colorgcc – Color your compiler output on Fedora

Lets start with installing colorgcc :

sudo yum install colorgcc

Now once that is done, you will need to ensure that the call to g++, gcc and others that you want to use, you will need to create a link in the “~/bin” directory, like so:

for i in g++ gcc c++ cc 
do
    ln -s $(which colorgcc) ~/bin/$i
done

The one liner above will create the links for colorgcc as your favourite compiler in your homedir. Don’t forget to add the bin diretory to your PATH variable:

export PATH=~/bin:$PATH

And now finally the ~/.colorgccrc file taken from Ubuntu for your reference:

#
# colorgcc configuration file
#
# $Id: colorgccrc,v 1.1.1.1 1999/04/25 15:24:03 jamoyers Exp $
#
# This file should be named $HOME/.colorgccrc
#
#
# The following groups of attributes may be combined for a given color:
#
# clear         black      on_black
# reset            red        on_red
# bold            green      on_green
# underline     yellow     on_yellow
# underscore    blue       on_blue
# blink            magenta    on_magenta
# reverse       cyan       on_cyan
# concealed     white      on_white
#
# For example, srcColor: bold cyan on_yellow
#

# gccVersion: if defined, append "-" to the compiler paths
# defined hereunder. Otherwise, those paths remains as is set
# gccVersion: 4.1.1

# Define the paths to the actual location of the various compilers.
# (Currently, colorgcc only understands these: g++ gcc c++ cc g77 f77 gcj)
g++: /usr/bin/g++
gcc: /usr/bin/gcc
c++: /usr/bin/g++
cc:  /usr/bin/gcc
#g77: /usr/bin/g77
#f77: /usr/bin/g77
#gcj: /usr/bin/gcj

# Don't do color if our terminal type ($TERM) is one of these.
# (List all terminal types on one line, seperated by whitespace.)
nocolor: dumb emacs

# Text between ` and ' is usually source code.
srcColor: bold cyan

# Text other than a warning or error.
introColor: reset

# Warnings and errors both have similar formats:
#    filename:999:Message
# Each field may be assigned a different color.

# Warnings
warningFileNameColor: reset
warningNumberColor:   blue
warningMessageColor:  yellow

# Errors
errorFileNameColor: reset
errorNumberColor:   blue
errorMessageColor:  bold red

# Possible translations, if you use localized compiler.
# (List all translations on one line, seperated by whitespace.)

Installing Full Blin g theme on N900

I was going through the post : http://talk.maemo.org/showthread.php?t=46739
and found the theme quite intruging but not complete to the point where I can download the deb file and install it in /usr/share/theme/ dir with simple commands “apt-get” or at max just use mkdir command to create the dir and dump everything in that dir. So, I wrote this couple of bash one liners to copy the required files to my N900.
