Hi folks

Can anybody help me to understand what's going on here? I did a regular `emerge --blahblah @world`, and I get the attached message about boost.

It seems to me that emerge wants to install version 1.85.0-r1, but can't because other things depend on 1.84.0 (?) I looked in the .ebuild files for the packages that it's complaining about, and none seem to express a need for some specific version of boost -- not that I can see, anyway.

Can anyone explain why the upgrade can't be done? Or (better) how I can find out myself? And does it matter?

BR, Lars

This is a featwre of a rolling release distro.

There is a newer version of boost in the tree than the version you have installed.
However, you can't have it yet as other things that depend on boost, need the older, installed version.

Once everything is updated to use the new boost, it will install.

Thanks.

For my own education, it would be nice if I had a way to figure out what was holding boost at the older version. The .ebuild files for the conflicts don't seem to provide the answer. Not that I can understand, anyway.

BR, Lars.

Seems like the current packages you have installed needs a mix of python 3_11 and 3_12 to be satisfied, ie. libreoffice-bin is 3_11 - so might need python3_11 enabled for boost, too?

lars_the_bear,

Code:
   dev-libs/boost:0/1.84.0= required by ...
is the clue here.
The PYTHON version is a red herring in this case

Thanks. But I looked at the packages that were said to be required, and they didn't seem to have an ebuild dependency on a specific version of Boost. For example,
Code:
freecad-0.21.2-r3.ebuild
has:

Code:

RDEPEND="
        ${PYTHON_DEPS}
        dev-libs/OpenNI2[opengl(+)]
        dev-libs/boost:=
        dev-libs/libfmt:=
        ...


Unless I'm missing something (and that wouldn't be unusual), I don't see anything that asks for a specific Boost version. What have I overlooked this time?

BR, Lars.

:=Means any slot is acceptable. Additionally indicates that your package should be rebuilt if the version best matching the runtime dependency is updated to a version with a different slot or subslot. (cf wiki)

The binary LibreOffice seemingly does, in the form of a subslot:

libreoffice-bin-7.6.7.2.ebuild
Code:
BIN_COMMON_DEPEND="
   ...
   dev-libs/boost:0/1.84.0
   ...
"

Ah, OK. That makes sense. Thanks.
