[etherlab-users] Problem building master

[John Erlandsson]

Hi!

Having some problems building the master on fedora 19

autoreconf fails with the message:
+ touch ChangeLog
+ autoreconf -i
automake: warnings are treated as errors
/usr/share/automake-1.13/am/ltlibrary.am: warning: 'libethercat.la': 
linking libtool libraries using a non-POSIX
/usr/share/automake-1.13/am/ltlibrary.am: archiver requires 'AM_PROG_AR' 
in 'configure.ac'
lib/Makefile.am:33:   while processing Libtool library 'libethercat.la'
autoreconf: automake failed with exit status: 1*
*

I made this change to configure.ac

*** configure.ac.orig    2013-11-29 13:50:20.469640086 +0100
--- configure.ac    2013-11-28 03:11:59.919355571 +0100
*************** AC_CONFIG_MACRO_DIR([m4])
*** 40,45 ****
--- 40,46 ----
   # Global
#------------------------------------------------------------------------------

+ AM_PROG_AR
   AC_PROG_CXX
   AC_PROG_LIBTOOL
   AM_PROG_CC_C_O

And the bootstrap script finished without errors.

#./configure 
--with-linux-dir=/usr/src/kernels/3.10.20-200.rt17.1.fc19.ccrma.i686.rt 
--enable-8139too=no --enable-generic=yes --enable-cycles=yes
runs without any problems

#make && make doc
runs without any problems.

make modules fails with the message:

I suspect that my kernel version is too new. Can someone confirm?

Thanks...
