U
Sorry, ich hatte gerade noch einen Anruf und antworte deshalb erst jetzt.
u.a. in fuse.h :
struct fuse_operations {

* mount option is given.

* open(). This happens if more than one file descriptor refers
* to an opened file due to dup(), dup2() or fork() calls. It is
* not possible to determine if a flush is final, so each flush
* should be treated equally. Multiple write-flush sequences are

Wie gesagt : Das sind die Original-Beispiele.
Könnte es noch an etwas anderem liegen ?
edit :
Mich wundert noch die Anjuta-Nachricht
/usr/bin/create_global_tags.sh: 3:not found
shift: 11:can't shift that many
obwohl die Datei da ist und schon auf rwxr-xr-x steht.
EDIT :
Ich habe die Lösung fürs Compilieren in einem Blog gefunden :
gcc -lfuse -D_FILE_OFFSET_BITS=64 -DFUSE_USE_VERSION=25 hello.c -o hello
Danke noch einmal für die Mühe !!!
