bit octa-core CPU. load: so=/system/lib64/libhwuibp.so dlopen failed: library "/system/lib64/libhwuibp.so" not found Basically I am trying to crop an image with help of OpenCV-2.4.13.1-android-sdk so file. But this error seems to be device related as in other mobiles the app is working totally fine, could anyone help me in this? 回答1: Have you tried this solution? Hi

问题 Before, when I was using win32, I used FreeImage in order to load and save bitmaps of bit depth greater than 8 bits. That's every image I work with, since I'm doing medical imaging, and before anyone says anything, yes, me and my customers have spent a lot of money on high-brightness, high-contrast monitors with 11 or 12 bits of dynamic range. In fact, if you're curious, requirements by the ACR for running mammography incldue a monitor with at least 10 bits of dynamic range. I just switched

问题 I frequently use the sendsignal tool for WebSphere Application Server processes (server, launchClient, wsadmin, etc.) in order to generate heap dumps. However, sendsignal doesn't work on 64-bit machines. Does anyone know of an alternative for sending the ctrl-break to a remote process? Update: Bengt points out that this is basically the same as the following question. So, I guess my question is: has anyone found a way around this limitation in the past two years? Can I send a ctrl-C (SIGINT)

问题 We are developing a swing application written by Java which requires only about 128MB memory, and in the short future I don't see it will require much more memory like 4GB. Previously we provide always 3 different releases, one for 32-bit Windows, one for 32-bit Linux and another for 64-bit Linux, with an installer which has JRE included. The 64-bit version was not used by anyone until couple of weeks ago, and an OutOfMemoryException was reported because the application consumes about 40-50%
