I installed this package with USE="debugger doc profiler -eclipse" and I have nvvp and nvprof in /opt/cuda/bin. But there are two mistakes: 1. /opt/cuda/libnvvp/nvvp does not have executable attribute. 2. /opt/cuda/bin/nvprof is a wrapper that exec itself. Running this would spawn unlimited number of processes until system resource (in this case, argument length reached limit first) is depleted and fail. Problem 1 is easily fixed with chmod +x Problem 2 is caused (inside ebuild file) by use profiler && \ make_wrapper nvprof "${ecudadir}/bin/nvprof.bin" "." ${ecudadir}/lib64:${ecudadir}/lib" The generated wrapper "nvvp" overrides the binary "nvvp" provided by nvidia. Maybe we could rename the binary nvvp to nvvp.bin before generating the wrapper.
Just realized that some other binaries in the following folders are also missing the +x permission: /opt/cuda/NsightCompute-2019.1 /opt/cuda/NsightCompute-2019.1/host/linux-desktop-glibc_2_11_3-x64 /opt/cuda/NsightCompute-2019.1/target/linux-desktop-glibc_2_11_3-x64 I haven't done a full test but looks like /opt/cuda/NsightSystems-2018.3 also suffer from the same problem. Some other files, though not needing +x permission, however, are with +x, e.g. EULA.txt, and some pdf docs.
This problem persist in 10.1.168
I have this same problem, and I can confirm the fix.
Created attachment 597600 [details, diff] A patch that fixes the problem with nvprof The Nsight problem and nvvp problems seem to have gone away in newer versions of the ebuild.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=750c970f8e3441f1379b862479c55636d731f3ec commit 750c970f8e3441f1379b862479c55636d731f3ec Author: Robert Underwood <rr.underwood94@gmail.com> AuthorDate: 2019-12-14 22:20:13 +0000 Commit: Jason Zaman <perfinion@gentoo.org> CommitDate: 2020-02-16 13:34:15 +0000 dev-util/nvidia-cuda-toolkit: nvprof/nsight fix Previously, there were bugs in the ebuilds that prevented nsight and nvprof from being installed correctly. For nvprof, a no longer needed wrapper was begin installed on top of it. In the case of nsight, it was not setting the executable to a+x. Additionally, cuda-config was being installed in a way would cause ebuild to complain about permissions. These were resolved with better use of doexe. Additionally, fixed revdep-rebuild warnings with cuda profiling libraries.
