Fix builds on FreeBSD, OpenBSD, and NetBSD by Kaleb-Reid · Pull Request #114233 · godotengine/godot

Kaleb-Reid · 2025-12-20T10:45:50Z

I was able to compile from scratch on FreeBSD 15.0 / 13.5, OpenBSD 7.8 / 7.7, and NetBSD 10.1 without disabling anything using this pr.

I briefly ran the editor on OpenBSD, created a new project, and add a couple nodes in 3D. I currently do not have access to a FreeBSD or NetBSD machine with a display out so I have only briefly tested them in headless mode.

Basically what I've done when compiling under bsd:

Use bsd joystick implementation in sdl.
Disabled haptics.
Disabled camera module.
Dont set HAVE_SECURE_GETENV for openxr.
Modify linker flags and fix clang / gcc detection.
Directly define mouse button codes so that input-event-codes.h can be removed because it is not available on NetBSD.
Replace a few system apis with their bsd counterparts.
Fix some warnings which become errors when compiling in dev mode.
Replace some problem instances of size_t with uint64_t in the wayland implementation instead of adding a long constructor to Variant due to OpenBSD defining size_t as long. The two wayland files are the only ones in the project with this problem so it seems overkill to change Variant to fix the problem.

Also the issue in #101588 (comment) where the editor would not compile is due to the process memory limit being relatively low in OpenBSD by default (1.5GB for users with the staff class). I also had this failure around the same part, but if you raise the limit (e.g. ulimit -d 10000000), then you can compile fine.

Fixes #55192
Fixes #92130
Fixes #110606
Supersedes #101588

I'm moving the changes to the wrappers to a new pr, this pr still fixes compilation but optional runtime libraries will not be found on OpenBSD or NetBSD.

@DeanLemans I'm essentially just waiting for reviews.

 	int count = swapctl(SWAP_NSWAP, 0, 0);
 	if (count > 0) {
-		swapent swap_info[count];
+		swapent *swap_info = (swapent *)memalloc(count * sizeof(swapent));


CC @bruvzg to review this bit.

It seems fine, but not sure why having it on stack was an issue, was it too large because of PATH_MAX?

@bruvzg This triggered a compiler warning for having a variable length array, which in dev mode aborted compilation.

Did you look into contributing this upstream to Embree?

@akien-mga I didn't bother to because the OpenBSD implementations of the functions are just dummy implementations. Until now so were the NetBSD ones, but I just changed them to be the same as the Linux implementations as NetBSD seems to support the same interfaces as Linux in this case.

+    return "gcc" in os.path.basename(env["CC"]) or (
+        sys.platform.startswith("netbsd") and os.path.basename(env["CC"] == "cc")
+    )


 def using_clang(env):
-    return "clang" in os.path.basename(env["CC"])
+    return "clang" in os.path.basename(env["CC"]) or (
+        (sys.platform.startswith("freebsd") or sys.platform.startswith("openbsd"))
+        and os.path.basename(env["CC"]) == "cc"
+    )


That sounds quite error prone if either of these *BSD platforms change their default cc compiler in the future. They don't provide gcc and clang binaries?

It's been working in the past without requiring those changes, I wonder why this is needed now.

@akien-mga I may be able to revert the NetBSD one, but the other two are necessary because it was causing builds done with the default system compiler (cc which is a copy of clang) to not be forced as llvm builds which made certain compiler flags not be applied, causing issues such as failing when compiling in dev mode due to missing flags to ignore warnings as well as not adding the clang-specific linker flags for statically linking libc++. If instead we check CXX, I believe only OpenBSD would need a workaround because it's default is c++ which is a copy of clang++.

I've reverted the modification to using_gcc but kept the one to using_clang

I just noticed there's a FreeBSD ports update for 4.6.1. Sharing here just in case you haven't seen it.
