Installing / compiling / running kdemo...how to? Ubuntu 12.10

Hi,

The kdemo uses the build.py script in the package, so running ./build.py should work. See the INSTALL file for more information.

Running ./build.py as in the INSTALL instructions produces this output in Ubuntu 12.10:

Traceback (most recent call last):
  File "./build.py", line 22, in <module>
    sdl_cflags = [subprocess.check_output(['sdl-config', '--cflags']).split()]
  File "/usr/lib/python2.7/subprocess.py", line 537, in check_output
    process = Popen(stdout=PIPE, *popenargs, **kwargs)
  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

You received this question notification because you asked the question.

Am I being a dumb ass here? I guess I should install Python first. I just done a thinko, or is that a usero. Doh!

I just installed Python 3.3 and I get the same output from ./build.py

Hmm, do you have libsdl1.2-dev installed?

No, libsdl1.2-dev (or any of the associated packages) were not installed. Once that was installed, then ./build.py seemed to work.

Upon running ./demo I get the following error:

./demo: error while loading shared libraries: libkunquat.so.0: cannot open shared object file: No such file or directory

I have checked that these are both installed from the Requirements, and they do seem to be installed fine.

SDL 1.2 (libsdl1.2-dev in Ubuntu)
OpenGL (libgl1-mesa-dev in Ubuntu)

The only variable as I can see is that I'm using Python 3.3 and the Requirements call for Python 2.7.

Okay, I solved it.

I forgot to run kunquat first using:

export LD_LIBRARY_PATH=~/kunquat/lib
export PYTHONPATH=~/kunquat/lib/python2.7/site-packages
~/kunquat/bin/kunquat-tracker ~/kunquat/share/doc/kunquat/examples/example.kqt.bz2

Thanks all is working now.
