[okl4-developer] New to OKL4

Hi Yeonju,

Thanks for the quick reply!

You're right, I don't have Python 2.4 and that's causing the error. I've
installed Python 2.4 and symlinked /usr/bin/python from Python 2.5 to Python
2.4.

After that, I tried the build script and encountered the following:

Is installing OKL4 as straightforward as just running the build script?

Please advise.

Thanks in advance!

Cheers!
