Linux kernel is 2. GCC version number is 4. Your configuration may be different from mine but the installation steps below should work fine for most configurations with little or no change at all including other Linux distributions and even unixes e. MacOS X. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress 1 and in the GIF image format, the compression method currently used in zlib essentially never expands the data.
LZW can double or triple the file size in extreme cases. Before starting, please check to see if there is a latest version available to download. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search.
I'm completely new to Ubuntu. I got installed it because my school uses a lot of Linux type stuff in my school's Computer Science program so I figured I would use Ubuntu on my own machine and just do my code from there instead of the computer labs. However, I'm having a lot of trouble trying to install the numerous packages that aren't included natively on Ubuntu.
Can someone help me install the PNG library, libpng and zlib. This is just one of many things I need to get on here but I think I need to first start off with this. I did download both packages, did the tar xf thingy on the download, and looked at the README files for insight on installing the software. I get weird errors though. I first tried installing libpng and the terminal was like zlib isn't installed so I was like ok, I'll just get zlib but permission is denied.
Do I need to get root or something? I remember seeing people say root before, but I don't know if it is relevant. I'm really new so I don't understand a lot of these things and it's kinda scary. Please help. Ubuntu uses a thing called apt , which is a package manager.
