28To build a version of statetrace suitable to run on a particular ISA, use a
29target of the form build/<arch>/statetrace. For example, to build statetrace
30for ARM binaries, run:
31
32scons build/arm/statetrace
33
34You may need a cross compiler in order to build statetrace successfully. To
35specify an alternative compiler, set the CXX scons argument on the command
Steve Reinhardtdc8018a2016-02-06 17:21:18 -080036line. The CXX environment variable is NOT considered when selecting the
Gabe Blackeab89a02011-03-02 22:53:11 -080037compiler. 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
39the ARM version at the same time using the system compiler for the AMD64
40version and a cross compiler for arm, your command line would look like the
41following:
42
43scons ARMCXX=arm-cross-g++ build/amd64/statetrace build/arm/statetrace
44
45After a successful build, the statetrace binary(binaries) will be located in
46the build/<arch>/ directories you specified on the command line.
