    <title>topic undefined symbol mkl_blas_avx2_cgemm_copyb_ext in Intel® oneAPI Math Kernel Library</title>
    <link>https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/undefined-symbol-mkl-blas-avx2-cgemm-copyb-ext/m-p/1048593#M21043</link>
    <description>&lt;P&gt;I have tried to embed MKL in a java application by embedding the static mkl libraries in a shared lib of mine and then opening that shared lib from the jni. However, I got a link error when I created the shared lib: the symbol mkl_blas_avx2_cgemm_copyb_ext was undefined. I have looked at the static libraries, and indeed, *all* static mkl libraries that have this symbol list them with 'U'. On the other hand, this symbol does not even appear in the shared libraries.&lt;/P&gt;

&lt;P&gt;So I'm wondering, why does this symbol appear only in the static libs and why is it not defined?&lt;/P&gt;

&lt;P&gt;Thanks,&lt;/P&gt;

&lt;P&gt;--Laci&lt;/P&gt;

&lt;P&gt;PS: The same issue occurs both in versions 11.2 and 11.3 (distributed with icc versions 2015.5 and 2016).&lt;/P&gt;</description>

      <description>&lt;P&gt;I have checked and see the similar symptoms. The issue is escalated.&lt;/P&gt;</description>
