| 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 |
Steve Reinhardt | dc8018a | 2016-02-06 17:21:18 -0800 | [diff] [blame] | 36 | line. The CXX environment variable is NOT considered when selecting the |
Gabe Black | eab89a0 | 2011-03-02 22:53:11 -0800 | [diff] [blame] | 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. |
