Hi Michael,
While migrating a project to 2026.02.0 and building from scratch I came
across this build error:
----------------------------------------------
target: host-system-python3-setuptools.compile
----------------------------------------------
[...]
ImportError: Cannot import `packaging.licenses`.
Setuptools>=77.0.0 requires "packaging>=24.2" to work properly.
Please make sure you have a suitable version installed.
So apparently HOST_SYSTEM_PYTHON3_SETUPTOOLS is missing a dependency on
HOST_SYSTEM_PYTHON3_PACKAGING.
But adding this dependency and running oldconfig gets me this:
[..]host-system-python3-flit-core.in:3:error: recursive dependency detected!
[..]host-system-python3-flit-core.in:3: symbol
HOST_SYSTEM_PYTHON3_FLIT_CORE is selected by HOST_SYSTEM_PYTHON3_PACKAGING
[..]host-system-python3-packaging.in:3: symbol
HOST_SYSTEM_PYTHON3_PACKAGING is selected by HOST_SYSTEM_PYTHON3_SETUPTOOLS
[..]rules/host-system-python3-setuptools.in:3: symbol
HOST_SYSTEM_PYTHON3_SETUPTOOLS is selected by HOST_SYSTEM_PYTHON3_FLIT_CORE
And indeed:
$ cat /usr/local/lib/ptxdist-2026.02.0/rules/host-system-python3-packaging.in
## SECTION=hosttools_noprompt
config HOST_SYSTEM_PYTHON3_PACKAGING
tristate
default y if ALLYES
select HOST_SYSTEM_PYTHON3
select HOST_SYSTEM_PYTHON3_FLIT_CORE
$ cat /usr/local/lib/ptxdist-2026.02.0/rules/host-system-python3-flit-core.in
## SECTION=hosttools_noprompt
config HOST_SYSTEM_PYTHON3_FLIT_CORE
tristate
default y if ALLYES
select HOST_SYSTEM_PYTHON3
select HOST_SYSTEM_PYTHON3_SETUPTOOLS
I solved this for my particular situation by removing "select
HOST_SYSTEM_PYTHON3_SETUPTOOLS" from host-system-python3-flit-core.in
I assume this will not work in every situation though. Not sure how to fix
this correctly and it is very possible that I am missing something here.
Best regards,
