Hi,
i moved our engine from jogl / joal to lwjgl a few weeks ago. Yesterday a tester detected errors when using dds textures. First i thought it has to be a hardware problem (graphics hardware does not support the texture compression format), but as i figured out today, the problem exists on every hardware.
I cannot find the mistake i am making and also double checked if something went wrong when the engine was ported.
The current system i am working with is a nvidia 7600 GS with the following information provided by the driver:
OpenGL Version : 2.1.2
OpenGL Vendor : NVIDIA Corporation
OpenGL Renderer: GeForce 7600 GS/PCI/SSE2
Available Texture Compression:
COMPRESSED_RGB_S3TC_DXT1_EXT(33776)
COMPRESSED_RGBA_S3TC_DXT3_EXT(33778)
COMPRESSED_RGBA_S3TC_DXT5_EXT(33779)

The texture format is DDS_PixelFormat.FOURCC_DXT1 so i am using EXTTextureCompressionS3TC.GL_COMPRESSED_RGB_S3TC_DXT1_EXT as internal format for opengl. The "bb" byte buffer of the image data is in native order and direct. To upload the image data i use
GL11.glBindTexture(texType, id);
GL11.glTexParameteri(texType, GL11.GL_TEXTURE_MIN_FILTER, minFilter.getID());
GL11.glTexParameteri(texType, GL11.GL_TEXTURE_MAG_FILTER, magFilter.getID());
GL11.glTexParameteri(texType, GL11.GL_TEXTURE_WRAP_S, wrapMode_s.getID());
GL11.glTexParameteri(texType, GL11.GL_TEXTURE_WRAP_T, wrapMode_t.getID());
ARBTextureCompression.glCompressedTexImage2DARB(GL11.GL_TEXTURE_2D, i, cData.getFormat(), nWidth, nHeight, 0, bb);
nWidth and nHeight are both 256 and the buffers capacity, limit, position is correct.
When calling this, i get an GL11.GL_INVALID_OPERATION Error.
I read the methods docu
http://www.opengl.org/sdk/docs/man/xhtml/glCompressedTexImage2D.xml but couldn't find out what the problem is. In fact, i worked the code did work before switching from jogl to lwjgl. By the way GL13.glCompressedTexImage2D results in the same error...
Any suggestions anyone? Would be great..
Faust.
