Hi,

I'm trying to compile a program to use blas lib on k2hevm but I get these linking errors:

The blas lib files are those come with MCSDK, and I'm compiling these files locally on MCSDK_linux. I've compiled other files successfully without the blas lib. So would anyone please provide any idea on solving this?

Thanks,

Shang

    I figure I need to rebuild the lib to target to arm?

    Shang Li,

    The BLAS lib support is available in MCSDK-HPC package. Moving this thread over HPC forum for appropriate and faster response.

    Thank you.

    The MCSDK HPC user guide is available: processors.wiki.ti.com/.../MCSDK_HPC_3.x_Getting_Started_Guide

    When we compile the BLAS inside HPC package, we didn't have any error:
