2.6~pre.
I dont know what system You have, but if it is updated, then it is not
fresh dailybuild from
http://cdimage.ubuntu.com/xubuntu/daily-live/current/ .
The problem is :
linuxcnc is compilled on Xubuntu downloaded in januaru, but is NOT
compiled on system downloaded in february.
My script for dependiences is :
#!/bin/bash
if !( ping -c 1 www.google.com ); then
echo "No Internet connection detected."
echo "Connect computer to the Internet before running this script."
echo "Aborted"
exit 0

Some packages are not for linuxcnc, but this is not important.
System downloaded in january works, but system downloaded in february
not works for linuxcnc.
The error is :
Linking classicladder
/usr/bin/ld: objects/hal/classicladder/socket_modbus_master.o: undefined
reference to symbol 'pthread_create@@GLIBC_2.2.5'
/usr/bin/ld: note: 'pthread_create@@GLIBC_2.2.5' is defined in DSO
/lib/x86_64-linux-gnu/libpthread.so.0 so try adding it to the linker
command line
/lib/x86_64-linux-gnu/libpthread.so.0: could not read symbols: Invalid
operation

make: *** [../bin/classicladder] B?a;d 1
make: Opuszczenie katalogu `/opt/linuxcnc.sim/src'
It is problem to write code witch <at> symbol in mail.
I must write pthread_create<at><at>GLIBC_2.2.5 .
All dependiences are installed correctly.
lipthread is libpthread.so.0 --> libpthread-2.15.so
symbol pthread_create<at><at>GLIBC_2.2.5 exist.
In system downloaded in january libraries are 2.13 and compiled linuxcnc
without errors.
In system downloaded in february libraries are 2.15 and compiled
linuxcnc with described error.
Well, english is not my native language, but problem is simply.
Newest libraries not support old code of linuxcnc.

I just did several builds on a Precise machine, updated today. I built 2.5 and
master. No problems.

Our buildbot builds and tests every commit to LinuxCNC on Ubuntu Precise, both
in 32-bit and 64-bit, and we are not seeing any problems there. I think your
build machine is set up wrong somehow.
Do you have all the build dependencies installed correctly? Try this (from the
top-level directory of a git clone of linuxcnc):
cd debian
./configure sim
cd ..
dpkg-checkbuilddeps

I have no libmodbus in my system.
Installing libmodbus-dev gets no changes.
There are two questions :
1. Why ?
2. Why when linking classicladder and in socket_modbus_master.o ?
1.
It is not first and nod last surprise from gcc developers.
They are rebuilding libraries without back compability.
2.
In my opinion it is bad code in linuxcnc.
This code was work, but will not
12.04 is LTS and Xubuntu is light and simple like old Gnome.
It is good choice get Xubuntu Precise for linuxcnc platform.
In my opinion linuxcnc must work on this system.
On 32 and 64 bit.
