From: Luis Quesada on 13 Apr 2010 17:02 Dear all, I am getting an "expected string without null bytes" error when using cxfreeze for creating a standalone application (in Linux-Ubuntu). None of my files has null bytes. I also tried pyinstaller but I got the error attached at the end. My program runs fine when executed from eclipse. What is the easiest way of creating a standalone application? Is there a way of creating the executable file from eclipse/pydev?

Why bother? Every decent Linux system will have Python available. Why not just distribute it as a script?

Well every decent Linux system will have Java available too but it is still preferable to distribute jar files. The point is that I don't want to force my users to install all the packages that I had to install. Cheers, Luis

Every decent Linux system will have Python available. Why not > just distribute it as a script? I keep hearing this reply every time I ask this question, and it doesn't seem to make sense to me. Anything other than a trivial script will have dependencies. These might be other Python packages, C-extensions, and other libraries. What if your program runs on a version of Python other than the one installed on the client's Linux system? In my opinion, there is a severe need for this question to be answered in a robust and simple way. Is creating an rpm / deb file the answer? I don't know, but I think it's a very valid question. |
