hi All, The system is Ubuntu 12.04 I download and extracted source packages of samba and glusterfs and I built glusterfs, so I get the right necessary structure: glusterfs version is 3.4 and it's from ppa. # ls /data/gluster/glusterfs-3.4.0final/debian/tmp/usr/include/glusterfs/api/glfs.h /data/gluster/glusterfs-3.4.0final/debian/tmp/usr/include/glusterfs/api/glfs.h Unfortunately I'm getting this error: # ./configure --with-samba-source=/data/samba/samba-3.6.3/ --with-glusterfs=/data/gluster/glusterfs-3.4.0final/debian/tmp/usr/include/glusterfs/ checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking for a BSD-compatible install... /usr/bin/install -c checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking how to run the C preprocessor... gcc -E checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking api/glfs.h usability... no checking api/glfs.h presence... no checking for api/glfs.h... no Cannot find api/glfs.h. Please specify --with-glusterfs=dir if necessary I don't see, what its problem is? Thanks, tamas
