Re: [sage-devel] Re: What is the right way to deal with mpfr_t arrays/vectors/lists in cython?

Anyway, you should also return the size of the allocated block. It might be more standard to use slong my_function(mpfr_ptr * answer, mpfr_ptr coeffs, slong length) where the output would be the size of the allocated block at "*answer". Don't you have a reasonable bound on the size of the

Hi Thanks. I've just uploaded 7.5.1 to https://launchpad.net/~aims/+ archive/ubuntu/sagemath-dev/+packages Note it is the sagemath-dev repo not the sagemath repo. Would you be willing to test it? Regards, Jan On 4 February 2017 at 21:07, Antonio Valdés Morales wrote: > Dear

Thanks for the hint. Compiling in plain python complained about some missing header files. Adding them to the include path seemed to solve the problem for now. El domingo, 5 de febrero de 2017, 13:25:48 (UTC+1), Volker Braun escribió: > > On Sunday, February 5, 2017 at 11:38:25 AM UTC+1,

Re: [sage-devel] Re: What is the right way to deal with mpfr_t arrays/vectors/lists in cython?

I see. One problem here is that I don't know in advance the size of the returned list, so the allocation should happen in the c++ library side. So I am guessing the way around it is to return a pointer to the mpfr_ptr. Right? El domingo, 5 de febrero de 2017, 11:43:54 (UTC+1), vdelecroix

[sage-devel] Conda package for Sage

I've packaged sage 7.5.1 for conda for linux and have uploaded it to anaconda.org. To try it out you can do on linux with miniconda3, (Downloads about 1 GB) conda create -n sage sage sage-spkg-sources -c isuruf -c conda-forge This was a hacky build and I don't expect everything to work

Re: [sage-devel] Re: What is the right way to deal with mpfr_t arrays/vectors/lists in cython?

If you want to be complient with GMP/MPFR/FLINT you should change the signature of mpfr_t* my_function (mpfr_t *_coef) to void my_function(mfpr_ptr result, mpfr_ptr input, slong len) And such function should not do any allocation at all. Le 05/02/2017 à 11:40, Vincent Delecroix a

Re: [sage-devel] Re: What is the right way to deal with mpfr_t arrays/vectors/lists in cython?

If you had a look at the code I provided you can check that what you did is very wrong. mpfr_t is already an array. The type "mpfr_t * x" make no sense at all. Le 05/02/2017 à 11:38, mmarco a écrit : I am afraid I didn't explain my problem well enough. My problem is not to write c++ code

I am afraid I didn't explain my problem well enough. My problem is not to write c++ code with mpfr. That is solved It is also not to call c++ libraries from cython code that involves plain mpfr numbers. That is also solved. My problem is to do so with functions that involve *arrays *(or lists,

Re: [sage-devel] What is the right way to deal with mpfr_t arrays/vectors/lists in cython?

Hi Vincent, aren't these two things solving different problems? (the first is doing MPFR in C++, the second - MPFR in Cython) As a C++-phobic person, I'd resort to interfacing via a plain C function. https://isocpp.org/wiki/faq/mixing-c-and-cpp I.e. I would do a plain C extension utilizing the
