Thanks, once again that seems to have got me past that problem, only for a new one to crop up (this time hivex, which I'm not sure how to build or why it's required on Linux). I take it this isn't really an expected workflow, trying to get the package to build without being able to use a package manager to install the dependencies?

Searching the output from ./configure, I can't yet see any mention of quite a few of the other dependencies listed at https://libguestfs.org/guestfs-building.1.html that may be problematic, so I'm wondering if it's time to throw in the towel for this approach.

All I'm looking for really is a way to programmatically edit a single file in a qcow2 VM image (which I planned to achieve with virt-edit) - is there an easier way to do this? Does virt-edit alone require all these dependencies, or would there be a way to build just virt-edit without pulling apart the build system?

Alternatively, would it be possible/easier to build a static virt-edit binary in a CentOS 7 VM that could simply be copied onto this RHEL 7 machine?

I appreciate your help so far and any further suggestions you might have!

Thanks,
Lewis

Take a look at m4/guestfs-libraries.m4 and change the AC_CHECK_LIB to
PKG_CHECK_MODULES, following examples of other package tests in that
file, then re-run "autoconf".
