CentOS Linux Configure Script Error – No package ‘libdaemon’ found

While running a configure script before compiling an application on CentOS Linux I received an error regarding libdaemon which caused the configure script to fail. Using YUM I was able to list the available packages that included libdaemon in the name, install one, and then move past that error in the configure script. Below I show how to list packages using YUM with libdaemon in the name and then show example output of installing libdaemon-devel which is the package needed by the configure script.

Install Or Upgrade One Application From coreutils Package On CentOS Linux

Yesterday I needed to upgrade a single application on CentOS Linux. First I figured out that the application was part of the coreutils RPM package which is currently only available up to version coreutils 5.97-23 on CentOS. The current coreutils package is already up to coreutils 8.5 and upgrading coreutils is near impossible on CentOS because of other package requirements that it needs. Below are instructions on how to download the coreutils source, build the coreutils applications in a new directory, and then upgrade one application.

Configure: error: Your operating system’s lex is insufficient to compile libpcap

This morning I was attempting to upgrade libpcap on a Cent OS server to a newer version.  I decided to get the newest version of libpcap from git.

When running the configure script I received the following error:

bash

  1. checking for flex... no
  2. checking for bison... no
  3. checking for capable lex... insufficient
  4. configure: error: Your operating system's lex is insufficient to compile
  5. libpcap.  flex is a lex replacement that has many advantages, including
  6. being able to compile libpcap.  For more information, see

Configure Evernote For Offline Access on iPhone or iPod Touch Via IMAP

I recently started using Evernote to store all of the notes I take on a daily basis across plarforms. Evernote allows me to take notes and sync between numerous computers, my T-Mobile Blackberry Curve, and my iPod Touch. One thing that Evernote lacks is a solid method for accessing my notes when I am out of range of an Internet connection. I was pleased to learn that you can actually access your notes offline via IMAP and even though it is not ideal its good enough for now since every other part of Evernote is top notch.
