the 'hivex' had been installed actually, hivex.x86_64 0:1.2.4-3.el6 and
perl-hivex.x86_64 0:1.2.4-3.el6,
however it just could not be detected.Maybe i should compile one rather than just yum.
I`m not familiar with hivex,as far as i know, it can be used to modify windows registry,
but why the inspection API had been binded with hivex when we might use inspection api
solely with linux os instance image?

Local builds act a bit differently because they contain a hidden
'RPATH' ELF entry:
$ eu-readelf -d ./fish/.libs/lt-guestfish | grep RPATH
RPATH Library rpath: [/home/rjones/d/libguestfs/src/.libs:/usr/local/lib]
This RPATH entry overrides LD_LIBRARY_PATH:
$ LD_LIBRARY_PATH=/usr/lib64 ./fish/.libs/lt-guestfish --version
guestfish 1.17.40
For the builds that we provide in Fedora and RHEL, we strip out RPATH:
$ eu-readelf -d /usr/bin/guestfish | grep RPATH
$ /usr/bin/guestfish --version
/usr/bin/guestfish 1.17.36fedora=17,release=2.fc17
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.
Install the 'hivex-devel' and 'libvirt-devel' packages (from RHEL)
before ./configure && make.
You may be able to do 'yum-builddep libguestfs' to install all the
dependencies; or else read the libguestfs.spec file (BuildRequire lines).

You need 'hivex-devel'.

Because the ./configure test is very simplistic, hivex is required
even if you're only going to inspect Linux guests. In any case,
hivex(-devel) is a simple C library which is very widely available so
this is not really a problem.

I think all the problems occurred above are mainly because of the
uncleaned environment of an old version before the installation . Maybe
I should uninstall and remove all the *guestfs* stuff and figure it out.
And concerning the 'hivex-devel',I really should`ve noticed that there
was no 'hivex-devel' in my yum repo when i yum install '*hivex*'.Then i
solved this with rpm package.
Thank you Rich

I don't want to discourage you from compiling from source. But is
there a particular feature of libguestfs 1.17.40 that you need which
isn't in libguestfs 1.16.19 from here?

OK, 'mount-local' I guess, given the subject line :-)
We should probably make RHEL 6 builds (RPMs) available routinely. It
wouldn't be too hard to add to the automated build system ...

Looking forward to it!
And before that i guess i have to find a way to survive a series of
errors and warning.:-[

Actually there is a particular feature that i wannt try out---
the mount_local api. And i remembered it was added from
1.17.22. As a result i had to gave up the 1.17.17 which had long
been installed but not supportive , and after trials and errors
compiling , i decided to pick up the latest devel version.
And that`s the whole story with this thread :(
At the time it`s not likely to change the rhel6.1 environment to
later version.
any suggestion?

We can probably backport the mount-local API for RHEL 6.4 (around Dec
2012 though). File a bug at http://bugzilla.redhat.com ...
