[Bug 1785617] [NEW] gcc-multilib not installing libraries
Public bug reported: Something seems wrong with the gcc-multilib. When trying to compile a 32bit app under my 64bit machine the linker complains about not finding -lstdc++. I see that apparently /usr/lib/gcc/i686-linux-gnu/ only contains the gcc-8 stuff, not gcc-7 which is the default. Using Kubuntu 18.04 ** Affects: gcc-defaults (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785617 Title: gcc-multilib not installing libraries To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1785617/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1762652] Re: perf DWARF unwind failed
Well this is more about the user space tool perf, not really the kernel itself. And I can't really imagine why DWARF unwinding would have anything to do with the kernel used. I'm on stock ubuntu 4.13.0-38-generic btw. When I compile perf from the kernel source (commit 2bf1ab321a06a7faeb95c56d02139140fb56199a) it seems that it fails when only having libdw-dwarf-unwind as system feature. When having both libdw-dwarf-unwind and libunwind available the compiled perf does not fail the test. I think that for DWARF unwinding either one of those two libraries should be enough, so maybe this is a bug in libdwarf or how perf uses libdwarf, and when libunwind is available it uses it instead. But just a wild guess, I don't really know what's going on. In any case, a quick "fix" seems to be building perf with libunwind - even if that just masks the actual bug here. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762652 Title: perf DWARF unwind failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1762652/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1750479] Re: 'perf record' does not work
Same problem on 17.10. The packaging seems to be broken; no perf-archive script is installed anywhere. All I can find is /usr/src/linux- headers-4.13.0-38/tools/perf/perf-archive.sh but that is not used -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750479 Title: 'perf record' does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1750479/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
