 |
|
As of yesterday 'emerge --depclean -p' states that it wants to remove sys-devel/lld:
| Code: | >>> These are the packages that would be unmerged:
app-doc/python-docs
selected: 3.12.6
protected: none
omitted: 3.13.0
sys-devel/lld-toolchain-symlinks
selected: 18
protected: none
omitted: none
sys-devel/lld
selected: 18.1.8
protected: none
omitted: none |
However it appears that my system still needs sys-devel/lld ...
| Code: | $ equery depends sys-devel/lld
* These packages depend on sys-devel/lld:
app-emulation/wine-vanilla-9.0 (sys-devel/lld)
app-office/libreoffice-24.2.6.2 (clang ? =sys-devel/lld-18*)
(=sys-devel/lld-17*)
(=sys-devel/lld-16*)
(=sys-devel/lld-15*)
dev-lang/rust-1.81.0 (wasm ? sys-devel/lld:18)
...
mail-client/thunderbird-128.4.0 (clang ? sys-devel/lld:17)
(clang ? sys-devel/lld:18)
(clang ? sys-devel/lld:19)
sys-apps/pciutils-3.13.0 (sys-devel/lld)
sys-devel/clang-18.1.8 (test ? ~sys-devel/lld-18.1.8)
sys-devel/clang-common-18.1.8-r3 (default-lld ? >=sys-devel/lld-18.1.8)
sys-devel/lld-toolchain-symlinks-18 (sys-devel/lld:18)
www-client/firefox-128.4.0 (clang ? sys-devel/lld:17)
(clang ? sys-devel/lld:18)
(clang ? sys-devel/lld:19) |
Why does 'emerge --depclean' want to remove sys-devel/lld?

| emerge --depclean wants to remove lld because nothing in @world needs (even recursively) lld to be installed. As we have been telling people a lot lately, don't trust equery, because it does not resolve conditional dependencies. It shows that you could need lld with the right USE flags or the right other conditional relations satisfied. |

equery depends is inaccurate and returns inaccurate information.
| Code: |
# wine-vanilla
BDEPEND="
|| (
sys-devel/binutils
sys-devel/lld
)
|
| Code: |
# libreoffice
BDEPEND="
clang? (
|| (
( sys-devel/clang:18
sys-devel/llvm:18
=sys-devel/lld-18* )
( sys-devel/clang:17
sys-devel/llvm:17
=sys-devel/lld-17* )
( sys-devel/clang:16
sys-devel/llvm:16
=sys-devel/lld-16* )
( sys-devel/clang:15
sys-devel/llvm:15
=sys-devel/lld-15* )
)
|
| Code: |
# thunderbird
BDEPEND="${PYTHON_DEPS}
$(llvm_gen_dep '
sys-devel/clang:${LLVM_SLOT}
sys-devel/llvm:${LLVM_SLOT}
clang? (
sys-devel/lld:${LLVM_SLOT}
virtual/rust:0/llvm-${LLVM_SLOT}
pgo? ( sys-libs/compiler-rt-sanitizers:${LLVM_SLOT}[profile] )
)
')
|
| Code: |
# pciutils
# See bug #847133 re binutils check
BDEPEND="
|| ( >=sys-devel/binutils-2.37:* sys-devel/lld sys-devel/native-cctools )

As you can see, in all these cases lld is not required as it is either conditional on USE flag, exists in an "any-of" group, or both.
I haven't checked all your examples -- all I did was check and explain a sample of them -- but I am sure you will find the rest have the same pattern.
emerge --depclean removes packages if it is possible to do so, it is possible in these cases, so there you have it. But in some cases if you had built with USE=clang it might have kept lld.  |

Thank you.
I let 'emerge --depclean' remove sys-devel/lld and those listed apps in my original post still work without issue. |
