<p><b>unused parameter ‘fplog’ [-Wunused-parameter]</b></p></div></div></div></blockquote></div></div></blockquote><div>The problem is that for gcc 4.8, -Wno-unused-parameter (and various others) is only added to the C compilation flags, but nvcc gets its flags from the C++ flags. So these warnings are not silenced in CUDA code when compiling with gcc 4.8.</div>
<div><br></div><div>The reason why it has started occurring now is that previously, the gcc 4.8 build on the GPU host was built with GMX_GPU=OFF, but it has now been changed to build with CUDA 5.5. You can see this if you compare a successful build and a failing build for one of the affected patches.</div>
