The ebuild fails to build with GCC 4.5.1. Reproducible: Always Steps to Reproduce: 1. Switch the system compiler to GCC 4.5.1. 2. emerge -1v =dev-util/nvidia-cuda-sdk-3.2 3. Watch it fail. I originally had this in a local overlay before the official Gentoo ebuild was available. I recently switched to GCC 4.5.1 and this package will not build. I thought it was my ebuild that was causing it, but I removed my ebuild from my local overlay to switch to the in-tree version and it does not build either way. # emerge --info

================================================================= Package Settings ================================================================= dev-util/nvidia-cuda-sdk-3.2 was built with the following: USE="cuda doc examples (multilib) opencl -debug"
The issue is with the nvidia nvcc compiler and is known upstream. Looking at the release notes, GCC-4.4.4 is the newest gcc that it plays well with. This is also an issue with earlier SDK versions. What fails to compile is the examples. Simply emerging it with USE="-examples" makes the error go away. Its either that or setting your system to use an earlier GCC, emerging the sdk, then setting it back to GCC-4.5.x. Note that what fails is the inclusion of stl or other complex headers in .cu files. Development for CUDA under GCC 4.5.x still works well, solong as you keep the .cu source file as header free as possible.
Confirmed that nvidia-cuda-sdk emerges successfully with USE="examples" using =sys-devel/gcc-4.4.3-r3. gcc 4.4.4 is not tested but suspected to be working as well. [ebuild R ] dev-util/nvidia-cuda-sdk-3.2 USE="cuda doc examples opencl -debug" 0 kB Also confirmed that nvidia-cuda-sdk emerges successfully with USE="-examples" using =sys-devel/gcc-4.5.1-r1. [ebuild R ] dev-util/nvidia-cuda-sdk-3.2 USE="cuda doc -examples opencl -debug" 0 kB
Created attachment 256254 [details] Ebuild for nvidia-cuda-sdk-3.2 The ebuild from my local overlay to install the nVidia CUDA SDK version 3.2.9.
Created attachment 256255 [details, diff] Patch to ebuild to filter out examples that don't compile with gcc-4.5.1
I added a check for GCC 4.4, similar to what was used in SDK 3.0 and older. I would rather not have the ebuild skip compiling some examples depending on the installed GCC version -- the ebuild should always work completely, or not at all, in which case the user should be informed about what to do to mitigate the problem.
