Since you don't have an issue tracker, I can only put this here...
Assertion failure at DestroyableInactive (serious-engine-git/src/Serious-Engine/Sources/EntitiesMP/EnemySpawner.es:419), triggered 1 time: '0'
From this thread where someone was requesting a PKGBUILD to install the Serious Engine on Arch-Linux. Here's the PKGBUILD in question, which builds/installs fine as far as I'm aware.

I'm not familiar with the PKGBUILD process, but:

  1. be sure to use separate build tree for TSE and TFE, as there are some common file compiled, but with different define.
  2. be sure to build a Release build, not a Debug one, as the debug build assert a lot.
  3. I don't think SeriousEngine is 64bits clean yet. In any case, be sure to not use ASM when building on 64bits. If possible, prefer 32bits build. I haven't tested much 64bits build. It start IIRC, but not sure it's playable.

(Shall I activate issue tracker on github?).

I'm running rm -rf cmake-build between TSE and TFE builds, I assumed that would be enough?

Thanks, will switch to Release.

I'm just using the AMD64 line on the cmake (the one not commented out). Is that incorrect?

The cleaning looks fine yes.

About 64bits, I know it build fine on 64bits. The point is, I'm not sure it does run on 64bits (last time I tried, it didn't, but it was at the beginning of the OpenSource Linux port, so it may be better).
Let's say 64bits is for advanced user and may crash.
32bits build should be rock solid (once built in release).

(I have activate the issue tracker for this repo)
