You need to get more error messages to diagnose this. I don't have a gcc installation on my development machine so can't check this. If you look in buildall.py you'll be able to see which flags give you the messages you need. I think you need -v (verbose)>

@GeorgeOnwubuya There should be a log file created (in the logs directory by default I think). If you can post that is should have more information.

from embench-iot.

from embench-iot.

@GeorgeOnwubuya OK - I see the issue. For GCC you need the -c flag to tell it to build an object file and not link. So you need to add --cflags=-c to your command line.

from embench-iot.

I added the --cflags=-c but I am still running into errors. I have posted the log file below

Am I missing other variables?

@GeorgeOnwubuya You are now getting link failures, and the errors indicate a problem with your C library setup. Here is the first example of the relevant message

/Users/user/Local/gcc_arm/gcc-arm-none-eabi-4_7-2013q3/bin/../lib/gcc/arm-none-eabi/4.7.4/../../../../arm-none-eabi/lib/libc.a(lib_a-exit.o): In function exit': exit.c:(.text.exit+0x2c): undefined reference to _exit'

So you do have a C library - it's finding exit in libc.a, but it is not finding _exit. This would normally be part of the libgloss board support package which is part of the newlib C library. Do you have a file libgloss.a in /Users/user/Local/gcc_arm/gcc-arm-none-eabi-4_7-2013q3/bin/../lib/gcc/arm-none-eabi/4.7.4/../../../../arm-none-eabi/lib?

I'm assigning to @PaoloS02 since he has most recently built the Arm target, in case there is something else needed for Arm.

from embench-iot.

It doesn't look like I have the libgloss.a file but I do have libgloss-linux.a file.
How do I get this file installed on my end? Is there a package I need to install?

Thanks for all your help.

from embench-iot.

Hello @GeorgeOnwubuya ,
one thing that I see at a first glance is that you need to include the math library. You can use the --user-libs option from the build_all.py script. So you need to add --user-libs="-lm" to your command line.
I'll come back to you as soon as I have checked the issue of the _exit symbol.

from embench-iot.

Hello @GeorgeOnwubuya ,
as we are in the context of embedded systems we need to specify how to enable the system calls.
With newlib come several sets of systemcalls that are enabled with the --specs options:

arm-none-eabi-gcc --specs=rdimon.specs
arm-none-eabi-gcc --specs=nosys.specs

rdimon provides syscalls that rely on semihosting. Nosys instead provides a set of stubs that retarget the system calls.
We usually use nosys.
In this case for instance you need to add the linker option:

--ldflags='--specs=nosys.specs'

Hope this helps.
Paolo

from embench-iot.

Thanks for your speedy reply Paolo.

It looks like I don't have the nosys.specs in my gcc directory. Any thought on how to get this pacakge?

Hi @GeorgeOnwubuya ,

Ok, you could try to look for nosys under your library folders like /Users/lib/arm-none-eabi. I'm not sure where it should be on your system, but it should contain it. Just if you want to make sure you haven't got it there while maybe defaulting to another installed toolchain by mistake.

Anyway if I'm correct that toolchain has been installed as a packet for your system, right? Usually in order to have a better control on what libraries you are using and what you are including, but above all in order to have control on the configuration of your toolchain and change it if necessary I'd suggest building gcc from scratch. If you want to have a look at the configuration we used for gcc to produce our results you can look here: https://github.com/embench/embench-iot-results
Every set of results has the full configuration for gcc, binutils and newlib.
@jeremybennett have we got somewhere to share the script we used to build our toolchains?

In the meantime you could also try to install a newer version of your arm toolchain (if it was installed as a packet). I've read here: https://trac.macports.org/ticket/57572 that they had a similar problem and fixed it with a patch. They switched then to gcc 9.2.
I'm not sure whether that's where your toolchain comes from, but its a guess.

Best,
Paolo

I had to donwload a more up to date version of gcc-arm-none-eabi. I have sucessfully built the benchmarks:

aha-mont64
crc32
cubic
edn
huffbench
matmult-int
minver
nbody
nettle-aes
nettle-sha256
nsichneu
picojpeg
qrduino
sglib-combined
slre
st
statemate
ud
wikisort
All benchmarks built successfully

I do have a few more questions.
-> How do I run the benchmarks? I know you can run them with respect to speed and size. I am just curious as to what the minimum configuration looks like.
-> Is there a way to run a single benchmark at a time?

Thanks,
George O.

from embench-iot.

Hello @GeorgeOnwubuya ,
once you built the tests you need to run benchmark_size.py for size results and benchmark_speed.py for speed results.
If you invoke them without arguments you'll see the required options. The size script doesn't need options, but you might want anyway to have a look at them in order to decide at least whether to have absolute results or results relative to the baseline.

The speed script instead requires that you at least pass a target module. These are the python modules in pylib/. Each of these modules describes a debug session that needs to interface with real hardware or at least emulated hardware (e.g. ri5cy verilated model).

Have a look at the results repo to have an idea of what kind of options we usually use for the tests: https://github.com/embench/embench-iot-results

You'll find also how we ran the baseline that I mentioned earlier, that is the sets of results against which the scripts calculate the relative data: https://github.com/embench/embench-iot-results/blob/master/details/cortexm4-armv7m-gcc-9.2-o2.mediawiki

Hope this helps.

Thanks @PaoloS02.
I ran the benchmark_size.py and I am running into the error pasted below.

Traceback (most recent call last):
File "benchmark_size.py", line 24, in
from elftools.elf.elffile import ELFFile
ModuleNotFoundError: No module named 'elftools'

Where do I find the module named 'elftools?

from embench-iot.

Hi @GeorgeOnwubuya

you probably need to install pyelftools if you haven't got it already.
Does this work?

pip3 install pyelftools

Let me know
Paolo

from embench-iot.

@PaoloS02 I've marked as an enhancement, to allow you to update the documentation in the light of @GeorgeOnwubuya experience.
