link cuda with gmp

cuda, gmp

Solution

The GMP library is compiled for the host, and so it can't be used directly in device code. That is the direct reason for the error you are seeing.

Since it's an open-source library, it might be possible with some effort to go through the code and create your own version, that has appropriate `__device__` decorators (and possibly other changes) to the various functions you need. This would probably require a substantial amount of work, however.

Another alternative might be to investigate the CUMP library.

Another alternative might be to investigate the xmp library

Another alternative might be to investigate the campary library

Problem

I am trying to use cuda with the GNU multiple precision library (gmp). When I add gmp instructions like mpf_init() to my device code I get this compiler error: tlgmp.cu(37): error: calling a host function("__ gmpf_init") from a __ device__ /__ global__ function("histo") is not allowed. Is it possible to redefine gmp instructions so that they can can be used in device code?
