Build fails: error: no matching function for call to '__sort' about pysph HOT 13 CLOSED

Hi @yurivict -- Thanks for the instructions. I've managed to setup a VM with FreeBSD.
I've fixed one of the issues in pypr/cyarray#1
I am able to reproduce your error and see a few more things I can fix. I hope I should be able to fix it soon. BTW, I think the package will build fine with gcc but I would like to make sure that it works with clang also.

This looks like a C++ compiler setup issue from the look of it. I build on OS X with their clang (and also with gcc) but haven't tried on another system with clang.

@prabhuramachandran I have clang-6.0.1. What clang did you try on OS X?
clang-7.0.0 fails the same way.

from pysph.

It builds if in this file/place to remove the comparator element from the std::sort template parameters.

@yurivict -- I have this, which seems a bit meaningless Apple LLVM version 10.0.0 (clang-1000.10.44.4) .
Do the tests pass with your modifications? The additional comparator is needed for one of the calls. Perhaps there is a better way of doing this? I will need to investigate this more closely and will do so when I get some time later this week.

@yurivict -- would you be willing to help with this? I am unable to reproduce the error so am not sure how best to proceed. Could you please send me the full error message? Thanks.

Now it breaks with this message:

pyzoltan/core/carray.cpp:44253:3: error: cannot initialize return object of type 'int' with an rvalue of type 'nullptr_t'
  import_array();
  ^~~~~~~~~~~~~~

This file appears to be C++ generated from python.

carray is now in its own package called cyarray from pypi or here https://github.com/pypr/cyarray. import_array ought to work as it is used all over the place for numpy, again, if you share the full log -- you can directly email me if you don't want to attach it here.

I am thinking of trying freebsd on a virtual machine, so if you can tell me the steps you followed to perform the installation on a fresh system, that would help.

from pysph.

1. Download this ISO image: https://download.freebsd.org/ftp/releases/amd64/amd64/ISO-IMAGES/12.0/FreeBSD-12.0-RELEASE-amd64-disc1.iso
2. Create a VirtualBox VM with it.
3. While installing it in VM, choose to install the ports collection
4. Boot this VM up
5. Download this shar: https://people.freebsd.org/~yuri/py-PySPH.shar
6. Unpack it while in /usr/ports
7. Go into the port: /usr/ports/science/py-PySPH
8. Type 'make'

It will begin to build the port, and fail with the error above.

from pysph.

You can also execute 'pkg install python36' to install it from binary, and prevent its rebuild.

from pysph.

Thanks for fixing the issues. We mostly use clang on FreeBSD.
I will try to create a port again, once you are done.

Hi @yurivict -- I've fixed the issues in pysph and compyle. If you use master of cyarray, compyle and pysph it should work on freebsd with clang. It should also work fine with openmp. Please let us know if you run into any other issues.
