BtScanner Compile Error: cc1: error: unrecognized command line option -Wimplicit-function-dec

While doing some testing this evening I ran into all sorts of errors when attempting to compile a new version of btscanner on Backtrack Linux 5 R3. Luckily it is super easy to resolve the error complaining about an unrecognized command named -Wimplicit-function-dec. This error will display when attempting to run “make” against an already configured (./configure) btscanner source. Below we output the error in more detail, explain how to resolve the error by editing the make file, and then display the compilation process moving past the error.

Error Compiling pwntcha On Backtrack Linux – image.c:28:5: error: #error No imaging library

While troubleshooting some issues with pwntcha which is installed by default on Backtrack Linux version 5 R3 I received some errors compiling pwntcha from source. The Imlib2 development files need to be installed before compiling pwntcha from source on Backtrack Linux 5 R3 or Ubuntu 10.04. Below I provide the output from the pwntcha compile errors as well as show the install command for the package that needs to be installed before pwntcha will compile without errors.

Snort Configure Error: ERROR! dnet header not found – CentOS Linux

Earlier when installing snort on a CentOS Linux server I ran into a configure error. The error related to the fact that libdnet was not located on the server and while it was installed I did not have the libdnet-devel package installed. Below is the sample output from the configure error, an expandable complete output of the configure error, and the yum command to install libdnet-devel to move past this error when installing snort.

Move Long Running Linux Process To Screen Session

Have a long running Linux process open in a SSH terminal window and need to shutdown your computer without killing it? I run into this on a regular basis and never spent the time looking into a solution but this past weekend I actually decided to look and came up with a cool solution called reptyr. The reptyr application allows you to open screen and migrate the process to the screen terminal and away from the terminal connection opened without screen. This allows you to detach from the window without killing the process. Below is a quick overview of installing reptyr and how to use it.

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.
