Summary0015482: CUDA - Support Static Linked Binaries.
Descriptioncurrently FindCUDA searches for "cudart" and other CUDA equivalent libraries.
These find the dynamic versions of the files, as they are named libcudart.so libcudart.dylib.... etc.

It seems to be impossible to compile with the static files named "libcudart_static.a"

One could set the CUDA_*_LIBRARY cache entries explicitly to refer to the static libraries.

I do have a pending change that enables this feature. I've been testing it and need to find some time to integrate it.

Im overriding the variable as a temporary solution, but i have to switch based on the OS as I can't see an easy way to get access to the /lib or /lib64 variable.

James, Thanks for the awesome Module!

I had some ordering wrong when i first tested my "work around" when i actually overrisde the library using this:

find_package(CUDA)
get_filename_component(CUDA_LIB_FOLDER ${CUDA_LIBRARIES} DIRECTORY)

unset(CUDA_LIBRARIES)
set(CUDA_LIBRARIES "${CUDA_LIB_FOLDER}/libcudart_static.a")

message("Using static lib: " ${CUDA_LIBRARIES})

i can see this in the build log:
Using static lib: /usr/local/cuda/lib/libcudart_static.a

But when i go to actually run the binary i get this message:

 CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

Process finished with exit code 1

NOTE: I just made a quick sample out of the deviceQuery CUDA sample source.

James,
Is there any way you could post / point me to you patch that has this support. I could at least then bundle it into the project Im working on.

I could give you a copy of the FindCUDA that has these changes, but there are a few other changes in there that would need to be removed to make it work for you.

Do you have the ability to use a custom FindCUDA?

Curtis Mahieu   
2015-03-31 15:24   
yeah i can use a custom findCUDA.

I just teased it apart. You can find a copy in stage:

Awesome! Thanks!

Ill test it out today.

What platforms have you tried? I developed this for Windows, Linux, and Mac.
