Errors while building Godot 4 version

[WaltonSimons]

Is the current version of godot4 branch supposed to be build-ready? I keep getting errors when trying to build godot with voxel module. I'm building arm64 version on macos. Here are the logs:

[Zylann]

The first errors seem to occur in FastNoise2, which I have no idea why. It's trying to include x86 symbols but fails because I guess it's actually not on x86. Unfortunately the official library uses CMake and couldn't get static linking to work yet, so I currently translated it to SCons to keep the build system unified, however I could never test it on Mac OS (and even seeing your logs I have no idea what I should change). Did it work for you before?

In other news, Godot 4 just replaced OpenSimplexNoise with FastNoiseLite. That makes support for this class in the module irrelevant and won't compile anymore, but it also directly conflicts with my own implementation of FastNoiseLite. It should be prefixed or maybe removed (I consider the former because after seeing Godot's version, I suspect it might be slightly slower due to lack of inlining, especially in builds with float=64 because it uses real_t everywhere, not just in coordinates. It also lacks separate warp functions and get_noise functions aren't const for some reason. But since there is FastNoise2 now, it's probably not a big deal to remove it?).

[Zylann]

Just got some insight from Auburn, FastNoise2 doesn't work on arm64 yet. It can only do x86. So you need either to switch to an x86 target, or you could turn off FastNoise2 support in SCsub. It is also possible to build FastNoise2 without SIMD support but it would be much slower.

The second problem is still valid tho, I'll work on that when I get the time.

[Zylann]

Another thing I noticed:

In file included from modules/voxel/constants/../util/math/vector3i.h:5:
modules/voxel/constants/../util/math/funcs.h:164:10: error: member access into incomplete type 'const Vector3i'
        return s.x >= 0 && s.y >= 0 && s.z >= 0;

This suggests you are compiling with the wrong Godot version? Because Vector3i should definitely be defined here. Also when you say godot4 branch, do not use the branch that is actually named godot4. That was a very old one. For Godot 4, you should use the master branch.

[WaltonSimons]

Many thanks for your help. I reverted godot to version that still supports OpenSimplexNoise (v4.0.alpha.custom_build [45ec0e31c]) and turned off FastNoise2 in SCsub. Most errors are now gone, but I'm still encountering the one related to Vector3i for some reason:

modules/voxel/terrain/fixed_lod/../../storage/voxel_data_map.h:143:18: error: no matching constructor for initialization of 'const Vector3i'
                const Vector3i block_size(get_block_size());

Interesting you got this error. Neither MSVC nor GCC on Github actions caught this one. I used to have a custom Vector3i before Godot adds its own, but Godot doesn't have a constructor converting from a single int. I'll fix that.

Edit: error and warnings should be fixed after fd0f524bf5252c1614ad87aa563b3efbf2e79b32

I still need to address the FastNoiseLite problem.

[Zylann]

master should build with FastNoiseLite now after e0008d3335cdc7ecd4b7fd53a5ec86e9fcb420b7

Unfortunately I'm still encountering errors 🙁

Your compiler seems to be really picky compared to GCC and MSVC... that's another bit they never picked up. It's like Godot configures different warning levels for every compiler?

modules/voxel/server/load_all_blocks_data_task.cpp:17:88: error: conversion from 'std::vector::size_type' (aka 'unsigned long') to 'const Variant' is ambiguous PRINT_VERBOSE(String("Loaded {0} blocks for volume {1}").format(varray(_result.blocks.size(), volume_id)));

This one is yet another occurrence of https://github.com/godotengine/godot/issues/36690, but it can be worked around.

Should be fixed in 15bf2a6980037eb42c7995a7addf034466b54bc0

[WaltonSimons]

It works now. Thank you so much!
