[Libguestfs] 回复： guestfs_mount_local* api undefined symbols

Thank you Rich, I checked the version and found that it printed an old 1.17.17 version which was deployed before. But I remembered i did check the version in guestfish shell and it said 1.17.40 before that，then i totally ignored the fact i had another version involved. I`ve changed the LD_LIBRARY_PATH and the "undefined symbol" error disappeared.But some "inspection API not available because of compiled without hivex library" pops up.I`ll check this out later. thank you again ;) Nok ------------------ 原始邮件 ------------------ 发件人: "Richard W.M.

The symptoms sound like you're compiling your program against libguestfs 1.17.40, but you're running your program against an earlier libguestfs library (maybe the one installed in RHEL 6?). This installs libguestfs in /usr/local. The one from RHEL 6 will be in /usr. You might want to set 'LD_LIBRARY_PATH' so that the program uses the /usr/local copy, ie: LD_LIBRARY_PATH=/usr/local/lib ./prog By the way, it's not necessarily safe to mix'n'match libraries, daemons and appliances like you're trying to do here. The protocol used between the library and the daemon has changed since RHEL 6.2. If you are using libguestfs 1.16.19 (from [1]) then it'll probably work for the majority of features. Earlier versions, probably not. If you don't want to compile the right daemon + appliance on RHEL 6, you can copy an appliance from a Fedora 17+ machine. See the instructions here: http://libguestfs.org/libguestfs-make-fixed-appliance.1.html http://libguestfs.org/download/binaries/appliance/ Also you can modify your program so it prints out the version of libguestfs that it's using: http://libguestfs.org/guestfs.3.html#guestfs_version #include <stdio.h> #include <inttypes.h> #include <guestfs.h> //... guestfs_h *g = guestfs_create (); struct guestfs_version *vers = guestfs_version (g); printf ("version = %" PRIi64 ".%" PRIi64 ".%" PRIi64 ".%s", vers->major, vers->minor, vers->release, vers->extra); Rich.
