lagrange-ng's Issues

Building error

Dear authors,

Machine: Ubuntu 20.04.4

Hello! I'm currently having some difficulties building Lagrange-ng on my terminal. After git clone the repo, I issued the make command and the building started. However, I tried several times and it always stopped early and gave this error:
image

The debug file is attached here:
lagrange_error_debug.log

Could you please have a quick look into this issue? Any response will be much appreciated. Cheers!

Best regards,
Robert

Breaking typo in tests + dereferencing null pointer error.

Hi, and thank you for this rewriting of Lagrange :)

I have downloaded the project, but the tests do not pass on my machine:

  • The first failure seems to be a simple mistake that the lagrange_mode::OPTIMIZE identifier had not been correctly renamed to lagrange_operation_mode::OPTIMIZE within tests/src/context.cpp.
  • But the second failure seems more engaged, as it involves null pointer dereferencing:

Is this an easy fix? Do the tests pass on your machines? If yes, would it be an architecture-related problem?
