Linker issue with YOLO CUDA 8.0 API libraries in c files

Re: Linker issue with CUDA API libraries

mrjj

Hi and welcome to the forums

Does link come with question ?

if using C++, you might need to wrap the includes in
extern "C" {
#include "xxx.h"
}

But else you must tell a bit more about what issue is , what you tried, the
error messages you get etc. The compiler you use.

else the link shows how to link to the libs.

slman_alii

the problem is with functions that defined in cu file and used in c file.
sorry my question isn't clear enough

SGaist

Hi,

Then please show the exact error you are getting.

What does your .pro file look like ?

Did you just take all the files of the project and put them in your project ?
