mkl_def.so is not found in Intel MKL library 2019

mkl_def.so is not found in Intel MKL library 2019 or 2020 for linux 32 bit. We have been using using Intel MKL library an older version ( a very old version released sometime in 2012 ) and now trying to upgrade it to latest one. We are finding issue on Linux 32 bit as getting compilation error mkl_def.so ( gcc 6.3 C++ ). We checked and found that the file mkl_def.so is included in Linux 64 bit package but not in Linux 32 bit package of intel MKL. Please suggest how to fix the issue

Could you show us how do you link your application on ia32 based system?

Could you please let us know that why you guys have removed libmkl_def.so from ia32 ?

We have followed the Intel link line advisor to link our application in 32bit.

it is some kind of renaming:

for ia32 IA: libmkl_p4.so == libmkl_def.so ( the default for SSE@ enabled processors)

therefore your application should migrate to using the latest versions w/o a problem.

for intel64 - yes we provide the same library but with the libmkl_def.so name
