Missing SONAME for libmkl_rt.so / 2019.0.4

[Goth__Sebastian]

Hey there,

the current version (2019.0.4) of libmkl_rt.so has no SONAME set. This leads to various minor linking issues, as ld/cmake then places the absolute path in the DT_NEEDED ELF field, instead of only "libmkl_rt.so". That again is a problem in deployments.

Would it be possible to get SONAME set to simply "libmkl_rt.so" in an upcoming version?

Probably it would be best to do it for all dynamic mkl libraries.

Currently only the following libs have a SONAME:

libiomp5_db.so
libiomp5.so
libiompstubs5.so
libmkl_vml_avx2.so
libmkl_vml_avx512_mic.so
libmkl_vml_avx512.so
libmkl_vml_avx.so
libmkl_vml_cmpt.so
libmkl_vml_def.so
libmkl_vml_mc2.so
libmkl_vml_mc3.so
libmkl_vml_mc.so

If there is a better way to express this request for the free edition of MKL, please tell me.

Thanks,
Sebastian

actually libiomp*.so are part of the compiler, 

but you are right, objdupmped the latest 2019.4 shared objects and see we broken to add soname 

]$ objdump -p *.so | grep SONAME
  SONAME               libmkl_vml_avx2.so
  SONAME               libmkl_vml_avx512_mic.so
  SONAME               libmkl_vml_avx512.so
  SONAME               libmkl_vml_avx.so
  SONAME               libmkl_vml_cmpt.so
  SONAME               libmkl_vml_def.so
  SONAME               libmkl_vml_mc2.so
  SONAME               libmkl_vml_mc3.so
  SONAME               libmkl_vml_mc.so
Probably, we will try to resore this option in the future versions of mkl.

I have a similar comment based on automated QC done by Gentoo Linux. also, you should include version numbers in the lib-foo*.${ver}.so and then make symbolic links from lib-foo*.so, etc.

ok, thanks for the additional info. Meantime, I would recommend you submit the issue into Intel Online Service Center.

[Gennady_F_Intel]

Could you check the latest version of MKL 2020 update 2 which available for downloading and it contains the fix of the issue?
