I know that the work with UserlandFS/FUSE has been quite frequent lately, so I'm sure Ingo will get this sorted out in a hurry. I still wanted to point it out though in case it slips through the cracks. It appears that FUSEFileSystem.cpp includes FUSEEntry.h, but that file isn't present in the fuse dir. Here is a small snippet from the build log... C++ generated/objects/haiku/x86/release/add-ons/kernel/file_systems/userlandfs/server/fuse/FUSEFileSystem.o In file included from src/add-ons/kernel/file_systems/userlandfs/server/fuse/FUSEFileSystem.cpp:14: src/add-ons/kernel/file_systems/userlandfs/server/fuse/FUSEVolume.h:13: FUSEEntry.h: No such file or directory Some more problems occur after that, but I believe they are mostly (or all) due to the missing include. r29618 builds just fine. - joe
