compilation

问题 I'm trying to sell myself to the idea of trying to build enhanced Jquery Mobile markup on the server (running Coldfusion8 ) and then try to use DustJS (Javascript templating engine) to precompile the markup into a js string, which I want to server as a static file. I think I have it down to trying to add the plugin in Coldfusion. Here is what I want to do: Start with a template like this in Coldfusion: <cfsavecontent variable="renderedResults"> <cfoutput> {##person}{root}: {name}, {age}{

问题 How is it possible that following code even compiles? As far as I can see the count function is called with two different types, yet compiler doesn't complain and happily compiles this code. public class Test { public static <T> int count(T[] x,T y){ int count = 0; for(int i=0; i < x.length; i++){ if(x[i] == y) count ++; } return count; } public static void main(String[] args) { Integer [] data = {1,2,3,1,4}; String value = "1"; int r =count(data,value); System.out.println( r + " - " + value)

问题 I understand the gist of how JIT compilation works (after reading such resources as this SO question). However, I am still wondering how does it actually execute the machine code at runtime? I don't have a deep background in operating systems or compiler optimizations, and haven't done anything with machine code directly, but am starting to explore it. I have started playing around in assembly, and see how something like NASM can take your assembly code and compile it to machine code (the

问题 I have the full name & path of an executable, e.g. C:\IW4\BIN\iw32.exe , and want to extract the compilation date and time of that executable. How can I do this? I couldn't find any suitable solution. My C++ program must compile under Windows using Borland C++ Builder, if that info is of any worth. EDIT: I found some sample code and it works, thanks for all your pointers and hints! The Code is : #include <stdio.h> #include <windows.h> int main (int argc, char** argv) { WIN32_FILE_ATTRIBUTE

问题 I have succesfully compiled the LLVM kalidoscope examples in C. Now I'm extending the code with: #include "llvm/Support/CommandLine.h" static cl::opt<std::string> InputFilename(cl::Positional, cl::desc("<input file>"), cl::Required); int mail(... now i compile using: clang++ -g toy.cpp llvm-config --cppflags --ldflags --libs all -O3 -o toy and after this change i receive the following error: Undefined symbols for architecture x86_64: "typeinfo for llvm::cl::GenericOptionValue", referenced

问题 I have installed Go from gomingw for windows 64 bit. However, I cannot find out anywhere how to actually compile a .go file. This is the program linked directly from the Go wiki for Windows Support, but all the tutorials talk about using 6g and gccgo etc. and none of those work on my windows machine. Actually, what I am trying to do is, I put my "hello.go" in src folder and after going to src folder I run the command "8g hello.go" in command prompt. But. it showing error "open a.go no such

问题 and if the answer is "it depends", could you provide a short explanation why ? 回答1: GAC is meant to contain assemblies that are shared across multiple applications . If that is the case, you should strong-name the assembly and register it with the GAC. If not, keep the assembly as a private assembly and reference it as a project/dll reference. PS: Didn't really get the reference from bin folder part of your question - which bin folder is this? 回答2: At the risk of drawing downvotes I'm going

问题 Below is the code that defines class type: package annotationtype; public class Example { public static void main(String[] args){ } } that gets functionally compiled by javac to: public class annotationtype.Example{ public static Class<annotationtype.Example> class; { class = Class.forName("annotationtype.Example") } public annotationtype.Example(){} public static void main(java.lang.String[] args){} } My major focus is on the Class<annotationtype.Example> class static member variable in the

问题 I am not sure how appropriate is this question, but - I am curious about how the compiler sets memory aside for an object (allocation of memory) even before it is constructed (before even the constructor is called!) . How does it happen for primitive datatypes? This sounds a bit naive, but what exactly is it ? Is it entirely a run time process, or does it (the compiler) have any plans like to do this , to do that , during run-time, which it decides before hand during the compile- time . I

问题 As well as runtime checks for deciding on code paths for an iphone/ipad app, is there a conditional compilation flag anywhere that can be used to reduce code size? Apple seems to suggest it in their development notes, but I can't find anything anywhere. How do others do this? Thanks 回答1: You can use the following function and check for if isPad then do code for iPad else code for iPhone - (BOOL) isPad{ #ifdef UI_USER_INTERFACE_IDIOM return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad
