 Posted: Fri May 09, 2025 10:49 pm Post subject: media-gfx/openvdb USE=ax stable masked, keyworded removed? |
 |
|
USE=ax has been removed from long standing stable 11.0.0-r1 and new 12.0.1.
Ebuild reveals USE=ax still remains for 9999.
I don't understand the rationale for such a change?
Is the feature broken?

| As I read the ebuild, USE=ax is still supported in =media-gfx/openvdb-11.0.0-r1. Why do you think it was removed? I also see in the git history that this was USE-masked for media-gfx/openvdb[ax]: requires LLVM 15. |

| Code: | euse openvdb-11.0.0-r1
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-gfx/openvdb-11.0.0-r1:
U I
- - abi10-compat : Disables newer features to maintain
compatibility with ABI10
+ - abi11-compat : Disables newer features to maintain
compatibility with ABI11
- - abi12-compat : Disables newer features to maintain
compatibility with ABI12
- - abi9-compat : Disables newer features to maintain
compatibility with ABI9
- - alembic : Add support for Alembic through
media-gfx/alembic.
+ - blosc : Allow using blosc compression via
dev-libs/c-blosc
+ + cpu_flags_x86_avx : Adds support for Advanced Vector
Extensions instructions
+ + cpu_flags_x86_sse4_2 : Enable SSE4.2 instruction support
- - doc : Add extra documentation (API, Javadoc,
etc). It is recommended to enable per
package instead of globally
- - examples : Install examples, usually source code
- - jpeg : Add JPEG image support
+ - llvm_slot_15 : Use LLVM 15.
- - nanovdb : A lightweight, header only, and GPU
friendly version of VDB
- - numpy : Build pyopenvdb with support for
dev-python/numpy
- - openexr : Support for the OpenEXR graphics file
format
- - png : Add support for libpng (PNG images)
- - python : Add optional support/bindings for the
Python language
- + python_single_target_python3_11 : Build for Python 3.11 only
- - python_single_target_python3_12 : Build for Python 3.12 only
- - static-libs : Build static versions of dynamic
libraries as well
- - test : Enable dependencies and/or preparations
necessary to run tests (usually
controlled by FEATURES=test but can be
toggled independently)
- - utils : Build utility binaries
+ - zlib : Add support for zlib compression
|
What makes you think it is still there?
LLVM 15 ... Sio what?

As I said, as I read the ebuild, it is still there: | Code: | $ git grep -e 'IUSE.*ax' 03952664c16a334a1006d52d43d7682ddbcc146d -- media-gfx/openvdb/\*.ebuild

Yes. From upstream :

| Code: | grep -E -r 'openvdb.*ax' /var/db/repos/gentoo/profiles
/var/db/repos/gentoo/profiles/use.local.desc:media-gfx/openvdb:ax - Build the OpenVDB AX module to perform custom manipulation of OpenVDB data via an expression language: AX
/var/db/repos/gentoo/profiles/base/package.use.mask:media-gfx/openvdb ax |
At first sight seems 2 me like USE=ax is masked for any openvdb ebuild, i.e. requiring | Code: | | /etc/portage/profile/package.use.mask/media-gfx::openvdb.conf:=media-gfx/openvd -11.0.0-r1 -ax |
for activation.
Before r1 bump here without any USE mask as above: | Code: | gunzip -c /var/log/portage/media-gfx:openvdb-11.0.0:20240731-004601.log.gz|grep -E 'USE.* ax'
* USE: abi11-compat abi_x86_64 amd64 ax blosc cpu_flags_x86_avx cpu_flags_x86_sse4_2 elibc_glibc kernel_linux zlib |
Plz note above unmasking doesn't work when above is adapted for 12.0.1, because of ebuild internal changes, i.e. ax is only available for an hypothetical 9999 that currently doesn't exist.

Things got masked because existing stable llvm-core/llvm:15. 
llvm-core/llvm:15 removal may be on its way  
Maybe it's time to backup clang;15 & llvm:15 ebuild stack to local repository before things get harder.

Yes, the flag is masked in the 11.x series, but it is not removed. Your original statement was: | CaptainBlood wrote: | | USE=ax has been removed from long standing stable 11.0.0-r1 and ... |
I pointed out that it is not removed from that ebuild, merely difficult to enable due to the use.mask entry. |

Indeed. Sometimes the infra for these things is kept around for a while in hopes of upstream progress, at which point it'll be enabled again. I'm not really sure what's surprising here. LLVM 15 already required several backports to keep building and we can't do that forever.
OP, are you actually using the ax functionality? Or what? |
