Cutorch doesn't build with the newest cuda. (cudaPointerAttributes)

LevitatingBusinessMan commented 3 years ago

On this line here: https://github.com/torch/cutorch/blob/master/init.c#L938 cutorch is trying to use a non-existing property of cudaPointerAttributes. This property already went deprecated in Cuda 10.

Do you have a solution for this?

Same problem for me init.c:938:34: error: 'struct cudaPointerAttributes' has no member named 'isManaged' lua_pushboolean(L, attributes.isManaged);

I get this error when I want to build and install with arch

Seems like somebody on the ArchLinux user repositories has found a temporary fix.

Replace .isManaged with .type == 3 (cudaMemoryType::cudaMemoryTypeManaged).

LevitatingBusinessMan commented 2 years ago

I applied a patch to the AUR package, I am not entirely sure if it will work properly in programs using cutorch_isManagedPtr but at least the program compiles again.

according to:

https://github.com/nagadomi/distro/issues/11#issuecomment-645686463

-    lua_pushboolean(L, attributes.isManaged);
+    lua_pushboolean(L, attributes.type == cudaMemoryTypeManaged);

LevitatingBusinessMan commented 2 years ago

@mw66 Yep that's exactly it. cudaMemoryTypeManaged should be a constant for 3.
