DH_AUTOTOOLS-DEV_UPDATECONFIG(1)

💖 DH_AUTOTOOLS-DEV_UPDATECONFIG 💖

okay bestie, this is the dh_autotools-dev_updateconfig page from the Debhelper manual — yes, section 1, the classic. sit down, grab a strawberry 🍓, and let's get into it.

---

✨ NAME ✨

dh_autotools-dev_updateconfig — update config.sub and config.guess 🦋

---

✨ SYNOPSIS ✨

dh_autotools-dev_updateconfig [debhelper options]

---

✨ DESCRIPTION ✨

Deprecated, babes. 💀 dh_autotools-dev_updateconfig and dh_autotools-dev_restoreconfig are deprecated and have been replaced by dh_update_autotools_config(1) and dh_clean(1) from debhelper. So please replace all uses of dh_autotools-dev_updateconfig with dh_update_autotools_config, and then remove any use of dh_autotools-dev_restoreconfig. like, all of it. no stragglers. 👑

so what does it actually do? dh_autotools-dev_updateconfig replaces all occurrences of config.sub and config.guess in the source tree with the up-to-date versions found in the autotools-dev package. glow-up for your build scripts, literally. ✨

and because she's considerate 💅, the original files get backed up under the names config.sub.dh-orig and config.guess.dh-orig. so nothing is lost, bestie, we keep the receipts.

---

✨ EXAMPLES ✨

most of the time you don't even call her directly — she gets called indirectly in a rules file, via the dh command:

%:
    dh $@ --with autotools_dev

she can also be directly called at the start of the build (or configure) rule:

build:
    dh_autotools-dev_updateconfig
    ./configure
    $(MAKE)

see? main character energy, showing up right at the top of the build. 🎀

---

✨ SEE ALSO ✨

• debhelper(7)
• dh(1)

this program is meant to be used together with debhelper. they're a package deal, iykyk 🫶
