Hi all When integrating gnulib in liblouis a changed a few things with regards to m4 macro location. In particular I added the following to configure.ac
AC_CONFIG_MACRO_DIR([m4]) and the following to Makefile.am ACLOCAL_AMFLAGS = -I m4 -I gnulib/m4 I also create an empty m4 directory. Now, autoreconf (--force --install) places some libtool m4 macros, like libtool.m4, etc, in there. When I do make dist the m4 directory is automatically included in the tarball (without mentioning m4 anywhere in a Makefile.am as a SUBDIRS). Make distcheck and everybody else is happy. However, for an other dev, who is using libtool 1.5.22, autoreconf 2.59 and automake 1.9.6, make distcheck is failing because the m4 directory is not included in the tarball. Now, I could probably simply add m4 to the SUBDIRS and add an empty Makefile.am to m4. This might solve the problem, but this doesn't seem to be standard practice and I'm trying to understand what is going on here. How is the m4 directory included in the tarball? How does automake know that it has to include it? Was this functionality missing in an older automake? And finally: Is the right way to fix this really to add the m4 directory to SUBDIRS? Thanks Christian
