This comes from the stub-chown part here:

FreeCAD-snap/snap/snapcraft.yaml

Lines 138 to 145 in 392dca0

	stub-chown:
	plugin: meson
	source: $CRAFT_PROJECT_DIR/snap/local/stub-chown
	source-type: local
	build-packages:
	- meson
	meson-parameters:
	- --prefix=/usr

FreeCAD-snap/snap/snapcraft.yaml

Line 85 in 392dca0

LD_PRELOAD: $SNAP/usr/lib/$CRAFT_ARCH_TRIPLET_BUILD_FOR/libstubchown.so

I do not understand why it's needed, or if it's still needed. It looks like a stub to bring a modified version of the kernel's chown command. I did not find any references of other snaps doing this.

FreeCAD-snap/snap/local/stub-chown/stub-chown.c

Lines 1 to 10 in 392dca0

	#include <sys/types.h>
	#include <stdio.h>
	int chown(const char *pathname,
	uid_t owner,
	gid_t group)
	{
	fprintf(stderr, "stub-chown: Stubbed out attempt to chown '%s'\n", pathname);
	return 0;
	}

The actual warning comes from how snapcraft's meson plugin invokes meson. It would look like it's calling meson instead of meson setup.

This is how the snap sets up meson's build file. There's not much we can do about that warning here:

FreeCAD-snap/snap/local/stub-chown/meson.build

Lines 1 to 4 in 392dca0

	project('stub-chown', 'c')
	src = 'stub-chown.c'
	shared_library('stubchown', src, install : true)

I'm not sure if this would work, but perhaps modifying the meson-parameters in the snapcraft.yaml file?

-   meson-parameters: 
-     - --prefix=/usr 
+   meson-parameters: 
+     - setup --prefix=/usr 

But first we'd need to understand if/why the stub-chown part is needed. We might be able to remove it altogether and reduce the complexity of the snap.
