[Marc Culler]

I was able to build 10.9beta7 with gcc 10 in a linux docker image, after removing the new gmp patch for gcc15 compaiibility, which also seems to break gcc 10 compatibility.

However, the documentation build fails on the [knots ] package (and on other packages - that is just the first one).  A traceback for that first failure is pasted from the log below,. (I am not allowed to attach files.) 

I think the relevant part is at the end:

[spkg-install] [knots    ]   File "/var/tmp/sage-10.9/local/lib/python3.14/site-packages/sage/groups/free_group.py", line 741, in __init__
[spkg-install] [knots    ]     gap_group = libgap.FreeGroup(generator_names)
[spkg-install] [knots    ]   File "sage/libs/gap/element.pyx", line 2698, in sage.libs.gap.element.GapElement_Function.__call__
[spkg-install] [knots    ]     GAP_Enter()
[spkg-install] [knots    ] sage.libs.gap.util.GAPError: Error, FreeGroup: function is not yet defined [docutils]

There are similar failures in other plots.  For example:

sage.categories.finite_coxeter_groups.FiniteCoxeterGroups.ParentMethods.permutahedron:50: WARNING: Exception occurred in plotting finite_coxeter_groups-1

I think all of the exceptions I am seeing involve missing GAP functions.  For another example, with a missing method:

[spkg-install] [categorie]   File "sage/libs/gap/element.pyx", line 2698, in sage.libs.gap.element.GapElement_Function.__call__
[spkg-install] [categorie]     GAP_Enter()
[spkg-install] [categorie] sage.libs.gap.util.GAPError: Error, no method found! Error, no 1st choice method found for `RealPart' on 1 arguments [docutils]

[Dima Pasechnik]

Why does one need to use an obsolete compiler? Gcc project only supports gcc 13+ nowadays.
We don't test with gcc 10.
