Hello,
I had a closer look and the problem seems to originate mostly in the
coercion code:
I changed all single letter capital variables in
sage/structure/coerce.pyx
sage/structure/element.pyx
sage/categories/action.pyx
sage/structure/parent.pyx
but I still get a compilation failure in coerce.c (and others). If you
look at coerce.c lines 824, 825 you will see the PyObject _G and _S:
struct __pyx_obj_4sage_10categories_6action_Action {
struct __pyx_obj_4sage_10categories_7functor_Functor __pyx_base;
struct __pyx_vtabstruct_4sage_10categories_6action_Action
*__pyx_vtab;
PyObject *_G;
PyObject *_S;
int _is_left;
PyObject *_op;
};
I did make all the changes needed in action.pyx, so can somebody
please tell me where G and S are defined in this context. I can edit
the c-files and make it compile, but that is obviously not the long
term solution. If I am not mistaken the coercision code was written by
Robert Bradshaw, so Robert do you have any idea?
I did edit all the needed bits to make the coerce code compile, but
now I get the following failure in multi_polynomial_libsingular:

sage: There was an error installing modified sage library code.
malb, any idea? I don't know that area of the code very well. It looks
like a missing include.
Cheers,
Michael
