A Simple Makefile for a GTK/GTKMM Project

By Anonymous
When compiling small applications, its fairly easy just to compile using g++ from the command line. If you’re compiling anything more complex than a single file, its probably easier to use a Makefile. This example Makefile demonstrates how to compile an application that uses the GTKMM library. NAME=my-app CFLAGS=-g -Wall -o $(NAME) GTKFLAGS=`pkg-config --cflags --libs gtkmm-3.0` SRCS=main.cc myapp.cc CC=g++ # Do all all: main # Compile main: $(SRCS) $(CC) $(CFLAGS) $(SRCS) $(GTKFLAGS) # Clean clean: rm -f $(NAME) rm -f *.h~ rm -f *.cc~ rm -f Makefile~ rm -f *.glade~

Changing Default Search Provider in Firefox on Linux Mint

By
On Linux Mint, the default version of Firefox is installed and configured to allow the following search engines to be queried directly from the address bar: Yahoo! Startpage DuckDuckGo Wikipedia Mint defines these as the default available set of search engines based upon 3 criteria (funding to Linux Mint, privacy support and whether the search engine is non-commercial). Other search engines such as Google, Bing or Twitter, etc. can easily be added into the default version of Firefox however. To add a different search provider, browse to Search Engines At the bottom of the page, click on the icon of the requested search engine, then click on the ... button in the URL bar and select the Add Search Engine option.
