Need to test game development config

j_mitchell · April 27, 2011, 2:21am

Hi folks,

I’ve spent the last few hours trying to get a program to run. I’m using Kdevelop and SDL, but nothing even works. One program refused to run because of a permission issue (chmod doesn’t fix it). Another program DID work after a chmod 777, but then it had an error. See below:

jeff@linux:~/projects/Sppong> ./main.c
: No such file or directory
: command not found
./main.c: line 3: Sppong:: command not found
./main.c: line 4: syntax error near unexpected token `C'
'/main.c: line 4: `Copyright (C) 2010 Issam Abdallah
jeff@linux:~/projects/Sppong>

I’m getting sick of running programs, only to find that for one reason or another, the program doesn’t run. Can someone please send me a program which uses C or C++, along with libsdl? I’m sure that I have all the right packages installed, but I need to verify that, by running a program which is known to work.

I really need some advice on this. I’ve used Google repeatedly, but most of what I found was useless; most articles were vague guides on how to start programming in Linux. None of the articles got me anywhere.

So, in summary: I’m using OpenSUSE, Kdevelop, C++ and libsdl. Surely there is a simple program to test whether or not my configuration works? Yes I could write one myself, but I don’t want to learn C++ and all of libsdl, only to discover that my configuration is broken. I want to test my configuration first, then start a project after I know that my configuration is good. There is no point in working with potentially broken tools.

Please help.

This looks as if you want to run the source code of the c program. This will
of course fail, it is not a valid executable file (even if you make it
executable by chmod).
You need to run the resulting program from your compilation.
Can you show us the command you used to compile the program? So we can see
the name of the resulting binary.

Hi,

What is main.c? I’m assuming it’s the source code file, in which case
you need to compile the program before you try to run it.

I suggest you learn to program before you go any further, the best way
to do this is to buy a good book and work through the exercises.

Whoops, I just made an ass of myself again. Hahaha. Yes, that was a source file I just tried executing, oh dear. Sorry but I’ve been mashing the keyboard so fast and I’m running commands without thinking it through.

@Barry Nichols: I do actually know how to do programming. I’ve gone through half a book on C just recently (I own the book), and I’ve been on and off coding for years. I don’t have much trouble learning programming per se, it’s just the setup that troubles me. Also, I don’t have a degree in this subject.

Anyway, I’ve got another program from the sdl website. I even made the executable this time Here’s my terminal output:

Still doesn’t like me. I bet my left-one that it’s really obvious. Funny thing is, I checked the other thread and made my root partition exec, for executable. Yet I can’t execute a program.

Sorry, I just assumed because you were trying to run a source code file
that this was your first attempt at programming.

Just a guess, have you tried running the file called aliens?

…/aliens

Ahhhhh, it lives! In C, I thought that the “.o file” was the executable (at least by convention). I don’t know why** ./aliens** was the executable file, but thanks anyway. “Aliens” uses SDL, so many of the libs are clearly working.

Today I’ll be borrowing a C++ book off a friend, and then I’m going to take a stab at game development. This could be very positive.

Usually the .o file is the compiled object file of one source code file,
but this still has to be linked with other .o files and library files to
produce the executable program.

Glad you got it working, have fun.
