undefined reference to `__intel_skx_avx512_memcpy'

[qiang__gao]

hi everybody，

in debian os， I compiled  successfully by icc and get a so file in parallel_studio_xe_2018_update1_cluster_edition.

but when run the program and load so file compiled, the error occur just like the topic title.

Any clue on what is happening ?

thank you!

I don't know why you can't find that particular function, but you can prevent the compiler from converting copy loops into memcpy calls by adding the "-nolib-inline" option to the compile line.

It is defined in libirc* and libintlc.so.
