CMake and Visual Studio resource files

I am converting a C++ project created using Visual Studio 2005 to CMake and have stumbled upon a bit of a problem with resource files that are included in the project. The project includes a .rc file, a bunch of .ico files and a .rc2 file. The regular .rc file works fine in the generated project and uses the resource compiler. The .ico and .rc2 files however are causing problems when they ar

CMake和Visual Studio资源文件

我正在将使用Visual Studio 2005创建的C ++项目转换为CMake,并且偶然发现了包含在项目中的资源文件的一些问题。 该项目包括一个.rc文件,一堆.ico文件和一个.rc2文件。 常规.rc文件在生成的项目中正常工作,并使用资源编译器。 然而, .ico和.rc2文件在被包含时会导致问题,因为在生成的项目中Visual Studio会尝试使用C / C ++编译器对它们进行编译。 我假设这些文件包含在.rc文件中,所以它可能不会将它们包含在CMakeLi

How to call a parent class function from derived class function?

How do I call the parent function from a derived class using C++? For example, I have a class called parent , and a class called child which is derived from parent. Within each class there is a print function. In the definition of the child's print function I would like to make a call to the parents print function. How would I go about doing this? I'll take the risk of stating the o

如何从派生类函数调用父类函数?

我如何使用C ++从派生类调用父函数? 例如,我有一个名为parent的类和一个从父类派生的称为child的类。 每班有一个print功能。 在定义孩子的打印功能时,我想打电话给家长打印功能。 我会如何去做这件事? 我将冒风险说明明显的情况:如果在基类中定义了该函数,它就会在派生类中自动提供(除非它是private ),则调用该函数。 如果在派生类中有一个具有相同签名的函数,则可以通过添加基类名称和两个冒号base_class::fo

Memory leak detection for mixed mode projects: managed, unmanaged and native

I have a Visual Studio 2010 solution that contains C# (managed), C++/CLI (unmanaged) and pure C++ (native) projects. I would like to perform memory leak detection across all 3 projects or at least around the native code: The C# project references the unmanaged dll (I have access commonly available .NET Memory Profiling tools, so it's not really a problem to run memory profiling on it). T

混合模式项目的内存泄漏检测:托管,非托管和本机

我有一个包含C#(托管),C ++ / CLI(非托管)和纯C ++(本地)项目的Visual Studio 2010解决方案。 我想在所有3个项目中执行内存泄漏检测,或者至少在本机代码周围执行内存泄漏检测: C#项目引用了非托管dll(我可以访问常用的.NET Memory Profiling工具,因此运行内存分析并不是一个真正的问题)。 C ++ / CLI是本地C ++库的一个非常薄的包装器,所以我不需要描述它(不担心它)。 C ++本机代码是最难以描述的代码。

Template argument deduction fails on MSVC: bug?

The following fails to compile on VC++8.0 complier with an error (I haven't tried it on the latest visual studio complier yet.) error C2440: 'return' : cannot convert from 'const char *' to 'const char (&)[6]' template <typename T> inline T const& compare (T const& a, T const& b) { return a < b ? b : a; } int main() { ::compare("str

模板参数演绎在MSVC上失败:bug?

以下错误在VC ++ 8.0编译器中编译时出错(我还没有在最新的Visual Studio编译器上尝试过)。 错误C2440:'return':无法从'const char *'转换为'const char(&)[6]' template <typename T> inline T const& compare (T const& a, T const& b) { return a < b ? b : a; } int main() { ::compare("string1", "string2"); } 在函数模板里面,看起来字符串是const cha

C++ Negamax alpha

I've been using negamax to play connect four. The thing I noticed is, that if I add alpha-beta it gives sometimes "wrong" results, as in making a losing move I don't believe it should make with the depth I am searching at. If I remove the alpha-beta it plays how it is supposed to. Can the alpha-beta cut off some actually viable branches(especially when the depth is limited)?

C ++ Negamax alpha

我一直在使用negamax来连接四个。 我注意到的事情是,如果我添加alpha-beta,它有时会给出“错误”的结果,就像在做出失败的举动一样,我不相信它应该与我正在寻找的深度一致。 如果我删除了alpha-beta,它会播放它应该如何。 alpha-beta能切断一些实际可行的分支(特别是当深度有限时)吗? 以下是代码以防万一: int negamax(const GameState& state, int depth, int alpha, int beta, int color) { //depth end rea

Issue with MiniMax to Alpha

OK, my issue should sound pretty familiar to anyone who has played with board game programming, so here it is : I've implemented a variation of the MiniMax algorithm (returning moves instead of min/max values). I've also tried setting it up as an alpha-beta, although it ended up a complete failure. So, here's my MiniMax code : Move* Board::miniMax(int depth) { return this-&

问题与MiniMax到Alpha

好的,对于任何玩过桌面游戏编程的人来说,我的问题应该听起来很熟悉,所以这里是: 我实现了MiniMax算法的一个变体(返回移动而不是最小/最大值)。 我也尝试将它设置为alpha-beta,尽管它最终导致完全失败。 所以,这是我的MiniMax代码: Move* Board::miniMax(int depth) { return this->maxMove(1, depth); } Move* Board::maxMove(int ply, int depth) { vector<Move*> moves = this->possibleM

Are there any perfomance test results for usage of likely/unlikely hints?

gcc features likely/unlikely hints that help the compiler to generate machine code with better branch prediction. Is there any data on how proper usage or failure to use those hints affects performance of real code on some real systems? The question differs, but Peter Cordes's answer on this question gives a clear hint ;) . Modern CPU's ignore static hints and use dynamic branch pred

有没有使用可能/不可能提示的性能测试结果?

海湾合作委员会功能可能/不太可能的提示,帮助编译器生成更好的分支预测机器代码。 有没有关于如何正确使用或不使用这些提示影响真实代码在某些实际系统上的性能的数据? 这个问题不同,但彼得·科尔德斯对这个问题的回答给出了一个清晰的提示;)。 现代CPU忽略静态提示并使用动态分支预测。 我不知道有关这些特定提示的详细分析。 无论如何,这将是非常特定于CPU的。 一般来说,如果您确定可能性(例如,> 90%),

platform way to write Unicode to a file

I use Boost 1.60.0 on Windows, but I'm writing a cross-platform program. I'm trying to save filenames into a file and read them out later. The file may be text or binary and its encoding does not matter. I get the filenames by iterating through a directory using boost::filesystem::directory_iterator. The filenames may contain Unicode characters and I can't find a cross-platform w

平台的方式来编写Unicode文件

我在Windows上使用Boost 1.60.0,但我正在编写一个跨平台的程序。 我正在尝试将文件名保存到一个文件中,然后再读出来。 该文件可能是文本或二进制文件,其编码无关紧要。 我使用boost :: filesystem :: directory_iterator通过迭代目录来获取文件名。 文件名可能包含Unicode字符,我找不到跨平台的方式来编写或读取它们。 在Linux上,我可以通过使用boost :: filesystem :: path类的<<和>>运算符来实现withs

Handling file paths cross platform

Do any C++ GNU standalone classes exist which handle paths cross platform? My applications build on Windows and LInux. Our configuration files refer to another file in a seperate directory. I'd like to be able to read the path for the other configuration file into a class which would work on both Linux or Windows. Which class would offer the smallest footprint to translate paths to use o

处理文件路径跨平台

是否存在处理跨平台路径的任何C ++ GNU独立类? 我的应用程序建立在Windows和LInux上。 我们的配置文件引用另一个文件在一个单独的目录中。 我希望能够将其他配置文件的路径读入可在Linux或Windows上运行的类。 哪个类可以提供最小的空间来转换在任一系统上使用的路径? 谢谢 除非你使用绝对路径,否则根本不需要翻译--Windows会自动将正斜杠转换为反斜杠,所以如果你使用相对路径和正斜杠路径分隔符,你就会变成黄金。

How do you declare an interface in C++?

How do I setup a class that represents an interface? Is this just an abstract base class? To expand on the answer by bradtgmurray, you may want to make one exception to the pure virtual method list of your interface by adding a virtual destructor. This allows you to pass pointer ownership to another party without exposing the concrete derived class. The destructor doesn't have to do anyt

你如何在C ++中声明接口?

我如何设置一个表示接口的类? 这只是一个抽象的基类吗? 要扩展bradtgmurray的答案,您可能希望通过添加虚拟析构函数来为接口的纯虚拟方法列表创建一个例外。 这允许您将指针所有权传递给另一方,而不公开具体派生类。 析构函数不必做任何事情,因为接口没有任何具体成员。 将函数定义为虚拟函数和内联函数似乎是矛盾的,但相信我 - 事实并非如此。 class IDemo { public: virtual ~IDemo() {} virtu
