I'm using boost 1.47 for Arm, with the Code Sourcery C++ compiler (4.5.1), crosscompiling from Windows 7 targeting Ubuntu. When we compile the debug version (ie asserts are enabled), there is an assert triggered: pthread_mutex_lock.c:62: __pthread_mutex_lock: Assertion 'mutex->__data.__owner == 0' failed. Compiling in release mode, the assert is not triggered and the program works fine
我使用Code Sourcery C ++编译器（4.5.1）针对Arm使用boost 1.47，从针对Ubuntu的Windows 7进行交叉编译。 当我们编译调试版本（即断言被启用）时，会触发一个断言： pthread_mutex_lock.c:62: __pthread_mutex_lock: Assertion 'mutex->__data.__owner == 0' failed. 在释放模式下编译，断言不会被触发，程序也能正常工作（据我们所知）。 这是在Ubuntu 10.x手臂板下发生的。 所以，似乎pthread_mutex_lock认为互斥
I am about to debug something within my boost asio socket communication. And found this piece of code inside of the asio library (found in boost/asio/impl/write.hpp line 169 (boost 1.47) ): switch (start) { case 1: buffers_.prepare(this->check_for_completion(ec, total_transferred_)); for (;;) { stream_.async_write_some(buffers_, BOOST_ASIO_MOVE_CAST(write_
我即将在我的boost asio套接字通信中进行调试。 并在asio库中找到这段代码（在boost / asio / impl / write.hpp第169行（boost 1.47）中找到）： switch (start) { case 1: buffers_.prepare(this->check_for_completion(ec, total_transferred_)); for (;;) { stream_.async_write_some(buffers_, BOOST_ASIO_MOVE_CAST(write_op)(*this)); return; default: total_t
I'm running the following code, using Visual Studio 2008 SP1, on Windows Vista Business x64, quad core machine, 8gb ram. If I build a release build, and run it from the command line, it reports 31ms. If I then start it from the IDE, using F5, it reports 23353ms. Here are the times: (all Win32 builds) DEBUG, command line: 421ms DEBUG, from the IDE: 24,570ms RELEASE, command line: 31
我正在使用Visual Studio 2008 SP1在Windows Vista Business x64，四核机器，8GB RAM上运行以下代码。 如果我构建了一个发布版本，并从命令行运行它，它会报告31ms。 如果我使用F5从IDE启动它，则报告23353ms。 这里是时代：（所有的Win32版本） DEBUG，命令行：421ms DEBUG，来自IDE：24,570ms RELEASE，命令行：31ms RELEASE，来自IDE：23,353ms 码： #include <windows.h> #include <iostream> #
I've got a "Schroedinger's Cat" type of problem here -- my program (actually the test suite for my program, but a program nonetheless) is crashing, but only when built in release mode, and only when launched from the command line. Through caveman debugging (ie, nasty printf() messages all over the place), I have determined the test method where the code is crashing, though unfo
我在这里遇到了一个“Schroedinger's Cat”类型的问题 - 我的程序（实际上是我的程序的测试套件，但是程序仍在运行）正在崩溃，但是只有在发布模式下构建时，只有在从命令行启动时。 通过洞穴调试（即，讨厌的printf（）消息到处），我已经确定了代码崩溃的测试方法，但不幸的是实际崩溃似乎发生在某个析构函数中，因为我看到的最后一条跟踪消息是干净地执行的其他析构函数。 当我尝试在Visual Studio中运行此程序时，它不
I need a way to put various items into sets. Each item can be in only 1 set at a time. I also need to be able to ask the item which set it is in. I have 3 questions: Is this a valid implementation? How can I use this if I split the classes into multiple header files, because each class requires the other? Can I use a reference instead of the pointer to Manager in item class (because I don
我需要一种方法来将各种物品放入集合中。 每个项目一次只能设置一个。 我还需要能够询问它所设置的项目。我有3个问题： 这是一个有效的实现？ 如果我将这些类拆分为多个头文件，我该如何使用它，因为每个类都需要另一个类？ 我可以在项目类中使用引用而不是指向Manager的指针（因为我不喜欢指针）？ class Manager { public: add_item(Item& item) { items.insert(&item); item.manager = this; }

What I'm trying to do is measure the thickness of the eyeglasses frames. I had the idea to measure the thickness of the frame's contours (may be a better way?). I have so far outlined the frame of the glasses, but there are gaps where the lines don't meet. I thought about using HoughLinesP, but I'm not sure if this is what I need. So far I have conducted the following steps:
我想要做的是测量眼镜框的厚度。 我有想法测量框架轮廓的厚度（可能是更好的方法？）。 到目前为止，我已经概述了眼镜的框架，但是线条不符合的地方存在差距。 我想过使用HoughLinesP，但我不确定这是否是我需要的。 到目前为止，我已经执行了以下步骤： 将图像转换为灰度 围绕眼睛/眼镜区域创建ROI 模糊图像 扩大图像（这样做是为了去除任何薄框眼镜） 进行Canny边缘检测 找到轮廓 这些是结果： 这是我迄
Each set contains elements in a specified order. I want to specify a bound on the size of a set and automatically delete the last element if a new one strictly smaller (in terms of the order) is inserted and the specified size is already reached. Of course, I could do something like the following: class bounded_set { private: using set = std::set<Key, Compare, Allocator>; using
每个集合都包含指定顺序的元素。 我想指定一个集合的大小的边界，并自动删除最后一个元素，如果插入一个严格小于（按照顺序）的新的元素并且已经达到了指定的大小。 当然，我可以做如下的事情： class bounded_set { private: using set = std::set<Key, Compare, Allocator>; using iterator = typename set::iterator; public: bounded_set(std::size_t size) : m_size(size) { } std:
