Hi,

I usually build the btrfs-progs when it comes out.  I've upgraded from 
Ubuntu 20.04 to 22.04 & I'm having a problem with configure looking for 
ext2fs.  I have e2fsprogs & libext2fs2 installed, but it fails with "No 
package 'ext2fs' found".  What am I missing?

Thanks!

     -John

Is the -devel package installed?

You'll need e2fslibs-dev and other -dev packages.  The easiest way to
get all of these dependencies in one go is probably to get a copy of the
Debian/Ubuntu source package. To do this create "deb-src" lines based on
the "deb" lines in your /etc/apt/sources.list, and

  apt update
  apt source btrfs-progs

Then

  cd btrfs-progs

and finally

  apt build-dep ./

Then build the package as normal.  Note that this won't take care of any
new dependencies (if any) added since the version of btrfs-progs
released with 22.04.

I think synaptic might be able to create the "deb-src" lines, and
there's probably a GUI repository manager program that can do this, but
I'm not familiar with these methods.  I'm sure you'll figure it out
though!  Worst case scenario would be manually installing the -dev
packages for all missing dependencies; there are at least eight or
nine of these.

Cheers,
Nicholas
