2013-09-08 21:03:51 -0600 | answered a question | opencv(2.4.6.1) compiled with cuda (5.5): can't compile cpu based codes Solved. The only thing I did after posting the above (ad after a weekend away from it) was to search and locate all the libraries related to CUDA. On my 64bits system and OS (linux ubuntu 13.04) they are in So appending the above line to followed by did the trick. Simply had omitted this (it actually wasn't explicit in the installation guide I had followed). Now CPU examples I could compile can be executed. |

2013-09-05 20:29:02 -0600 | asked a question | opencv(2.4.6.1) compiled with cuda (5.5): can't compile cpu based codes Hi, I'm on ubuntu 13.04, have successfully compiled opencv 2.4.6.1 with the latest cuda 5.5. At least I thought it was a success. Because when I try to compile the examples in /opencv-2.4.6.1/samples/c, all I get is: And all the consequences of the above: This being my first use of cuda and compilation with opencv, I don't know where to go from this. The only libnppc.so.5.5 I have found was for linux suse. Is there any thing I didn't set up properly when installing cuda (did with the .deb packages from nvidia site)? Cuda examples compile properly, opencv compiled and installed without any error. Edit: I've just tried to compile an example (houghlines.cpp) in the gpu section of the samples (opencv-2.4.6.1/samples/), with: and it compiled and I could run the program all right. The above problem with libnppc remains with cpu examples (such as those in samples/c and samples/cpp) and any other older program I wrote... |
