leezu opened a new issue #18255:
URL: https://github.com/apache/incubator-mxnet/issues/18255
## Description
If we compile mxnet via `cmake -GNinja -DUSE_MKLDNN=0
-DMKL_USE_STATIC_LIBS=0 -DUSE_CUDA=0 ..; ninja`, running an operation that
requires MKL will cause termination.
### Error Message
```
INTEL MKL ERROR: /opt/intel/mkl/lib/intel64/libmkl_vml_avx512.so: undefined
symbol: mkl_lapack_dspevd.
Intel MKL FATAL ERROR: cannot load libmkl_vml_avx512.so or libmkl_vml_def.so.
terminate called without an active exception
```
## To Reproduce
`python3 -c 'import mxnet as mx;
print(mx.nd.square(mx.nd.random.uniform(shape=(1024,))))'`
## Discussion
The missing symbol is defined in
`/opt/intel/mkl/lib/intel64/libmkl_core.so`: `000000000095ad00 T
mkl_lapack_dspevd`. `libmxnet.so` does depend on `libmkl_core.so`:
```
% ldd libmxnet.so
[...]
libmkl_intel_lp64.so =>
/opt/intel/mkl/lib/intel64/libmkl_intel_lp64.so (0x00007fe082883000)
libmkl_intel_thread.so =>
/opt/intel/mkl/lib/intel64/libmkl_intel_thread.so (0x00007fe080317000)
libmkl_core.so => /opt/intel/mkl/lib/intel64/libmkl_core.so
(0x00007fe07bff7000)
[...]
```
Thus it's unclear why MKL complains that the symbol is missing when
attempting to dlopen `libmkl_vml_avx512.so`
