issues testing from octave

[fabianp]

Hi,

I'm running orca from Octave installed from ubuntu 18.10.

Installation goes fine but when I try to run the tests (from Octave shell) I get the following errors.

warning: struct: converting a classdef object into a struct overrides the access restrictions defined for properties. All properties are returned, including private and protected ones.
warning: called from

any clue on what is causing the error?

Hi Fabian,

Thanks for your comment. Could you please specificy what version of Octave are you using? We have some issues with recent versions...

Best regards,

Pedro

Hi Pedro,

I'm using version 4.2.2, which is the one that comes bundled with Ubuntu 18.10 LTS

Thanks. I've reproduced the errors in a clean installation of Ubuntu (we used Linux Mint 18.3 previously so we didn't got the error).

I have fixed some issues regarding compilation with newer versions. I suspect that there is some problem with some shared env variables since the tests are ok when run individually. I'll work on that during the weekend.

thanks!

After examining the issues. The tests (single and cv) works if we do 'clear all' before each test. I've examined path, variables and environment and I can't find the problem in Octave 4.2.2 (it worked previously in 4.2). We are properly cleaning the path after every fit/predict call that needs C code.

My temporal solution proposal is to rewrite the tests to add a 'clear all' at the very beginning and keep the issue open. This does not sound weird at all in Matlab/Octave since many scripts start with 'clear all'.

Hi @fabianp,

This issues should be now fixed in Octave +4.2.2 in Ubuntu. Also, I test the changes in Matlab 2017b (Windows and Linux). Please, let us now if this works for you. I'll merge to master now.

Master branch passes tests for Octave 4.2 (official PPA) and Octave 4.4 (Ubuntu 18.10).

Octave 4.2 is in travis CI now, so we should be able of detecting these type of problems in the future.

Thanks.

Tests are ok in travis https://travis-ci.org/ayrna/orca
