Samples/Demo6 broken by including Irrlicht

[Kelson]

This is kind of a confusing problem. I download and statically build Irrlicht, then download and statically build CEGUI.

If I use this line, everything works as expected (Samples/Demo6/Demo6 executes properly w/ OpenGL renderer)

Code: Select all

./configure --enable-debug --disable-expat --disable-xerces-c --with-irrlicht-incdir=/usr/local/share/irrlicht/include --with-irrlicht-libdir=/usr/local/share/irrlicht/lib/Linux --enable-static --disable-shared --disable-irrlicht-renderer

But if I use this line... executing Samples/Demo6/Demo6 w/ OpenGL fails

Code: Select all

./configure --enable-debug --disable-expat --disable-xerces-c --with-irrlicht-incdir=/usr/local/share/irrlicht/include --with-irrlicht-libdir=/usr/local/share/irrlicht/lib/Linux --enable-static --disable-shared --enable-irrlicht-renderer

Here's the output

Code: Select all

CEGUI::RendererException in file CEGUIOpenGLTexture.cpp(139) : OpenGLTexture::loadFromFile - DevILImageCodec - Official DevIL based image codec failed to load image 'logo.png'.
An exception was thrown within the sample framework:
OpenGLTexture::loadFromFile - DevILImageCodec - Official DevIL based image codec failed to load image 'logo.png'.

Clearly there is a problem with PNG loading, although I'm not sure why that should be the case (both build statements appear functionally identical)

If I replace all the PNGs with GIFs, the OpenGL renderer loads properly (albeit with the random GIF I grabbed).


Tangentially, the Irrlicht renderer for Demo6 (for example) just renders a blank/black screen initially. After replacing the PNGs with GIFs, it barfs on the invalid images. The lack of any visible interface seems consistent with what I was experiencing in my application, sadly. Not quite sure what is up with CEGUI barfing on PNGs following Irrlicht inclusion though.


edit: just to head off future problems, I rolled back to Irrlicht 1.7.2, but this seems to have fixed the problem. I'm just going to leave this here as a warning against pairing up unstable versions in early dev
