  28 To build a version of statetrace suitable to run on a particular ISA, use a
  29 target of the form build/<arch>/statetrace. For example, to build statetrace
  30 for ARM binaries, run:
  31
  32 scons build/arm/statetrace
  33
  34 You may need a cross compiler in order to build statetrace successfully. To
  35 specify an alternative compiler, set the CXX scons argument on the command
  36 line. The CXX environment variable is NOT considered when selecting the
  37 compiler. To override the compiler for a particular target ISA, set the
  38 <arch>CXX scons argument. For example, to build both the AMD64 version and
  39 the ARM version at the same time using the system compiler for the AMD64
  40 version and a cross compiler for arm, your command line would look like the
  41 following:
  42
  43 scons ARMCXX=arm-cross-g++ build/amd64/statetrace build/arm/statetrace
  44
  45 After a successful build, the statetrace binary(binaries) will be located in
  46 the build/<arch>/ directories you specified on the command line.
