configure already generates this. No idea what "complaining", "extra
preparations", nor "special commands" you mean. (Well, ok, perhaps the
empty files: This just

It should be generated by the macros from build/aclocal.makefile.m4
("These are the facilities for generating Makefile.am.features[...]").
The macros are called by build/configure.ac.features which is
m4_include'd by configure.ac.

So it seems that this needs configure to run. As a side effect this
generates the proper files. Then you need to run automake again so that
the proper Makefile.in is created. Which means you need to run configure
