Source: ensmallen Followup-For: Bug #1054712 Control: forwarded 1054712 https://github.com/mlpack/ensmallen/issues/372
This error occurs because of the upgrade of catch2 from v2 to v3. Unfortunately ensmallen upstream don't sound very enthusiastic about dealing with it, https://github.com/mlpack/ensmallen/issues/372 Arguably the catch developers made life unjustifiablydifficult. Maybe they should have released catch3 rather than catch2 v3. On the other hand, judging by the patch for termpaint, the required changes are likely to be essentially trivial, e.g. #include "catch2/catch_all.hpp" instead of #include "catch2/catch.hpp" cf. https://github.com/termpaint/termpaint/commit/dc293554b745b3f010445e9445e620399f8ee2f7
