Description (last modified by )
sage: cython? ... For example: #clang C++ #clib givaro #cinclude /usr/local/include/ #cargs -ggdb #cfile foo.c ...
That's misleading, as Cython does only accept #clang c++
but not #clang C++
. Thank you, Burcin, for pointing that out!

I attached a new patch which should allow cython()
to accept #clang C++
as well as #clang c++
. I have no clue how to doctest this.

With your patch, the following still does not work

Hence, one still needs
sage: cython("""#clang c++ #cinclude /home/simon/SAGE/sage-5.0/local/include/singular /home/simon/SAGE/sage-5.0/local/include/factory #clib m readline singular givaro ntl gmpxx gmp from sage.rings.polynomial.multi_polynomial_libsingular cimport MPolynomial_libsingular """)
comment:4 Changed 9 years ago by
My reviewer patch will contain a test such as this:
TESTS: Before :trac:`12975`, it would have beeen needed to write ``#clang c++``, but upper case ``C++`` has resulted in an error:: sage: from sage.all import SAGE_ROOT sage: code = [ ... "#clang C++", ... "#cinclude %s/local/include/singular %s/local/include/factory"%(SAGE_ROOT,SAGE_ROOT), ... "#clib m readline singular givaro ntl gmpxx gmp", ... "from sage.rings.polynomial.multi_polynomial_libsingular cimport MPolynomial_libsingular", ... "from sage.libs.singular.polynomial cimport singular_polynomial_pow", ... "def test(MPolynomial_libsingular p):", ... " singular_polynomial_pow(&p._poly, p._poly, 2, p._parent_ring)"] sage: cython(os.linesep.join(code)) The function ``test`` now manipulates internal C data of polynomials, squaring them:: sage: P.<x,y>=QQ[] sage: test(x) sage: x x^2
But with your current patch, one would still need c++, not C++.

- Description modified (diff)
- Reviewers set to Simon King
I have successfully run the tests in sage/misc with your patch and my reviewer patch. I will wait for a full test run (either by myself or the patchbot) before giving a positive review.
Apply trac_12975-cython_cpp_pragma.patch trac_12975_reviewer.patch
comment:7 Changed 9 years ago by
- Status changed from needs_review to positive_review
make ptest passes, and thus I give it a positive review.
comment:8 Changed 9 years ago by
- Component changed from documentation to interfaces
I changed the component into "interfaces" (to cython), since the fix was not just modifying the documentation, after all.
comment:9 Changed 9 years ago by
- Merged in set to sage-5.1.beta1
- Resolution set to fixed
- Status changed from positive_review to closed
C++ typo fixed.
