Starting With one of the commits since yesterday evening I get this when I try to run ~/guix_dev clean OR ~/guix_dev enter and then "make". An excerpt from my guix_dev: clean) make clean-recursive ;; enter) guix environment --fallback --ad-hoc guix autoconf automake@1.15.1 make guile guile-ssh pkg-config gcc-toolchain libgcrypt gnutls guile-json zlib bzip2 sqlite help2man gettext texinfo guile-git ;; This happens with automake AND automake@1.15.1, yesterday it used to work as it is (without specifying automake 1.15.1). user@abyayala ~/src/guix/guix [env]$ ~/guix_dev clean cd . && /bin/sh /home/user/src/guix/guix/build-aux/missing automake-1.15 --gnu Makefile configure.ac:11: error: version mismatch. This is Automake 1.15.1, configure.ac:11: but the definition used by this AM_INIT_AUTOMAKE configure.ac:11: comes from Automake 1.15. You should recreate configure.ac:11: aclocal.m4 with aclocal and run automake again. configure.ac:23: warning: The 'AM_PROG_MKDIR_P' macro is deprecated, and its use is discouraged. configure.ac:23: You should use the Autoconf-provided 'AC_PROG_MKDIR_P' macro instead, configure.ac:23: and use '$(MKDIR_P)' instead of '$(mkdir_p)'in your Makefile.am files. Makefile.am:491: warning: AM_GNU_GETTEXT used but 'po' not in SUBDIRS WARNING: 'automake-1.15' is probably too old. You should only need it if you modified 'Makefile.am' or 'configure.ac' or m4 files included by 'configure.ac'. The 'automake' program is part of the GNU Automake package: It also requires GNU Autoconf, GNU m4 and Perl in order to run: make: *** [Makefile:2956: Makefile.in] Error 63 So what am I supposed to do now? -- ng0 GnuPG: A88C8ADD129828D7EAC02E52E22F9BBFEE348588 GnuPG: https://n0is.noblogs.org/my-keys https://www.infotropique.org https://krosos.org
