Hi, I have an old bison checkout, without modifications. Now updated it using "git pull", then ran $ ./bootstrap
The run ends with Don't forget to - "include gnulib.mk" from within "lib/Makefile.am", - add "gnulib-po/Makefile.in" to AC_CONFIG_FILES in ./configure.ac, - mention "gnulib-po" in SUBDIRS in Makefile.am, - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am, - mention "m4/gnulib-cache.m4" in EXTRA_DIST in Makefile.am, - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC_STDC, - invoke gl_INIT in ./configure.ac. prefix=lib/ ./bootstrap: some git submodules are not initialized. Run 'git submodule init' and bootstrap again. So I do this: $ git submodule init $ ./bootstrap ... ./bootstrap: some git submodules are not initialized. Run 'git submodule init' and bootstrap again. $ echo $? 1 $ git status On branch master Your branch is up-to-date with 'origin/master'. nothing to commit, working directory clean $ git submodule d279bc6d9f9323e19ad8c32b6d12ff96dfb0f5ba gnulib (v0.1-3322-gd279bc6) -babc8660d5a7561ed7e99e09aeabffaccfe06d6d submodules/autoconf I'm stuck here. There was a similar report about GNUTLS here: https://lists.gnu.org/archive/html/bug-gnulib/2019-03/msg00001.html The cause is probably in gnulib: https://lists.gnu.org/archive/html/bug-gnulib/2019-01/msg00000.html Bruno
