Hello list,

I'm having trouble building the EtherCAT Master. ./bootstrap says:

+ touch ChangeLog
+ autoreconf -i
automake: warnings are treated as errors
/usr/share/automake-1.14/am/ltlibrary.am: warning: 'libethercat.la':
linking libtool libraries using a non-POSIX
/usr/share/automake-1.14/am/ltlibrary.am: archiver requires 'AM_PROG_AR' in
lib/Makefile.am:33:   while processing Libtool library 'libethercat.la'
tool/Makefile.am:38: warning: source file '../master/soe_errors.c' is in a
tool/Makefile.am:38: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the
automake: automake option hasn't been enabled.  For now, the corresponding
automake: object file(s) will be placed in the top-level directory.
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout
automake: project, to avoid future incompatibilities.
autoreconf: automake failed with exit status: 1

Same thing happens with the default dev branch after checking out the
Mercurial repo, as well as after switching to stable-1.5.

Before I start poking around hoping to get this working, can anyone with
knowledge of the build process advice?
