Description

I tried to build MXNet(tag 1.6.0) from source,but failed each time after Running: OpWrapperGenerator.py.

Error Message

[ 93%] Built target mxnet
Running: OpWrapperGenerator.py

Segmentation fault: 11

make[2]: *** [cpp-package/CMakeFiles/cpp_package_op_h.dir/build.make:59: cpp-package/CMakeFiles/cpp_package_op_h] Error 255

Environment

Ubuntu 19.10, CUDA 10.2, OpenCV 4.2
gcc/g++ version is 7.4.0,build with c++14.
I chose USE_CPP_PACKAGE, set BLAS to MKL and CPU runtime to TBB.

What have you tried to solve it?

1.I switched BLAS from openblas to MKL because of issue #11543, but it doesn't work.

After switching to MKL, you may run into #17641

Can you try deleting 3rdparty/openmp to see if the segfault is due to conflict between llvm openmp and intel openmp?

You're right.Build finished after 3rdparty/openmp removed,.Thank you for your support!
