Initially observed as a failure on nix-2.21.0 upstream package (not in ::gentoo). Self-contained example of cat/bug-0 package: ```ebuild # $ cat bug-0.ebuild EAPI=8 SLOT=0 inherit autotools src_unpack () { mkdir -p "$S" } src_prepare() { mkdir -p config cat > configure.ac <<-EOF AC_INIT([bug], [0], [https://dev.null]) AC_CONFIG_AUX_DIR([config]) AC_CANONICAL_HOST AC_OUTPUT EOF eapply_user eautoreconf find } ``` It's build fails as: ``` $ ebuild cat/bug/bug-0.ebuild clean configure Appending /bound/nix-guix-gentoo to PORTDIR_OVERLAY... >>> Unpacking source... >>> Source unpacked in /dev/shm/portage/cat/bug-0/work >>> Preparing source in /dev/shm/portage/cat/bug-0/work/bug-0 ... * Running eautoreconf in '/dev/shm/portage/cat/bug-0/work/bug-0' ... * Running 'aclocal --system-acdir=/dev/shm/portage/cat/bug-0/temp/aclocal' ...

Please attach the following file when seeking support: !!! /dev/shm/portage/cat/bug-0/work/bug-0/config.log ``` It fails because autotools.eclass places config.guess config.sub not to expected `config/` firectory set by AC_CONFIG_AUX_DIR, but to the root directory. For comparison this is how configuration succeeds when ran manually: ``` $ mkdir /tmp/b $ pushd /tmp/b $ mkdir -p config $ cat > configure.ac <<-EOF AC_INIT([bug], [0], [https://dev.null]) AC_CONFIG_AUX_DIR([config]) AC_CANONICAL_HOST AC_OUTPUT EOF $ autoreconf -ifv autoreconf-2.72: export WARNINGS= autoreconf-2.72: Entering directory '.' autoreconf-2.72: configure.ac: not using Gettext autoreconf-2.72: running: aclocal --force autoreconf-2.72: configure.ac: tracing autoreconf-2.72: configure.ac: not using Libtool autoreconf-2.72: configure.ac: not using Intltool autoreconf-2.72: configure.ac: not using Gtkdoc autoreconf-2.72: running: /usr/bin/autoconf-2.72 --force autoreconf-2.72: configure.ac: not using Autoheader autoreconf-2.72: configure.ac: not using Automake autoreconf-2.72: 'config/config.sub' is created autoreconf-2.72: 'config/config.guess' is created autoreconf-2.72: Leaving directory '.' $ find . ./config ./config/config.sub ./config/config.guess ./configure.ac ./autom4te.cache ./autom4te.cache/requests ./autom4te.cache/traces.0 ./autom4te.cache/output.0 ./autom4te.cache/traces.1 ./autom4te.cache/output.1 ./autom4te.cache/traces.2 ./autom4te.cache/output.2 ./configure $ ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --datarootdir=/usr/share --docdir=/usr/share/doc/bug-0 --htmldir=/usr/share/doc/bug-0/html --libdir=/usr/lib64 configure: loading site script /usr/share/config.site configure: loading site script /usr/share/config.site.d/80crossdev.conf checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu configure: creating ./config.status ``` Note how `autoreconf` places files to config/ and ./configure succeeds. I think `eautoreconf` should do the same.
