Returning to KCONFIG :-) I have talked to Debian kconfig-frontends maintainer Philippe Thierry:
https://packages.debian.org/stable/kconfig-frontends He confirmed that kconfig-frontends is abandoned. They use own git repository with version 4.11.0.1 as current: https://salsa.debian.org/philou/kconfig-frontends Debian patches necessary to build are here (some additional patches are necessary to GTK/GDK): https://salsa.debian.org/philou/kconfig-frontends/-/tree/debian/master/debian/patches Espressif repository seems to use older version 4.6: https://github.com/espressif/kconfig-frontends They modified code so it builds with CMake, but only produces kconfig-mconf. I made it work on FreeBSD with cmake part: https://github.com/cederom/kconfig-frontends/commit/c87bd73b50f8f6327672e4fb5f0a2000becfe9c2 kconfig-frontends clearly needs a new upstream and maintainer, also some work to catch up with new frontend libraries. Who could be willing to take that burden? Espressif? Debian? NuttX? On the other hand we have Python's kconfiglib that is well maintained and verified on various platforms and applications (i.e. Zephyr). -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
