Issues compiling files

[LittleHalfling]

Hi!
I'm trying to follow the instructions in the READ.ME file for the project and am working on getting the test file 'test_continuous_to_continuous.py' to run, as the steps suggest running test files from helit/frf. I am currently encountering the following error when trying to run setup.py to create frf_c.so:
veronica@veronica-virtual-machine:~/helit/frf$ sudo python2 setup.py install
[sudo] password for veronica:

There is a workaround to now inherit optimization CFLAGS when compiling wheels.
To enable this, set APPLY_LP2002043_UBUNTU_CFLAGS_WORKAROUND in your

Do other header/source files in different directories need to be compiled to resolve this issue? What can I do to run the program?

[LittleHalfling]

@thaines Would you be able to help troubleshoot the setup process? In this particular instance, the test file is not running due to a multiple symbol definitions error.

[thaines]

Sorry for the slow reply, though this code is very old now, and effectively here for reference, nothing more. I actually haven't a clue how to fix this problem: it's clearly some kind of code rot, where the libraries used have changed and that's causing the symbol clash, presumably because I'm doing something in a way that is now depreciated or was never meant to work in the first place. I'm afraid that this is unlikely to compile within a modern environment as Python 2 is now end of life, scipy.weave is effectively dead, and many of the libraries have moved on, to the point of being very different indeed. If I wanted to get this running now I'ld be looking into finding a virtual machine running something like Ubuntu 16.04 and doing so within that. To actually fix it to run on a modern computer, while doable, is going to be at least a weeks worth of incredibly fiddly fixes (including conversion to Python3), probably a months, and that's assuming I do it and can remember this code well enough for that to help (a big assumption).

[LittleHalfling]

@thaines That would make sense. I was successful at running the test files in Ubuntu 15, as I was originally running off the latest version of it. This is a good sign. However, I am now facing the issue of being unable to pip install weave in order to run main.py in /let due to weave being deprecated. I know rewriting this code for Python 3 would take an immense amount of work, but is there any way to install weave in Python 2.7?

[LittleHalfling]

@thaines Okay, so after a LOT of tinkering in Ubuntu 15's terminal and downloading a version of scipy-weave that could run weave, I managed to get the program to open. If you're able to recall how your program is used, the only issue I'm facing at this point is I don't seem to be tagging the text correctly, as I'm unable to generate any more than 1 letter at a time. If you have any tips on getting hst to generate full words, I'd appreciate it. Thanks for giving me the idea to try an older version of Ubuntu!
