Comment (by pcpa):
The attached patches allow continuing experimenting with a new sagemath
rpm.
The patches are only tested to know they make sagemath and linbox agree on
api/abi, but no testing done.
There were missing prototypes/templates in linbox-sage.h as well as wrong
ones.
I am not fully confident that some place may do wrong dereferencing of
matrix fields due to upstream change from a vector of rows where every row
is an allocated pointer to a single memory chunk.
Another part I am not confident is that I did the correct logic in the
change from
A_nr, A_nc, B_nr, B_nc to test in sage code `if A_nr != B_nc: ...`, and
convert the values of `m, n, k` as
`A_nr, A_nc, B_nr`.
This is not a proposal of a final patch, but a extra call for more
feedback. As this was also the first time I actually did look at linbox
code, so, just patched the interfaces to make both sides agree.
