undefined reference to GOMP_parallel

Hi I am getting this error while building openBLAS-

Failed to build OpenBLAS

Any suggestions?

In this project, we use OpenBLAS v0.2.18.

Thanks.
I am building the same OpenBLAS v0.2.18 as given by caffe-android-lib project. But while making it generates this libopenblas_armv8p-r0.2.20.dev.a file.
I couldn't figure out where I am getting wrong here.

Then I think you should create an issue in https://github.com/xianyi/OpenBLAS instead of here.
Thanks.
