$gcc -Wall passthrough_fh.c `pkg-config fuse3 --cflags --libs` -lulockmgr -o passthrough_fh
Package fuse3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `fuse3.pc'
to the PKG_CONFIG_PATH environment variable
No package 'fuse3' found
passthrough_fh.c:34:10: fatal error: fuse.h: No such file or directory
   34 | #include <fuse.h>
      |          ^~~~~~~~
compilation terminated.

解决方法

1

$cp meson-private/fuse3.pc /usr/lib/pkgconfig
