scons install release=1\r

+However, if you specifically only want to build certain architectures, you can provide a comma separated list of the required architectures to the targetArchitectures variable on the commandline, like so:\r
+scons targetArchitectures=x86\r
+or\r
+scons targetArchitectures=x86_64\r
+or\r
+scons targetArchitectures=x86,x86_64\r
