I gave it a go today, and I'm not progressing as much as I would like,
because I don't know exactly how such a command-line can come to be:
{{{
python `which cython` --cplus --old-style-globals
--disable-function-redefinition --embed-positions --directive
cdivision=True,autotestdict=False,fast_getattr=True
-I/home/jpuydt/sage-5.0.beta8/devel/sage-main -o
sage/algebras/quatalg/quaternion_algebra_element.cpp
sage/algebras/quatalg/quaternion_algebra_element.pyx
Error compiling Cython file:
------------------------------------------------------------
...
include "ext/cdefs.pxi"
^
------------------------------------------------------------
sage/algebras/quatalg/quaternion_algebra_element.pxd:1:0:
'ext/cdefs.pxi' not found
}}
in module_list.py, there is :
{{{
Extension('sage.algebras.quatalg.quaternion_algebra_element',
sources =
['sage/algebras/quatalg/quaternion_algebra_element.pyx\ '],
language='c++',
libraries = ["csage", "flint", "gmp", "gmpxx", "m",
"stdc++", "n\ tl"],
include_dirs = [ SAGE_INC + 'FLINT/'],
depends =
flint_depends),
}}}
and as you see, there is already an include_dirs list which appears
here... but I don't see any path ending with an uppercase FLINT in the
command line.
I checked that by going in the right directory, and using a
modified command-line with the right -I option, that file compiles.
So I have two questions:
(1) where does the lone -I in the command-line come from?
(2) how come the include_dirs isn't used at all!? Isn't that supposed
to be precisely its intent?!
