Bug 273738 – media-gfx/yafaray-0.1.1 Ebuild Request

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Robert Krig 2009-06-11 15:39:04 UTC]

Yafaray is a opensource Global Illumination Rendering Engine.

Yafray up to version 0.9 was tightly integrated into Blender. However, that branch is no longer being developed. Yafaray is new and improved and is a standalone renderer. It has good integration with Blender thanks to its export scripts and is much faster than the old Yafray.
Considering that this is a Global Illumination Renderer, it would be cool to have a gentoo ebuild for it. Since every bit of optimization helps to keep the render times down.

Reproducible: Always

[Comment 1 SATtva 2009-06-14 18:41:11 UTC]

I'd like to add that since blender-2.49 (see bug #272861) integrated support for the old yafray has been dropped in favor for yafaray, so media-gfx/yafray would become mostly obsolete, and there's a need for the new version of the renderer in the portage.

[Comment 2 Robert Krig 2009-07-03 18:28:02 UTC]

mmaekke, you are the ebuild maintainer for Yafray.
Would you perhaps have interest in maintaining the new Yafaray. Its become very useable and surpasses the old yafray in almost every way.

yafaray-0.1.1.ebuild

I've created an yafaray-ebuild and added it to my overlay [1]. could you verify if it actually works? =)

Sweet! That just made my day.

The ebuild seems to be missing the ~amd64 keyword.  I've added it manually.
Compiles fine on my AMD64 Gentoo System.

Test rendering failed. Yafaray shows up in Blender, but for example the material render previews dont work, nor does rendering a scene.

Here's the output from the console when I try to render a scene:

------------------------------------------------------------------

creating new QApplication

finished, setting pixmap
~yafrayInterface_t()    delete scene...delete environment...done
-----------------------------------------------------------------------

The QT interface in Blender works. It just seems that Yafaray doesn't seem to know about its own shaders and rendering options.
Either that or the script is looking for some things in the wrong place.

It could also be just my system. I used to have Ubuntu on here. Since I've installed Gentoo again, I've kept my home directory.
Could it be that yafaray stores its settings in some directory or File I wasn't aware of and is still trying to find the relevant data in Directories which ubuntu had?

[Comment 5 Robert Krig 2009-08-01 15:42:13 UTC]

I did some further testing. I removed all blender related files and directories from my home directory. This time I use the "export to xml" function of yafaray. To see if it would render with the yafaray-xml commandline client.

No luck! It still chokes with the same error messages about not knowing how to create a integrator of a certain type.

Hmm... Judging by the error message, It seems like Yafaray is unable to call or find any of its own functions. All the Blender related stuff seems to work. The script adds objects and materials as it should. But chokes on anything which is strictly yafaray. e.g. Photonmapping, sunsky background, lighting methods, material shaders... etc.

I don't know if AMD64 could cause this error. I'm gonna test this out on my x86 laptop when I get the chance.

[Comment 6 Reuben Martin 2009-08-01 20:54:59 UTC]

Confirmed same type of problem.

x86, blender 2.49.2, python 2.6.2

Yafaray ebuild with re-hardcoded plugin-path

I had the exact same problem and (think I) solved it:

The problem is that the build process of yafaray is very naive and believes that the given PREFIX will actually be the position where the files will be installed; It uses this knowledge to hardcode (!) the path to the plugins in the plugin-loading mechanism thus making it impossible to find the plugins when the installed files get moved to the live system.

You can try this, if you want, by emerging yafaray as normal and additionally perform a 'ebuild <path/to/yafaray.ebuild> install' to generate the files at the hardcoded position. Yafaray should then also work as long as you keep the files...

Fortunately, you can again hardcode the plugin path to anything you like without breaking the build process.

The attached ebuild does just this. I tried some different things that looked smarter but they mostly broke the build process...
One thing to mention: the path is really hardcoded; if the libraries do not end up in '/usr/lib/yafaray' it will again not work...

Happy blending!

Have you managed to get it working? yafaray-0.1.1-r1.ebuild builds correctly (with gcc-4.3.2-r3), renderer gui and materials preview works, but trying to render a scene leads to segfaults:

It works for me on x86 and amd64:
blender-2.49a, gcc-4.3.2, python-2.5.2-r8, qt-4.4.2 (on the amd64, the x86 box should be similar)

I have really no idea whats wrong, but I would guess it's either a problem with the python-binding or with qt.

Thanks!! That did it!

It works perfectly now on my AMD64 System.

Thanks again to everyone involved.

I'm no programmer, but from that log output it looks to me as Yafaray is properly doing its thing UNTIL it tries to create a QT Window. All the other stuff seems to be working. e.g. Add shaders and materials and preparing the geometry.

I would suggest you try a revdep-rebuild and see if that comes up qith an QT related broken dependancies.

Compiles fine, and can tell blender to use it to render, but when i try to render, i get this error message:

It is an amd64 box, with gcc-4.3.2, blender-2.49a python-2.6.2-r1 and qt-4.5.1

I think that there is a problem with the interface from Python to Qt. It is only a guess, but maybe you need to update dev-lang/swig or Qt. You also have to make sure that blender is compiled against the same python version that the yafaray ui uses. Maybe the fasted try would be an update to swig (and then re-emerging yafaray).

My swig here is pretty old (1.3.31, emerged a year ago) but I am also still using python 2.5.2.
