Segmentation fault compiling CUDA "hello, world" with relocatable-device-code

Question

I'm trying my hand at using the relocatable-device-code flag. I have a large project that would be easier to maintain with small blocks of code.

I was able to get the project to compile. When trying to run it, I get a hard crash. When using the debugger:

(gdb) where #0 0x0000000000000001 in ?? () #1 0x00007fffffffe39c in ?? () #2 0x0000000000000000 in ?? ()

I've never seen a stack trace like that! I then reduced the amount of code until I came down to a singularity: main.cu file contains only

#include <iostream> int main(void) { std::cout << "hello, world" << std::endl; return 0; }

Which still fails. I'm using the following flags to compile my main.cu file.

nvcc -shared -rdc=true -arch=sm_20 -Xcompiler -fPIC -g -G

Do these make sense? Why the segmentation fault for such a simple progam?

Remove the -shared switch. That option is not applicable when you are trying to generate an executable.

Generate a shared library during linking. Note: when other linker options are required for controlling dll generation, use option -Xlinker.
