For this little jaunt we'll need to download the SVN source as the vanilla 0.9.10 source release would not compile under Fedora (at least not for me). It's easy to do, just follow the below commands. In addition you'll need your basic build environment such as c++ compilers, make and what not.
Start off by installing Desmume's dependencies (one command):
sudo yum install svn SDL* gtk2-devel glade-devel soundtouch-devel mesa-libOSMesa-devel agg-devel gtkglext-devel lua-devel intltoolNext off we'll want to download the source from Desmume's SVN repository (one command):
svn co https://desmume.svn.sourceforge.net/svnroot/desmume/trunk/desmume desmumeNow lets cd into the Desmume directory, which contains the source code (one command):
OK, still with me? This is the part where the magic happens... the compile! (3 commands):
CXXFLAGS='-O2 -march=native -mfpmath=sse' ./configure --prefix=/usr
makeOnce the make finishes you'll want to install your baby into it's final resting place. (one command):
sudo make installAnd there you have it. A fresh steaming pile of Nintendo DS emulator. Load up a game ROM (one you legally own, of course) and give it a shot!
