Linking SDL2 with Nvidia cuda libraries

SDL Development
1

I can hear you already. Why would anyone want to do that!

I found a simple raytracing app that output images to png files created via a cuda raytrace routine.

I tried to add a SDL window so i could see the cuda generated images directly.

My first problem is the SDL2 headers have conflict with the CUDA headers. So I hand built my own SDL2 header (copying only what is necessary). I tested the customer header on a SDL2 hello world program and it worked!

I managed to get it to compile but it refuses to link with undefined references to all SDL2 functions.

g++ -Wall -Wextra -Ofast -m64 -o “tracecudasdl2” -Wl,–start-group “tmp/tmpxft_00004fe9_00000000-18_tracecudasdl2_dlink.o” “tmp/tmpxft_00004fe9_00000000-16_tracecudasdl2.o” -lSDL2 “-L/usr/local/cuda/bin/…//lib64/stubs” “-L/usr/local/cuda/bin/…//lib64” -lcudadevrt -lcudart_static -lrt -lpthread -ldl -Wl,–end-group

My environment:
Ubuntu 18.04
gcc 5.5
g++5.5
Cuda 8.0

Any ideas!

That is because you eviscerated the library. :upside_down_face:

Any ideas!

Use the normal SDL2 headers, not your copy&pasted one. What header conflicts do you have? What messages do the compiler output?

I get the following errors if I use the normal headers.

I have found this problem mentioned on the nvidia cuda forum but the usual context is in relation to conflicts with other third party packages and the usual resolution is make sure the third party packages doesn’t refer to the avx512vlintrin.h header.

They have also recommended some additional switches/options which I have tried but the implication is the third party package must be aware of those switches (SDL2 isn’t).

So if my hello world sdl2 program compiles and links and runs with my header and the cudasld2 program uses exactly the same functions and definitions and compiles without error why doesn’t it link?

The solution was to install gcc and g++ 4.8. The problem is version 5.5 of those.

So now I have cuda raytracing and SDL2 rendering. Nice!
