Hey,

I'm using the png.c code that OneSadCookie recommends to anyone who posts about textures.

When I try to run my app, I get the error message that it can't open the "texture.png" file.

Maybe this is an Xcode problem (or more precisely a lack of knowledge on my part problem!) but I have the file name specified as "texture.png" in the load_png_image() function call.

texture.png is located in the root of my project folder and then I put a copy in the build folder just in case. Is there a correct place to put resource files like that?

I'm pretty po'd trying to work out what the problem is at this stage, I had expected to have a nice textured quad on my screen but no joy as yet

It's been said many times before, but:
try putting the image in the same folder as your executable.
Alternatively, specify the absolute path to the image. If you're not sure what that is, open the terminal and drag the file into it. The path will appear, and you can copy and paste it into your application. Obviously this is not remotely portable, but will allow you to see your code load the image.

Putting it in the same folder as your executable won't help. When you open an application, the directory that's set is root by default. Search the forums and you'll find a way to move the current directory to your package directory. It's only been discussed thousands of times.

Okay so I figured out the directory thing but now when I run a build I'm getting a LOAD of undefined symbols.


Does this mean that I haven't setup the libpng libraries correctly? I ran the install application and it all seemed to work fine. I have included png.h in my project too.

Thanks for any help!

You need to add the PNG library to your project.

Sorry for such noob questions but a) what is the PNG library and b) how do I add a library to my my project?

the one you think you installed, that came with png.h, and by dragging it in.
