Thanks Rich, that worked. I also had to compile augeas and specify 'AUGEAS_LIBS=~/.local/lib AUGEAS_CFLAGS="-O3"' for it to be picked up. The problem I'm hitting now is: configure: error: libmagic (part of the "file" command) is required. Please install the file devel package I have manually installed the contents of the file-devel RPM and its dependency file-libs into ~/.local/, so I now have libmagic.so under ~/.local/lib64/. Any idea how I can get ./configure to pick this up? I tried LD_LIBRARY_PATH=~/.local/lib64 but this didn't seem to work. I'm hopeful this might be the last piece that's missing!

LIBRARY_PATH=~/.local/lib64 doesn't seem to work either unfortunately (still unable to find libmagic). Any other ideas (even if I need to edit a file and rerun autoconf or something)? Thanks, Lewis On Sat, 1 May 2021 at 20:01, Richard W.M. Jones <rjones(a)redhat.com&gt; wrote:

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 On Sun, 2 May 2021 at 09:28, Richard W.M. Jones <rjones(a)redhat.com&gt; wrote:

I finally have it working! I should have thought of using yumdownloader myself - thanks for that. The other missing piece was needing a supermin appliance binary (guestfs seemed to be trying to use /usr/bin/supermin5 which isn't present for me, and I couldn't work out how to get it to use $PWD/usr/bin/supermin5). Full steps I ended up using: yumdownloader --resolve libguestfs libguestfs-tools-c for rpm in *.rpm; do rpm2cpio "$rpm" | cpio -idmv done curl https://download.libguestfs.org/binaries/appliance/appliance-1.40.1.tar.xz -OL tar -xf appliance-1.40.1.tar.xz LIBGUESTFS_PATH="$PWD/appliance" LD_LIBRARY_PATH="$PWD/usr/lib64" ./usr/bin/virt-cat -a centos7.qcow2 /root/.bashrc PKG_CHECK_MODULES, following examples of other package tests in that file I've created https://github.com/libguestfs/libguestfs/pull/66 with some discussion on the two cases - feel free to edit/decline as you see fit.
