Hi everybody,

First of all I appology for my english level ^^

Being new user of GPU programming, i started following all steps to install CUDA and i could use it with the Samples programs proposed with the installation…

But trying to compile my algorithm (coded on Code::Blocks under Ubuntu) that uses Lemon libraries, Thread and mutex libraries aswell (handled by c++11) I started having some weird errors…

I tried changing the IDE and use Nsight … and even try by changing makefiles and try to copy configuration on a sample but no way to make the algorithm work even by not using yet CUDA …

Here you can see the errors I get:
