Toolchain script finds "openblas-0.3.5.tar.gz" yet tries to unpack "OpenBLAS-0.3.5.tar.gz", causing an error

[David Gunter]

From the latest git repo, I run the toolchain script to install the third party tools and libraries. I'm on a cluster that is blocked from using wget, curl, etc. so I have to download all the packages manually and place them in the ./build/ directory. This is fine until script/get_openblas_arch.sh is called. It successfully finds openblas-0.3.5.tar.gz but errors when it tries to unpack it.  Here is the offending code. 

echo "==================== Getting proc arch info using OpenBLAS tools ===================="

# find existing openblas source dir

openblas_dir="$(find_openblas_dir)"

# if cannot find openblas source dir, try download one

if ! [ "$openblas_dir" ] ; then

    if [ -f openblas-${openblas_ver}.tar.gz ] ; then

        echo "openblas-${openblas_ver}.tar.gz is found"

    else

        download_pkg ${DOWNLOADER_FLAGS} ${openblas_sha256} \

                     https://github.com/xianyi/OpenBLAS/archive/v${openblas_ver}.tar.gz \

                     -o OpenBLAS-${openblas_ver}.tar.gz

    fi

    tar -xzf OpenBLAS-${openblas_ver}.tar.gz

    openblas_dir="$(find_openblas_dir)"

fi

The fix is easy enough, just replace "OpenBLAS" with "openblas" everywhere.

Hi David,

when we started we pulled the OpenBLAS Tarball from Sourceforge where it
is actually named OpenBLAS-0.3.5... this is why we decided to still use
the name OpenBLAS-0.3.5.tar.gz when referring to the OpenBLAS Tarball.

When downloading the things manually as you do, the solution is to
simply rename the downloaded archive to OpenBLAS-0.3.5.tar.gz instead.

Best,
Tiziano
