Hi Aniruhd, Thanks for your response, but this issue was resolved by the addition of the following lines to common.mk which is located (as of the latest SDK version 3.0) under <SDK path>/C/common/
NVCCFLAGS := --compiler-options -fno-inline The PyCUDA issue was actually a matter of incorrect pathing! Yowsie!
