Hi, maybe a silly question- but I`m not that specialist :-) After configuring Cyrus with default settings, make produces the following: <cut> ### Making all in /home/r2scheik/test/cyrus-imapd-2.0.12/et make[1]: Wechsel in das Verzeichnis Verzeichnis ;/home/r2scheik/test/cyrus-imapd-2.0.12/et+ gcc -c -I/usr/local/include -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 error_message.c In file included from /usr/include/errno.h:36, from internal.h:44, from error_message.c:54: /usr/include/bits/errno.h:25:26: linux/errno.h: Datei oder Verzeichnis nicht gefunden make[1]: *** [error_message.o] Fehler 1 </cut> Can anyone please help me? Thanks, Roland
