Yeah I noticed that. I really have no idea why it helped, but Houdini runs now.

Hi there I followed Edward's tip but no success.

$ cd /opt/hfs10.0.465
$ source houdini_setup
$ echo $HOUDINI_BUILD_KERNEL

This gave me the following result.
2.6.20-16-generic

$ cd hsvg
$ ./hsvg $HH/help/nodes/images/fov.svg -o/tmp

This gave no error.

SPEC:
Kubuntu 9.10 32 bits
Houdini hfs10.0.465
nVidia

PROBLEM:
I can see icons but the UI is very very slow and unoperable. The houdini window often goes black and colour streaks in it. Resizing the window slows down the app greatly.. pretty much unusable.

Thank you.

Do you have the proprietary nvidia driver installed? Also, if you have desktop effects enabled it's worthwhile disabling them in your xorg.conf.

Try this

glxinfo | grep direct

Thanks Alan.

This is what I got from the command.
direct rendering: Yes
GL_EXT_direct_state_access, GL_EXT_draw_range_elements, GL_EXT_fog_coord,

I have nVidia driver(185.18.36) runing, and the system says im using proprietary drivers.

#deb cdrom karmic main restricted

From the top Ubuntu menu, choose System > Preferences > Appearance. Now switch to the Visual Effects tab and make sure that it is set to None.

Hi Edward, i'm trying to find the option in Kubuntu. How do I get to the visual effects tab?

The screenshot below is from ‘appearance window’.

ah i see.. if anyone uses kubuntu 9.10 like myself this may help.

System settings -> Desktop -> Enable desktop effects OFF

I didn't realize Kubuntu differed so much from regular Ubuntu. I figured the system menus were at least roughly the same but I guess not.

thanks a lot edward…it worked for me too!!

I have the same Issue, my sops dont find or recognize the icons…i just cant use ….the command for execute the hsvg returns


# ./hsvg $HH/help/nodes/images/fov.svg -o/tmp
/opt/houdini/hsvg/hsvg-real: symbol lookup error: /usr/lib/libgthread-2.0.so.0: undefined symbol: g_thread_gettime


i dont know how to fixed….i'm not using ubuntu but Arch Linux 32bits…
Somebody can help me? on Arch 64 dont have problem

Thanks a lot this has worked for me too on Kubuntu 11.04 and Houdini 11.775

Here's an idea to try if you're willing to modify your installation. It probably won't work though. And I can't test since I don't generally run Linux.

$ cd /opt/hfs10.0.465
$ source houdini_setup
$ echo $HOUDINI_BUILD_KERNEL
(make sure this mentions amd64 if you're on a 64-bit OS)
$ cd hsvg
$ ./hsvg $HH/help/nodes/images/fov.svg -o/tmp


Confirm that this brings up the libgio error. If there's no error, then something else is wrong. Assuming this brings up the libgio error, we can try to figure out which libs are causing the problem:
$ sudo mkdir oldlibs
$ sudo mv lib* oldlibs


This moves all the libraries that might conflict into the oldlibs directory so that they are no longer used. Ok, now we try using hsvg again:
$ ./hsvg $HH/help/nodes/images/fov.svg -o/tmp


If the hsvg command produces no errors or warnings, then we're done. We should remove the icon cache before restarting houdini:
$ cd ~
$ rm -r ~/houdini10.0/config/Icons
$ houdini -foreground


If running hsvg still doesn't work, then you need to systematically find the right combination of libraries from oldlibs that causes hsvg to run by copying them back out. Post your results if you figure this out.

There are probably other Ubuntu 9.10 problems but this is a start if you're really desperate to run Houdini on Ubuntu 9.10. (Note the official stance [sidefx.com] on Ubuntu 9.10 right now.)

Thanks Edward, that just worked perfectly for Houdini 11.1.118 under Ubuntu Linux 11.04.

@edward: for the libgio error, all the respect man!!!!!

just installed Mint13 Mate and stopped here ..

the error message i was getting was :
/opt/hfs11.1.285/hsvg/hsvg-real: symbol lookup error: /opt/hfs11.1.285/hsvg/hsvg-real: undefined symbol: _rsvg_size_callback

and i simply turned back on its orginal folder the librsvg-2.so.2 with :
sudo cp ./oldlibs/librsvg-2.so.2 ./



houdini 's ui is fully flourished with those cheerfull colors again !

hope this helps someone in near future ..



.cheers

Er, why bother when you can use H12 without the icon problems?

while H11 is still available for download , why not ?

Had the same problem with hsvg-real on Slackware64 14.0 running 11.1.388. Moving the libraries to a separate oldlibs folder didn't solve the problem. All icons were white. A brute force solution which seems to work is to copy the entire hsvg folder from an existing 12.1 installation. Remove the SVGIcons.cache files and start Houdini.

As for matsbt, I had the same troubles using Fedora 17. Icons didn't work using Houdini 10.x and Houdini 11.x. Only Houdini 12.x works.
I too used an existing icon cache from another OS install. Worked perfectly! As long as that hsvg command is not used for anything else?

Thanks Zarti!!

One of my old licenses for Houdini 11 was having icon issues and the typically icon restore procedures were not working. Your suggestion fixed my problem.

Best!
