compilation

问题 I am trying to use SDL. I have a folder in /Library/Frameworks called SDL2.framework . I want to include the file SDL.h in my project. How do I do this? My code looks like: // Example program: // Using SDL2 to create an application window #include <SDL.h> #include <stdio.h> int main(int argc, char* argv[]) { SDL_Window *window; // Declare a pointer SDL_Init(SDL_INIT_VIDEO); // Initialize SDL2 // Create an application window with the following settings: window = SDL_CreateWindow( "An SDL2

问题 I tried to search for that bug online but all the posts are for C++.

问题 I've attempted to compile, but every time I do, one method throws a strange "expected a type" error. I have a method in the header: -(ANObject *)generateSomethingForSomethingElse:(NSString *)somethingElse; The error points at the return type for this method. I've imported ANObject into the header using #import "ANObject.h" and ANObject is compiling fine.. Why is this happening? 回答1: This is to do with the order that the source files are compiled in. You are already probably aware that you can

问题 During the various stages of compilation in C or C++, I know that an object file gets generated (i.e., any_name.o file). What does this .o file contain? I can't open it since it's a binary file. Could anybody please help me? Are the contents of the object file mainly dependent on the compiler which we use on Unix? 回答1: Object files can contain a bunch of stuff: Basically it's some or all of the list below: Symbol Names Compiled code Constant data, eg. strings Imports - which symbols the

问题 If I get PermGen OutOfMemoryError from the app server when building my project in IntelliJ with Maven, is it the heap that Maven uses that I should increase?

问题 I have searched this, but I could'n find or understand what I found. Now I'm not a Java programmer, but I have the need to compile a single Java file into an existing (compiled) Java program. The source of this Java code is not available to me, therefore I cannot compile the entire project. I'm not interested in decompiling the original project. How to quickly do this using only the JDK and javac? (Through the command line is what I prefer.) I understand that to do so error checking outside

问题 This question already has answers here : How to use Clang compiler with MSBuild? (2 answers) Closed 2 years ago . I would like to override the default Visual Studio C++ compiler with a simple shell script. What I want is to capture the arguments, such as file name, and create some statistics. However I want to override the compilation process completely - that is, I want to call the original compilation from my shell script. I googled but all I found was how to have pre-build and post-build

问题 I have configured and compiled the FFmpeg library using this link: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu Now, I am trying to build example C codes provided by FFmpeg from here: https://github.com/FFmpeg/FFmpeg/tree/master/doc/examples However, when I run make install-examples or make install (suggested by /example/README), I receive this kind of message: make: *** No rule to make target '/doc/examples/README', needed by 'install-examples'. Stop. I thought this may be due to the

问题 I'm testing Java on a Windows Surface Pro. The Surface Pro has Java 7 Update 55, but does not have the JDK installed. I compiled a program on my MacBook from the command line using javac . The MacBook Has Java 8 Update 5 and it includes the JDK (obviously because I compiled on the MBP). When I move the program from the MackBook to the Surface Pro, I get the following error. Here, "moving the program" means copying the two *.class files to the new machine and trying to execute the byte codes.
