Cheers,
Good tips! Another good one is: If the build is crashing at the linking step due to not enough memory, then something that can help _a lot_ is reducing the size of the object files by removing debug info from them. You can pass in the CXXFLAGS environment variable the "-g1" flag to reduce the debug info that goes into the object files (or even "-g0" to not have any debug info at all inside them). Note: Is recommended to start a new clean build from scratch if you modify the value passed in the CXXFLAGS environment variable to the build.
