    Image displaying

    I need to learn a way, using a bitmap, to display an array of tiles (for a map) as colored squares. What is the easiest way this can be done and how can it be done?

    Yes you are going to need to install the headers and lib files for a library. This depends on your compiler.

    Check to see if your version of Dev-C++ has an update feature. It might be under help or tools. I know with the current version it not only lists updates put development packs as well. One of them should be Allegro.

    Alright, I downloaded and installed the Allegro Dev-pack. Should that be it before I can use it?

    I'm getting some error messages when I try to compile the program in the first tutorial: It's not telling me that the file <allegro.h> is undefined but it is telling me that there are undefined references to all of the functions in the tutorial. They are all classified as linker errors.

    A random guess is that you aren't including all of the libs in project settings, the specific errors would help

    Actually, scratch that. I did what prog-bman said about the projects and now there is only one error: 'no new line at end of file'. What is that supposed to mean?

    Hello,

    This seems to be a continous error. View this previous thread: No newline at end of file


    - Stack Overflow
    Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.

    Kind of a silly error and easily fixed. Make sure each of your code files (.c/.cpp and .h) has a blank line at the bottom.
