Error: unknown arch

[thotaraghava]

Hi anybody,

I was trying to run make to install toolchain for pulpino simulations and I end up by getting below error.

       configure: error: Unknown arch

Please help in this regard.

Thanks,

[thotaraghava]

Anybody knows this issue ??

[thotaraghava]

I am clueless on this issue.

Hi @thotaraghava, it seems to me that it might be a problem with your compiler, but you should post a more detailed log and write exactly what you are doing (including the platform you're running on).

[thotaraghava]

Thanks @FrancescoConti for your response. I am doing exactly the procedure mentioned in the below link. https://github.com/pulp-platform/ri5cy_gnu_toolchain

I am running make command to install toolchain.

I want to simulate PULPino core with testcases, for that I need to install toolchain.

Kindly help.

[FrancescoConti]

Ok. Can you provide a full log from when you type make up to the error?

Edit: Also, please let us know the platform you're running on (e.g. version of Ubuntu)

First two lines in make file I commented because, I we dont have access internet on VWP, so I downloaded separately and copied down to working area.

[thotaraghava]

I am running on LINUX environment.

[FrancescoConti]

Which distribution of Linux and which version?

[thotaraghava]

LSB_VERSION=base-4.0-amd64:base-4.0-ia32:base-4.0-noarch:core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch

Red Hat Enterprise Linux Server release 6.6 (Santiago)

Distributor ID: RedHatEnterpriseServer Release: 6.6

Is this info enough ? Let me know if you need any more information

[FrancescoConti]

Ok, can you also share the version of GCC (gcc --version)?

@FrancescoConti , please let me know your opinion.

Thanks

Initially I thought there was a problem with your setup, but actually the solution might be simpler. Can you check whether the version of the toolchain you downloaded from Berkeley is correct? You can do that by the following command:

cd toolchain
git rev-parse --short HEAD

The output must be d038d59. If not, then you have to redownload the correct version from their repo.

This is the one, I am getting. Then I should re-download I suppose. @FrancescoConti Below the one I should re-download right. https://github.com/riscv/riscv-gnu-toolchain

Re-downloading correct version means from the above link only right. I did the same. How could I make sure its correct version. Please suggest.

I understood. From the commented line in Makefile

cd toolchain && git checkout d038d596dc1d8e47ace22ab742cd40c2f22d659e,

your version suggested is matching with initial portion of above checkout version. Then, how can I make sure same version download in Windows as I dont have internet access to my VWP.

[thotaraghava]

@FrancescoConti , any update on this

[FrancescoConti]

If version d038d59 is in the history of their master branch (I don't know whether that is so), you can uncomment that line in the Makefile (or simply execute that same line in the shell).

On a side note, this really does not look like a problem with this project, so I'm going to flag the issue as closed.

Thank you.
