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