Re: [gentoo-user] OT: latest longterm kernel.org patches are unsigned
Hi, kernel.org won’t provide the signatures anymore. I was politely pointed to the following site via IRC but got no reason for it. https://www.kernel.org/category/site-news.html --- Quote --- No future PGP signatures on patches and changelogs For legacy purposes, we will continue to provide pre-generated changelogs and patches (both to the previous mainline and incremental patches to previous stable). However, from now on they will be generated by automated processes and will no longer carry detached PGP signatures. If you require cryptographically verified patches, please generate them directly from the stable git repository after verifying the PGP signatures on the tags using git verify-tag. --- EOQ --- Am Freitag, 17.

[gentoo-user] Valgrind not seeing debug symbols
Hi all, I have this project https://github.com/Tatsh/gcrud and it uses a very standard build process with CMake, but for some reason Valgrind never sees the debug symbols. The debug symbols are definitely there as GDB can see them, but I have not been able to figure out why Valgrind can't. I have the latest version of Valgrind which supports compressed debug symbols. I even created an ebuild to see if Portage does the magic I need: https://github.com/Tatsh/tatsh-overlay/blob/master/app-portage/gcrud/gcrud-.ebuild Portage does not generate the debug symbols file I expect to see. In all cases I am building with -ggdb. I have FEATURES="splitdebug compressdebug" and still no debug symbols: $ valgrind -v --leak-check=full gcrud ... ==16662== 1,120,873 bytes in 16,784 blocks are definitely lost in loss record 41 of 41 ==16662==at 0x4C30D6F: realloc (vg_replace_malloc.c:785) ==16662==by 0x5266BA5: __vasprintf_chk (vasprintf_chk.c:88) ==16662==by 0x4ECA438: vasprintf (stdio2.h:210) ==16662==by 0x4ECA438: g_vasprintf (gprintf.c:316) ==16662==by 0x4EA482C: g_strdup_vprintf (gstrfuncs.c:514) ==16662==by 0x4EA48F0: g_strdup_printf (gstrfuncs.c:540) ==16662==by 0x10AB1A: ???

I think you have to not have multiple LLVM/Clang installations, unfortunately. That's what the bug indicates.

Have you tried disabling the llvm USE flag of mesa? AFAIK it's only used for the software rendering backend, which you probably don't need. Try disabling it, and then do: emerge -auDN --changed-deps --with-bdeps=y @world followed by: emerge -a --depclean which should unmerge llvm:5.

Hi there, After recent upgrades of mesa, llvm, clang etc kdevelop does not work anymore. It crashes immediately after start with errors : CommandLine Error: Option 'help-list' registered more than once!

It seems as if multiple slots of llvm cause the problems. mesa pulls in llvm: 5, while other programs pull in llvm:6 (via clang:6) Does anyone have an idea how to get a working kdevelop again?

You can switch if off by disabling CONFIG_DEBUG_STACK_USAGE in the kernel. Some ebuilds, I have chromium in mind here, can chew up all your RAM and then start thrashing swap continuously. To make matters worse in pre-empting this, they only do it for a few versions, then revert to better managed memory usage. On a box with 4G RAM I set MAKEOPTS="-j2 -l2" for such troublesome packages and swap usage is kept within normal limits.

Re: [gentoo-user] python-3.6.5 rebuild fails on new install
I think the memory is only used in the context of OpenGL (or when it's used for computing like with OpenCL). I am sure you won't run out of memory when compiling on a pure text console because of the grahics driver. Am So., 19.
