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