[Emc-users] emc2 head broken

[paul_c <pa...@us...>]

Configured emc2 head with the following options:

 --disable-build-documentation --enable-run-in-place 
--with-rtai=/usr/realtime-2.6.16.20-rtai --with-python=/usr/bin/python2.4

Had to remove the -funit-at-a-time flag, not all versions of gcc accept it.
On attempting to run scripts/emc, it failed with:

paul@B5:/tmp/emc2$ scripts/emc

EMC terminated with an error.  You can find more information in the log files
    /home/paul/emc_debug.txt
and
    /home/paul/emc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal


Aside from the fact something is clearly wrong, log files should be written 
to /tmp or /var/log in accordance with the LFSH.

Using configure with --without-rtai or --without-rtlinux still doesn't work, 
and I suspect --enable-simulator will still fail at compile time.
