I have downloaded extreme tux racer as a .tar.xz on sourceforge.I performed tar xJF on the file, a directory was created, I entered it and there I performed ./configure. A list of Dependencies was displayed telling whether or not it was installed:  ikigai@ikigai-SATELLITE-L50D-B ~/Downloads/etr-0.7.1 $ ./configurechecking for a BSD-compatible install... /usr/bin/install -cchecking whether build environment is sane... yeschecking for a thread-safe mkdir -p... /bin/mkdir -pchecking for gawk... gawkchecking whether make sets $(MAKE)... yeschecking whether make supports nested variables... yeschecking build system type... x86_64-pc-linux-gnuchecking host system type... x86_64-pc-linux-gnuchecking for g++... g++checking whether the C++ compiler works... yeschecking for C++ compiler default output file name... a.outchecking for suffix of executables... checking whether we are cross compiling... nochecking for suffix of object files... ochecking whether we are using the GNU C++ compiler... yeschecking whether g++ accepts -g... yeschecking for style of include used by make...

Regarding the question of whether I have libc6-dev installed,I performed ldconfig -p | grep libc6-dev without any result, but when I perform ldconfig -p | grep libc6 there are a lot of lines containing this string displayed.I opened the package manager, but when I entered the term sfml I got about 30 different lines, for sfml-audio about 10. I do not know how to choose the right thing.I use Linux Mint 17.3 Rosa.
How do I install sfml-audio to build extreme tux racer?
