[petsc-users] Unable to configure PETSc with CUDA: Problem with thrust directory

[Dominic Meiser]

Can you try configuring with

--with-thrust-dir=/usr/local/cuda-6.0/include

I.e. omit the 'thrust' at the end of the path. Probably you'll need the 
same fix with cusp:

--with-cusp-dir=/usr/local/cuda-6.0/include

Cheers,
Dominic
