Subject: [PATCH v2 2/2] benchtests: Building benchmarks as static executables
Date: Mon, 9 Aug 2021 07:16:59 -0700 [thread overview]
Message-ID: <20210809141659.2075052-3-hjl.tools@gmail.com> (raw)
In-Reply-To: <20210809141659.2075052-1-hjl.tools@gmail.com>
Building benchmarks as static executables:
=========================================
To build benchmarks as static executables, on the build system, run:
$ make STATIC-BENCHTESTS=yes bench-build
You can copy benchmark executables to another machine and run them
without copying the source nor build directories.
