compiler-errors

问题 I have an error message that I don't understand. I downloaded on the www.swift.org the swift toolchain 4.0.3 because I had an error message "Module compiled with Swift 4.0.3 cannot be imported by the Swift 4.2 compiler:" Now, it makes me a different message: CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compiler (in target: CameraDemo) cd /Users/OlostA/Desktop/Git/r-d/CamBox export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer export SDKROOT=/Applications/Xcode.app

问题 This is a follow up to this question found here! Now, that I'm able to instantiate the object. I'm now getting a Visual Studio C2440 Compiler Error... In my original code before it was templated I had a set of member functions that worked on the std::function<double(double)> member object that looked like this: struct SomeStruct { double a_; double b_; SomeStruct(double a, double b) : a_{a}, b_{b} {} }; class SomeClass { private: SomeStruct fields_; size_t n_; std::function<double(double)>

问题 I recently started learning C++, and I'm currently trying to test out the header file functionality. I wrote three simple files: headertest.h: #pragma once class Cube { public: double getVolume(); double getSurfaceArea(); void setLength(double length); private: double length_; }; headertest.cpp: #include "headertest.h" double Cube::getVolume() { return length_ * length_ * length_; } double Cube::getSurfaceArea() { return 6 * length_ * length_; } void Cube::setLength(double length) { length_ =

问题 I am building out my first Redis server side script ( for debugging ) and my lack of Lua experience has me quite stuck. Essentially have a dataset of K/V pairs (containing ~1000 values) from which I want to list all the KEYS that match a pattern. For example in redis-cli: > KEYS "carlos:*" 1) "carlos:1" 2) "carlos:2" 3) "carlos:3" 4) "carlos:4" Based on the above output I want to return the sum of those keys by executing a Lua script. Currently I have the following on my sum.lua local sum = 0
