yafu doesn't build with CUDA enabled

[Happy5214]

I'm trying to build yafu with CUDA enabled, and I'm getting the following compile error:

gcc -g -DUSE_NFS -DHAVE_CUDA -O3 -fomit-frame-pointer -Wall  -I. -Iinclude -Itop/aprcl -I../gmp/include -I../../ecm/ecm/include/linux -I/usr/local/cuda-11.2/targets/x86_64-linux/include/ -c -o factor/qs/tdiv.o factor/qs/tdiv.c

This is CUDA-specific, as it's within a HAVE_CUDA block.

Sorry, the CUDA code in yafu is very old, didn't ever really work, and hasn't been maintained. In short, don't use it. I will remove at some point.

Note that this is separate from gpu-msieve or gpu-ecm... if you build those with GPU enabled I believe yafu will use them as normal. You don't have to include any kind of cuda directive to yafu builds to do so.

That solved the compilation issue (rather, just commenting out the compiler flag from the Makefile, since I still needed the library arguments), but I now have a couple of linking errors.Both are related to GMP-ECM, and I'm not even sure if the second is a yafu issue (though GMP-ECM itself built OK):

(Note: "make x" is a renamed "make x86_64", since I couldn't get that to run.)

Were you able to fix this issue? I'm trying to compile yafu with CUDA-msieve and CUDA-CGBN-ecm and I'm getting the same type of errors. I tried including the CGBN and CUDA directories in the Makefile but it made no difference.
