Hi, I am trying to enable ZRTP support in FS, following the instructions given at http://wiki.freeswitch.org/wiki/ZRTP. Upon executing Step 4, i get following error, afterwords it starts some configure script. root@slave:/usr/src/svn-src/freeswitch# sh build/buildzrtp.sh tar: libzrtp-0.81.514.tar.gz: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: Child returned status 2 tar: Error exit delayed from previous errors cd: 3: can't cd to libzrtp-0.81.514 build/buildzrtp.sh: 4: cannot open ../patches/zrtp_bnlib_pic.diff: No such file cd: 5: can't cd to projects/gnu/ checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... no checking for mawk... mawk checking whether make sets $(MAKE)... yes checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking for gcc... gcc ....
