When I run $ ./gnulib-tool --create-testdir --with-tests --dir=/tmp/testdir1
I get these warnings, among others: gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: error gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: getprogname gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: gettime gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: strftime gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: time_rz gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: timespec gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: xalloc gnulib-tool: warning: module parse-datetime depends on a module with an incompatible license: xalloc-die These were introduced on 2015-11-24 http://lists.gnu.org/archive/html/bug-gnulib/2015-11/msg00048.html The ostree people work around this warning by not using gnulib-tool. They just copied the files lib/parse-datetime.[hy] and edited them to use g_malloc instead of xmalloc. I would like to silence this warning, while at the same time not change the actual license of the module. Here's a proposed patch. A quick hack; I hope we won't have this situation more often. 2016-10-15 Bruno Haible <br...@clisp.org> Avoid gnulib-tool warnings about the dependencies of 'parse-datetime'. * gnulib-tool (func_get_license): Special-case the 'parse-datetime' module. diff --git a/gnulib-tool b/gnulib-tool index 45d5fe0..8f74f9c 100755 --- a/gnulib-tool +++ b/gnulib-tool @@ -2570,11 +2570,21 @@ func_get_license () fi ;; esac - { - func_get_license_raw "$1" - # The default is GPL. - echo "GPL" - } | sed -e 's,^ *$,,' | sed -e 1q + case "$1" in + parse-datetime ) + # These modules are under a weaker license only for the purpose of some + # users who hand-edit it and don't use gnulib-tool.
