Is there a libxsmm.so in the build directory for libxsmm?

Regards, Freddie.

Yes , libxsmm.so is in the lib folder of the build directory.

I am using this command to link at the address the example folder of pyfr:
export PKG_CONFIG_PATH=/home/himanshi/pyfr-venv/libxsmm/lib/libxsmm.so

As noted in the install guide you want to set export PYFR_XSMM_LIBRARY_PATH=/path/to/libxsmm/lib/libxsmm.so Alternatively, you can install libxsmm to a directory on your library load path.

Please read the install guide! As noted there libxsmm must be compiled with STATIC=0 BLAS=0 CODE_BUF_MAXSIZE=262144.
