问题 I have created an executable using "include $(BUILD_EXECUTABLE)" command in Android.mk . My requirement is to execute the above generated executable over the abd shell. I tried: Below is my C-Code which is compiled using ndk-build command: #include <stdio.h> int main() { printf("\n\nHello World\n\n"); return 0; } Following is my Android.mk file contents: LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := HelloExecutable LOCAL_SRC_FILES := hello.c include $(BUILD_EXECUTABLE)

问题 I'm currently porting a Python2 script to Python3 and have problems with this line: print('\xfe') When I run it with Python2 python test.py > test.out , than the file consists of the hex-values FE 0A , like expected. But when I run it with Python3 python3 test.py > test.out , the file consists of the hex-values C3 BE 0A . What's going wrong here? How can I receive the desired output FE 0A with Python3. 回答1: The byte-sequence C3 BE is the UTF-8 encoded representation of the character U+00FE.

问题 As a step in switching from NLog to Serilog, I want to redirect the standard wiring underlying standard invocations of NLog's LogManager.GetLogger(name) to Bridge any code logging to NLog to forward immediately to the ambient Serilog Log.Logger - i.e. I want to just one piece of config that simply forwards the message, without buffering as Log4net.Appender.Serilog does for Log4net. Can anyone concoct or point me to a canonical snippet that does this correctly and efficiently please?

问题 I am porting a linux application to the iphone and I would like to know how much re-writing I have to do to make it a multi-threaded application rather than a multi-process application. Also, if I simply replace the forked code with a call to the functions on another thread I get exec_bad_address at seemingly random places in my flow of execution... Does anyone know why this may be the case? Thanks! 回答1: It is exactly the same effort you would undergo in transitioning your application to a

问题 This question already has answers here : NSArray Equivalent of Map (10 answers) Closed 4 years ago . What's the Objective-C equivalent of JS's map() function? Would I just use NSFastEnumeration and apply the function myself? 回答1: You can use NSArray 's enumerateObjectsUsingBlock: if you're on OS X 10.6 or iOS 4.: NSMutableArray *mapped = [NSMutableArray arrayWithCapacity:[array count]]; [array enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { id mapObj = DoSomethingToObject

问题 This question already has answers here : SQL Server equivalent to Oracle's CREATE OR REPLACE VIEW (9 answers) Closed 3 years ago . CREATE OR REPLACE VIEW doesn't seem to work in SQL Server. So how do I port CREATE OR REPLACE VIEW to work on SQL Server? This is what I'm trying to do: CREATE OR REPLACE VIEW data_VVVV AS SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A ; Any ideas? 回答1: Edit: Although this question has been marked as a duplicate, it has still been getting

问题 I have a C++ class that compiles fine on linux with gcc and on widows in visual studio. boid.h: #ifndef BOID_CLASS_HEADER_DEFINES_H #define BOID_CLASS_HEADER_DEFINES_H #include "defines.h" class Boid { public: // Initialize the boid with random position, heading direction and color Boid(float SceneRadius,float NormalVel); ..... protected: ... }; #endif and in boid.cpp: #include "Boid.h" // Initialize the boid with random position, heading direction and color Boid::Boid(float SceneRadius,float

问题 With some changes in the staffing at the office, the levels of C# expertise has dropped off precipitously and there are now more Java developers. It has gotten to the point where the higher-ups are considering moving an existing .NET project written in C# into the Java world. Aside from the obvious problem of starting completely from scratch what are the possible ways that this company can accomplish a successful move of development on a project from .NET C# into Java? 回答1: Here are things to

问题 As far as I can tell, Java has no such equivalent of C#'s Reflection.Emit stuff. Are there any additional libraries for Java that provide similar functionality? What are the differences (to reflection emit )? 回答1: Besides Darin's excellent answer (+1), ASM is worth checking out too. 回答2: The Byte Code Engineering Library (BCEL) 来源： https://stackoverflow.com/questions/2259323/java-equivalent-of-reflection-emit

问题 I am porting some c++ code to c. What is a viable equivalent of std::map in c? I know there is no equivalent in c. This is what I am thinking of using: In c++: std::map< uint, sTexture > m_Textures; In c: typedef struct { uint* intKey; sTexture* textureValue; } sTMTextureMap; Is that viable or am I simplifying map too much? Just in case you did not get the purpose its a Texture Map. 回答1: Many C implementations support tsearch(3) or hsearch(3). tsearch(3) is a binary tree and you can provide a
