use roi_pooling question

[l35633]

hi! thank you !
I compiled roi_pooling.so using nvcc8.0 in CUDA8.0. It works fine in faster-rcnn.
I coped it to this project as shown.
But something is wrong as below:
ImportError: /mnt/hgfs/DeepLesion/Code/CADLab-master/CADLab-master/LesaNet/roi_pooling/_ext/roi_pooling/_roi_pooling.so: undefined symbol: state

would you please give some advices and directions?
Thank you very much!
