Patch [1] caused building util/m5 to fail due to the flag was not an option in the SConstruct file. It is apparently the case for other programs in util/ relying on scons. This patch fixes the above problem, and also adheres to the default behavior introduced by [2]. [1] This patch introduced the "--no-duplicate-sources" flag to the scons build in util/ https://gem5-review.googlesource.com/c/public/gem5/+/68518 [2] This patch turns this flag off by default, https://gem5-review.googlesource.com/c/public/gem5/+/69717 Change-Id: I51376f7b3bf06438b7bc7ff84bc599deecac5bd1 Signed-off-by: Hoa Nguyen <hoanguyen@ucdavis.edu> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/69797 Maintainer: Bobby Bruce <bbruce@ucdavis.edu> Reviewed-by: Alex Richardson <alexrichardson@google.com> Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Ayaz Akram <yazakram@ucdavis.edu>

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.
