FindCUDA

Activates incremental builds for cutorch and cunn

How to use?

Make sure you have torch installed

Then do simply:

luarocks install findcuda

That's it! cutorch and cunn builds will now be incremental :-) It's a bit draft, so worst case if something is not building fully, just:

• (ideally) zip your cutorch directory, and send it to me somehow, so I can take a look
• rm -Rf build

How this source-code was obtained?

• downloaded https://cmake.org/files/v3.5/cmake-3.5.0-rc1.tar.gz
• extracted
• copied Modules/FindCUDA.cmake and Modules/FindCUDA/ folders
• applied a custom fix to allow incremental builds on cutorch, and cunn (might not generalize for other software)
• added appropriate rocks file and CMakeLists.txt so installable as luarocks module

FAQ

Why not just use the Ubuntu standard FindCUDA?

• doesnt contain the fix for incremental builds on cutorch

Why not just download the gz directly?

• doesnt contain the fix for incremental builds on cutorch

Why not push the fix upstream into cmake?

working on it :-) This repo might evolve appropriately as a function of this, or disappear eventually, as and when upstream is fixed, and a new version of cmake is available
