Hello Guix! As stikonas (Andrius Štikonas) rightfully pointed out on #guix, Flex and Bison are currently not entirely built from source in Guix: their source tarballs contain Flex- and/or Bison-generated files.
The problem and a solution are described here: https://gitlab.com/giomasce/nbs/ The “live-bootstrap” project also implements a multi-stage bootstrap: https://github.com/fosslinux/live-bootstrap/blob/master/sysa/heirloom-devtools-070527/heirloom-devtools-070527.kaem https://github.com/fosslinux/live-bootstrap/blob/master/sysa/flex-2.5.11/flex-2.5.11.sh https://github.com/fosslinux/live-bootstrap/blob/master/sysa/flex-2.6.4/flex-2.6.4.sh https://github.com/fosslinux/live-bootstrap/tree/master/sysa/bison-3.4.1 Let’s follow their lead on the next core-updates cycle. Thanks stikonas for the links! Ludo’.
