SOIL: new lightweight image loading lib

lonesock · 2010-05-28T18:12:52

Hi, All. This is an announcement, but I think it fits better in this forum. If I'm wrong, feel free to move it [8^) I've been looking for a tiny image loading library for some hobby OpenGL game projects I'm working on, but never really found exactly what I wanted. Then I found Sean Barrett's awesome C code for loading BMP/PNG/JPG files (here). I took that, added TGA loading support (except for indexed TGA images), wrapped some common functions like upsizing to power-of-two sizes, MIPmap generation, pre-multiplying alpha, etc. all into a single function call for easy loading of textures into OpenGL. Presenting the Simple OpenGL Image Library (yes, I'm sorry SOIL is such a lame acronym [8^) Features: Loads PNG, JPG, TGA, BMP, DDS (a subset of each type) Saves TGA, BMP, DDS Loads an image file directly into an OpenGL texture Can automatically rescale the image to the next largest power-of-two size Can automatically create MIPmaps Can multiply alpha on load (for more correct blending / compositing) Can flip the image vertically Can compress to DXT1 or DXT5 (if EXT_texture_compression_s3tc is available) Will downsize the image if necessary to fit GL_MAX_TEXTURE_SIZE No external dependencies Tiny Public Domain If anybody is willing to give some feedback, I'd really appreciate it (I'm keeping this a C project, and my C skills are extremely rusty). Feature requests are also welcome. [edited to add new features] [Edited by - lonesock on August 16, 2007 11:59:53 AM]

Hi, I am working on redhat.
Can someone exactly tell me how to link the library.
I put libSOIL.a in /usr/lib folder and SOIL.h file in /usr/include folder.

I included this line in my C++ program #include <SOIL.h>

On compiling it gives the following errors:

/tmp/cc1dkSnQ.o(.text+0x166): In function `glutDisplay()':
: undefined reference to `SOIL_load_OGL_texture'
/tmp/cc1dkSnQ.o(.text+0x17d): In function `glutDisplay()':
: undefined reference to `SOIL_last_result'
collect2: ld returned 1 exit status

Can someone please tell me what's wrong?

How are you invoking gcc? You'll probably need (iirc) a -LSOIL.
