Comment 2 Sam James archtester gentoo-dev Security 2020-08-25 00:24:35 UTC
I really need you to try again with vanilla CFLAGS/LDFLAGS, because the emerge --info for Blender claims it wasn't built with those:

>CFLAGS="-march=skylake -mtune=skylake -O2 -pipe -ftree-loop-vectorize -funsigned-char"
>CXXFLAGS="-march=skylake -mtune=skylake -O2 -pipe -ftree-loop-vectorize -funsigned-char"
>LDFLAGS="-Wl,-O1 -Wl,-fuse-ld=bfd -Wl,--enable-new-dtags -Wl,-z,relro -Wl,-z,now -fno-plt -march=skylake -mtune=skylake -O2 -pipe -ftree-loop-vectorize"

Also, a gdb backtrace would be enormously helpful.

openvdb [with no nvidia] & osl are segfault showstopper here.
Didn't test man ndof nls opencl sdl valgrind, not expecting major issue but from opencl possibly due to environment integration.

Thks 4 ur attention, interest & support.
Comment 5 Adrian 2020-08-28 19:26:30 UTC
I am not able to replicate this here.

I have tried enabling the use flags in your report: USE="alembic bullet collada color-management cycles dds elbeem ffmpeg fftw jack jemalloc jpeg2k llvm openexr openimageio openmp opensubdiv sndfile standalone system-numpy system-python tbb tiff -abi6-compat -abi7-compat -cuda -debug -doc -headless -man -ndof -nls -openal -opencl -openvdb -osl -sdl -test -valgrind" ABI_X86="(64)" PYTHON_SINGLE_TARGET="python3_7" and blender compiles and runs. From what I understand, you were able to build this version and it works for you.

I have also tried enabling openvdb and osl but not cuda giving USE="abi7-compat alembic bullet collada color-management cycles dds elbeem ffmpeg fftw jack jemalloc jpeg2k llvm openexr openimageio openmp opensubdiv openvdb osl sndfile standalone system-numpy system-python tbb tiff -abi6-compat -cuda -debug -doc -headless -man -ndof -nls -openal -opencl -sdl -test -valgrind" ABI_X86="(64)" PYTHON_SINGLE_TARGET="python3_7" and blender compiles and runs. I provide my emerge --info blender for comparison.

I am able to open blender and render the default cube with both eevee and cycles.

As Sam mentioned, a backtrace would be useful.

Created attachment 657338 [details]
Working blender USE flags on my system
Comment 7 CaptainBlood 2020-08-29 00:21:33 UTC
Trying my best...
By no nvidia I meant USE=-cuda along with no Nvidia hardware aboard nor configured at OS level.
Plz note both clang:9 & clang:10 installed here, as far as USE=osl is concerned.
In this respect, I'll try to force :9 via /etc/portage/package.env.

But first, currently testing openvdb with:
dev-libs/c-blosc
Installed versions:  1.19.0(0/1)^t(03:11:52 29/08/2020)(-lz4 -snappy -test -zlib -zstd)

dev-libs/log4cplus
Installed versions:  1.2.0(0/1.2-5)(03:11:39 29/08/2020)(-iconv -qt5 -threads -working-c-locale -working-locale).

Will strace segfault cases.

I still really need you to rebuild this with vanilla CFLAGS, CXXFLAGS, and LDFLAGS.
Comment 9 CaptainBlood 2020-08-29 01:21:53 UTC
Truly confused about openvdb as it seems to have been build here only once & that is now!!!

Beside that, blender runs fine here with
Installed versions:  2.83.4^t(03:52:13 29/08/2020)(abi7-compat alembic bullet collada color-management cycles dds elbeem ffmpeg fftw jack jemalloc jpeg2k llvm openexr openimageio openmp opensubdiv openvdb sndfile standalone system-numpy system-python tbb tiff -abi6-compat -cuda -debug -doc -headless -man -ndof -nls -openal -opencl -osl -sdl -test -valgrind PYTHON_SINGLE_TARGET="python3_7")

emerge --info:
CFLAGS="-march=skylake -mtune=skylake -O2 -pipe"
CXXFLAGS="-march=skylake -mtune=skylake -O2 -pipe"
LDFLAGS="-Wl,-O1 -Wl,-fuse-ld=bfd -march=skylake -mtune=skylake -O2 -pipe"

emerge --info blender:
media-gfx/blender-2.83.4::gentoo was built with the following:
USE="-abi6-compat abi7-compat alembic bullet collada color-management -cuda cycles dds -debug -doc elbeem ffmpeg fftw -headless jack jemalloc jpeg2k llvm -man -ndof -nls -openal -opencl openexr openimageio openmp opensubdiv openvdb -osl -sdl sndfile standalone system-numpy system-python tbb -test tiff -valgrind" ABI_X86="(64)" PYTHON_SINGLE_TARGET="python3_7"

CXXFLAGS="-march=skylake -mtune=skylake -O2 -pipe -ftree-loop-vectorize -funsigned-char"
FEATURES="pid-sandbox sandbox binpkg-logs news preserve-libs merge-sync sfperms config-protect-if-modified usersync distlocks assume-digests qa-unresolved-soname-deps multilib-strict fixlafiles ebuild-locks strict unmerge-logs binpkg-dostrip protect-owned network-sandbox unknown-features-warn binpkg-docompress unmerge-orphans userpriv ipc-sandbox usersandbox userfetch parallel-fetch split-elog"
LDFLAGS="-Wl,-O1 -Wl,-fuse-ld=bfd -march=skylake -mtune=skylake -O2 -pipe -ftree-loop-vectorize"

So I guess your request for vanilla would be to remove CPU & link optimisation, since it appears all -fxyz are coming from blender itself.

Again, I'm truly sorry for what seems a stupid mistake on my part.

The remaining bit, e.g. osl has been definively built here, let's see if I can fix something about it, forcing clang:9 as I suspect package to call for unversioned clang.
