compilation

问题 I currently have the following routines in my Global.asax.cs file: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Arrangement", action = "Index", id = "" } ); } protected void Application_Start() { RegisterRoutes(RouteTable.Routes); // Debugs the routes with Phil Haacks routing debugger (link below) RouteDebug.RouteDebugger.RewriteRoutesForTesting

问题 The Java language specification specifies that In the Java programming language arrays are objects (§4.3.1), are dynamically created, and may be assigned to variables of type Object (§4.3.2). All methods of class Object may be invoked on an array. So, considering arrays are objects — why did the Java designers make the decision not to allow inherit and override from it, for example, toString() or equals() ? The current syntax wouldn't allow creating anonymous classes with an array as the base

问题 Here's my updated code: package car1; public class Main { public static void main(String[] args) { class HondaCivic implements car1 { int speed = 0; int rpm = 0; int gear = 1; public void speedUp(int Increment) { speed = speed + Increment;} public void applyBrakes(int Decrement) { speed = speed - Decrement;} public void changeRpm(int NewValue) { rpm = NewValue;} public void changeGear(int NewValue) { gear = NewValue;} public void printStates() { System.out.println("speed:"+speed+" rpm:"+rpm+"

问题 I have an .so file called tissue-classifier.cpython-37m-x86_64-linux-gnu.so from an external library that I want to import so that I can extend it in one of my local classes. Since I am extending a class, I need to import it as an extension type using cimport and I am wondering if this is even possible. If I use a normal import statement then I will be left with a Python compiled version which cannot be used to extend a cdef class in my current file. When I try to cimport the tissue

问题 I downloaded CHDataStructures source code (r709), and tried to compile the iOS static library under xCode 4. It complained when compiling: Can anyone give me some ideas how to compile it? 回答1: As the author of the framework, I was intrigued when Dave DeLong passed this link my way. Turns out this isn't due to Xcode 4, it's due to changes in the iOS 4.3 SDK (and incidentally, the 10.7 SDK too). I was using the OBJC_EXPORT macro with __attribute__((visibility("hidden"))) (for which I defined a

问题 /* test.c */ void func1() { } int main() { func1(); } Hello, I am making kernel code using C. But I tested above code to know how to build C kernel code. Below command is what I gave to prompt. I am using MinGW on Windows 8.1. gcc -c -m32 test.c ld -o test -Ttext 0x00 -e _main test.o But this error was occurred from ld. test.o:test.c:(.text+0x7): undefined reference to `__main' So, I tried different way. add -nostdlib and --freestanding option to gcc. But the result was same. Is __main

问题 I'm using reflection to load MyClass.class (an external file) at runtime. MyClass.class uses the library Bar , which would mean that I need to place import foo.Bar; at the top of the file. However, the Bar library is already loaded in the main class loading MyClass . Is there a way for me to tell javac to ignore that Bar doesn't exist and just compile without it? 回答1: No this is not possible. When compiling a class, the compiler has no "memory" of which classes were already "loaded" (don't

问题 I'm getting the following error when trying to compile OpenSSL 1.0, 64 bit: ias -o tmp32\ia64cpuid.obj tmp32\ia64cpuid.asm 'ias' is not recognized as an internal or external command, operable program or batch file. NMAKE : fatal error U1077: 'ias' : return code '0x1' Stop. Does someone know what can I do? (I do it on Windows 2008 x64 OS) Thanks. 回答1: You've probably chosen VC-WIN64I (as an argument for the perl Configure command), which is a wrong platform in your case. You should have passed

问题 I want to compile a C program in gcc which has my 2 header files. I am using the command: gcc UDP_Receive.c -o UDP_Receive -lm to compile it but I get an error stating "UDP_Data.h: No such file or directory" How can I tell the compiler to include these header files? Header Files: #include "UDP_Data.h" #include "Crypt.h" Thanks, Ritesh 回答1: Use -Idirectory to add include paths, or make your #include statement use relative paths. EDIT: Also be aware that #include filenames are case sensitive on
