Hi,
I have installed ARM RAL version,23.04 on my Linux machine and successfully built static libraries for Release mode with Arm GNU Toolchain 12.2.Rel1 (arm-gnu-toolchain-12.2.rel1-x86_64-aarch64-none-linux-gnu.tar.xz) for targets NEON and SVE.I enabled build options ,-DBUILD_TESTING=On` and `-DBUILD_EXAMPLES=On. Python version installed on my machine is 3.8.10.and Linux, Perf tool version is perf version 5.15.87,required for running benchmarks.
After build,I installed ARMRAL libraries for 2 targets in 2 different installation folders.
Afterwords,I tried running benchmarks with command, make bench for 2 targets separately one by one but for each one I am getting errors like following for all benchmarks.....
If I direct o/p to file,JSON objects printed are like below indicating that benchmarks not ran at all.:--
{"name": "demodulation_qam256_8", "error": true, "ts": 304990550, "dur": 192588}{"name": "demodulation_qam256_31", "error": true, "ts": 305183343, "dur": 192250}{"name": "demodulation_qam256_32", "error": true, "ts": 305375812, "dur": 194988}
Since I am evaluating ARMRAL for my work and new to ARMRAL, could you kindly look into the error and help me to identify root cause(eg whether I m missing something/making some error) and fix the error soon?
It would help a lot.
Regards,
Pankaj K

Hi Chris,
Thanks for your reply.I am checking with my manager abt getting Arm system access or access to Cloud service for Arm-based Linux instance as you indicated.
1 issue I am still facing is following:--
As indicated in "Run tests" section of readme, since I am not developing on an AArch64 machine, I compiled to configure the library toprefix the tests with `qemu-aarch64` for NEON as follows to run the tests on my x86_64,ubuntu linux machine :--
cmake -DBUILD_TESTING=On -DARMRAL_TEST_RUNNER=qemu-aarch64 -DBUILD_EXAMPLES=On -DBUILD_SIMULATION=On -DCMAKE_INSTALL_PREFIX=/home/sitteam/PankajK/arm_lib_2304_install_neon_static_rel /home/sitteam/PankajK/arm-ran-acceleration-library-23.04 -DCMAKE_C_COMPILER=/home/sitteam/PankajK/arm_gnu_toolchain_12_2/arm-gnu-toolchain-12.2.rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-gcc -DCMAKE_CXX_COMPILER=/home/sitteam/PankajK/arm_gnu_toolchain_12_2/arm-gnu-toolchain-12.2.rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-g++
make check
------------------------------------------------------------------------------
But I got following error abt which I am unsure, I mean why qemu-aarch64 executable is not getting generated despite providing cmake option in bold as above? Requesting to provide pointers to debug/resolve this issue. .Also can you provide more info abt "Dynamo Rio"?

Hi there,
Unfortunately qemu-aarch64 is not distributed as part of ArmRAL. Instead please see https://www.qemu.org/ for instructions on how to download and build it for your machine.
qemu-aarch64
Once you have QEMU installed you should provide the full path to the qemu-aarch64 executable in the ARMRAL_TEST_RUNNER CMake variable. Alternatively, if you place qemu-aarch64 on your executable path you can set -DARMRAL_TEST_RUNNER=qemu-aarch64 as you did before.
ARMRAL_TEST_RUNNER
-DARMRAL_TEST_RUNNER=qemu-aarch64
