compilation

问题 I'm trying to execute a Python program on Linux which I first created on Windows, but the following error is shown: metadata = eval(metafile.read()) File "< string >", line 1 @ @ @ @ @ @ Any idea? 回答1: dos2unix yourfile.py python yourfile.py If you don't have dos2unix , here is some python code you can use instead. Just put this in dos2unix.py, and run python dos2unix.py yourfile.py above: import sys filename = sys.argv[1] text = open(filename, 'rb').read().replace('\r\n', '\n') open(filename

问题 I know C# code can be compiled at runtime using C#. However I'm very very shaky at it since I just read about it a few minutes ago. I learn a lot better by examples. So tell me. If I want to compile something like: // MapScript.CS String[] LevelMap = { "WWWWWWWWWWWWWWWWWWW", "WGGGGGGGGGGGGGGGGGW", "WGGGGGGGGGGGGGGGGGW", "WWWWWWWWWWWWWWWWWWW" }; and use this array in my code, how would I go about it? In pseudocode I want to do something like this: Open("MapScript.CS"); String[] levelMap =

问题 I have code of the following structure (which is of course much more complex in reality, especially "Base" is a three-liner, but I've tried to capture the gist of it): template <class T> class A {}; template <class T> class B { public: B(){}; }; template <class T> class C : public B<A<T>> { public: using Base = B<A<T>>; using Base::B; }; static const C<int> c{}; The code compiles fine with g++ via g++ -c test.cpp -std=c++11 However, with clang++ I get an error message I don't really

问题 I tried to compile this and got mistakes such as: Error 4 error C2440: 'initializing' : cannot convert from 'void *' to 'char *' This code is taken from here. Why doesn't it work? DWORD dwRead=0; char *lpData = (VOID*)GlobalAlloc(GMEM_FIXED, MAX_READ), 回答1: You appear to be compiling with a C++ compiler, so you'll need an explicit cast: char *lpData = (char *)GlobalAlloc(GMEM_FIXED, MAX_READ); 来源： https://stackoverflow.com/questions/15105980/error4error-c2440-initializing-cannot-convert-from

问题 I have some simple hypothetical static class in C++: #ifndef __STAT_H_ #define __STAT_H_ class Stat { private: static vector<int> v; public: static void add_num(int num); static void clear_nums(); static void get_count(); }; #endif And the ccp file is so: #include "Stat.h" vector<int> v; void Stat::add_num(int num) { v.push_back(num); } void Stat::clear_nums() { v.clear(); } int Stat::get_num_count() { return v.size(); } Now when I include in main.cpp file "Stat.h" and try to use some static

问题 Where are they stored? And is there a way to determine when they get deleted? Is there a way to make it so that they are never deleted, so as to improve performance for example? Another issue - in a busy hosting environment how big could all the dll's get? Let's say if you have 1000 medium websites? 回答1: Where are they stored? It depends on if you compile them before deployment or after deployment. If you compile them before deployment you will deploy them directly to the /bin folder of your

问题 I'm trying to follow this jenkins tutorial: https://www.youtube.com/watch?v=FonVQNqLWiE&list=PL6tu16kXT9PqIe2b0BGul-cXbmwGt7Ihw&index=7 but I'm trying to do that within a dockerized jenkins. To do so, instead of creating a windows virtual machine, I just run the official jenkins docker image: $ docker pull jenkins/jenkins:lts $ docker run -P jenkins/jenkins:lts To follow it up to chapter #6, to make sure maven is available I enter into the container with this: $ docker exec -it -u root
