  • mac, netbeans 6.8, c++, sdl, opengl: compilation problems

    - by ufk
    Hiya. I'm trying to properly compile a c++ opengl+sdl application using netbeans 6.8 under Snow Leopard 64-bit. I have libSDL 1.2.14 installed using macports. The script that I try to compile is the following: #ifdef WIN32 #define WIN32_LEAN_AND_MEAN #include <windows.h> #endif #if defined(__APPLE__) && defined(__MACH__) #include <OpenGL/gl.h> // Header File For The OpenGL32 Library #include <OpenGL/glu.h> // Header File For The GLu32 Library #else #include <GL/gl.h> // Header File For The OpenGL32 Library #include <GL/glu.h> // Header File For The GLu32 Library #endif #include "sdl/SDL.h" #include <stdio.h> #include <unistd.h> #include "SDL/SDL_main.h" SDL_Surface *screen=NULL;

Linker: I added the following libraries: /usr/X11/lib/libGL.dylib /usr/X11/lib/libGLU.dylib /opt/local/lib/libSDL.dylib /opt/local/lib/libSDLmain.a Now... before I included SDL_main.h and libSDLMain.a to the project I got an error unknown reference to _main then I read here: http://www.libsdl.org/faq.php?action=listentries&category=7#55 that I need to include SDL_Main.h and to link libSDLMain.so to my project. after doing so, the project still won't compile. this is the Netbeans output: /usr/bin/make -f nbproject/Makefile-Debug.mk SUBPROJECTS= .clean-conf rm -f -r build/Debug rm -f

    - by ufk
    Hiya I'm trying to write an application for red5 that uses some servlet classes in order to package a requestion for facebook. the client side is a Adobe flash builder application. is it possible to send session information from the flex application in order for the red5 client side to create proper HttpServletRequest and HttpServletResponse objects? in tomcat the code would be: public void doGet (HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { HttpServletRequest request = (HttpServletRequest)req; HttpServletResponse response = (HttpServletResponse)res; ... }

  • flex: is there a way to dispach a custom event from one loaded flex application to the other ?

    - by ufk
    Hello. I have an HTML page that loads two different SWF files. is there a way to dispatch a custom event from one flex application to another ? to create a custom event I extend the Event class and I add another variable to the constructor called params which is an Object. I use EventDispatcher to dispatch the events. I have no idea how to do that between one flex application to the other. is it even possible ? If it's not, is there any other way that these two flex applications can communicate without opening a LocalConnection ? Using flex 4.5 thanks!
