Ellipsoid

Hi, the problem is that the woo.utils.ellipsoid function was not added until rev. 3348, so you seem to be running a newer example script (ell0.py and ell1.py) with an older version (rev. 3342).

If you can, build the package locally (we have a problem with launchpad buildbots running out of RAM for compilation, so not all versions have their packages; and we can do nothing about that); ideally, follow the procedure from https://launchpad.net/woo/:

     sudo apt-get build-dep woo # needed just once
     apt-get source --build woo # compile binary package from source pkg
     sudo dpkg -i python-woo. ... .deb # install the package; replace the ... by the actual version number

Hi, Vaclav, Thank you for your kind reply. Unfortunately, I cannot compile the binary package.

when I input $ apt-get source --build woo, it compiles several files and then following errors occur. would you please give me some suggestions.

Hi Jie Quin, it looks like you don't have enough RAM - do you have at least 4GB of it?

   x86_64-linux-gnu-gcc: internal compiler error: Killed (program cc1plus)

indicates that the process was killed, which happens when it exhausts RAM - the then kernel kills it to keep the rest of the OS functioning.

HTH, Vaclav

If you don't have enough RAM, you can use clang to build Woo, though not sure how that works on 12.04 - I will update the docs about that if you need it. I will also try to re-build the package over and over so that there is eventually one built for 12.04 on amd64. Sorry for inconveniences.

Hi, Vaclav, thank you for your continuos help. Yes, you are right, it is attributed to the limited size of RAM. Now, all the files are successfully buit, but a new error occurs at this moment. By the way, I upgrade my Ubuntu to 13.10 yesterday (anyway, if I cannot built it in 13.10, I will change back to 12.04).

qinjie@ubuntu:~$ apt-get source --build woo

Run the 'sudo apt-get build-dep woo' command again, that should fix the

    dpkg-checkbuilddeps: Unmet build dependencies: libqglviewer-qt4-dev | libqglviewer-dev

line. Then build again, it should work.
