installing sim on 12.04. error.
i'm trying to install sim on notebook on ubuntu 12.10 (other versions do not support notebook devices). after ./configure --enable-simulator it says okay to make.
the 'make' result:

With the latest Debian Wheezy, all LinuxCNC builds failed using the default gcc-4.7, throwing errors like the following:
Linking ../rtlib/abs.so
ld -r -o objects/abs.tmp objects/rtobjects/hal/components/abs.o
gcc -shared -Bsymbolic -L/home/maker/linuxcnc-dev.head/lib -Wl,-rpath,/home/maker/linuxcnc-dev.head/lib -o ../rtlib/abs.so objects/abs.tmp -lm

To get a working build (even of unmodified LinuxCNC code) I needed to revert back to gcc-4.6:
sudo aptitude install gcc-4.6 gcc-4.6-base
export CC=gcc-4.6
but it didn't help, the error is the same after changing gcc from 4.7 to 4.6.
but. after export CC=gcc-4.6 gcc -v is still 4.7.
oh, it seems i do not know where should i place
export CC=gcc-4.6
export CXX=g++-4.6created it in src and in linuxcnc-dev, nothing changes.

I am not sure, but I think the 'export' is a shell command that is invoked from the command line, have you tried that?

finally!
cd /usr/bin
sudo ln -s gcc-4.6 gcc
sudo ln -s g++-4.6 g++btw why does it compile all rt modules even in sim configuration?
and please can moderator change in topic name 12.04 on 12.10? somehow I made a mistake.

Download the 2 files and install with pkgtool.
It will set the links for you.
Did a clean compile and got no errors.
Seems to work so far.
I am running Slackware 14
I also had to change line 6 of file: emc2/src/emc/sai/Submakefile
From: LIBREADLINE=-lreadline
To: LIBREADLINE=-lreadline -ltermcap
