303358Srdreslin@umich.eduTo build a version of statetrace suitable to run on a particular ISA, use a
311516SN/Atarget of the form build/<arch>/statetrace. For example, to build statetrace
326654Snate@binkert.orgfor ARM binaries, run:
336654Snate@binkert.org
346654Snate@binkert.orgscons build/arm/statetrace
356654Snate@binkert.org
363358Srdreslin@umich.eduYou may need a cross compiler in order to build statetrace successfully. To
373358Srdreslin@umich.eduspecify an alternative compiler, set the CXX scons argument on the command
386654Snate@binkert.orgline. The CXX environment variable is NOT considered when selecting the 
396654Snate@binkert.orgcompiler. To override the compiler for a particular target ISA, set the
401516SN/A<arch>CXX scons argument. For example, to build both the AMD64 version and
413358Srdreslin@umich.eduthe ARM version at the same time using the system compiler for the AMD64
423358Srdreslin@umich.eduversion and a cross compiler for arm, your command line would look like the
433358Srdreslin@umich.edufollowing:
443358Srdreslin@umich.edu
453358Srdreslin@umich.eduscons ARMCXX=arm-cross-g++ build/amd64/statetrace build/arm/statetrace
463358Srdreslin@umich.edu
473358Srdreslin@umich.eduAfter a successful build, the statetrace binary(binaries) will be located in
483358Srdreslin@umich.eduthe build/<arch>/ directories you specified on the command line.
