On Ubuntu 23.10 configure fails for a git checkout:

$ git clone https://github.com/resurrecting-open-source-projects/dcfldd.git
$ cd dcfldd/
$ ./autogen.sh 
configure.ac:48: warning: The macro `AC_HELP_STRING' is obsolete.
configure.ac:48: You should run autoupdate.
./lib/autoconf/general.m4:204: AC_HELP_STRING is expanded from...
configure.ac:48: the top level
configure.ac:33: installing './compile'
configure.ac:29: installing './config.guess'
configure.ac:29: installing './config.sub'
configure.ac:26: installing './install-sh'
configure.ac:26: installing './missing'
src/Makefile.am: installing './depcomp'

Done. You can use the 'clean' option to vanish the source code.

Thanks for reporting this issue. pkg-config is required during build since https://github.com/resurrecting-open-source-projects/dcfldd/commit/055d4257123736f5f14b7937130607418a3eb378. Please, install pkg-config and execute ./autogen.sh and ./configure again. I tested it here and that solved the problem. Please let us know if it worked for you. Also, I'm going to update the documentation on dependencies.

I have retested with installing pkg-config:

schroot-wrapper -c mantic -p autoconf,automake,ca-certificates,pkg-config,git

Then running ./configure works. I suggest to add a check to autogen.sh for pkg-config being present.
