Setup Dual Head for EeePC with Ubuntu

1. refer to How to setup Dual Head for Intel Graphics with RandR 1.2
2. edit /etc/X11/xorg.conf for Section "Screen"
   SubSection "Display"
   Depth 32
   Virtual 2048 2048
   EndSubSection
   
3. restart X with "ctrl-alt-backspace"
4. confirm the maximum "Screen 0" size is 2048x2048 with "xrandr -q"
5. set the screen layout
   xrandr --output VGA --pos 0x0
   xrandr --output LVDS --pos 0x1024

EeePC model: 904
Linux distribution: Ubuntu 8.04 LTS

Build EMC2 on CentOS 5.3 (x86_64)

Required packages:

• pth-devel
• bwidget
• tcl-devel
• tk-devel
• libtermcap-devel
  
• readline-devel
• libXmu-devel
• tkinter
  

sudo yum install pth-devel bwidget tcl-devel tk-devel libtermcap-devel readline-devel libXmu-devel tkinter
cd /usr/share/tcl8.4; sudo ln -sf ../../share/bwidget1.8.0 BWidget

edit src/hal/utils/Submakefile

1. locate for ../bin/halrmt
2. remove $(READLINE_LIBS) from its dependent list
3. add $(READLINE_LIBS) to "@$(CXX) $(LDFLAGS) -o $@ $^ -lpthread"

../bin/halrmt: $(call TOOBJS, $(HALRMTSRCS)) ../lib/libemcini.so.0 ../lib/libnml.so.0 ../lib/libemchal.so.0
 $(ECHO) Linking $(notdir $@)
 @$(CXX) $(LDFLAGS) -o $@ $^ -lpthread $(READLINE_LIBS)

cd src
./configure --enable-simulator --enable-run-in-place
make
cd ../; . ./scripts/emc-environment
unset LD_LIBRARY_PATH # to disable incorrect xilinx library search path
emc

Build EMC2 on Windwos

1. GNU PTH Library
2. BWidget:

• download BWidget-*.tar.bz2 from tclib.sf.net
• uncompress and copy it to /usr/share/BWidget
• verify the installation with 'tclsh'
• % set auto_path
• % package require BWidget

Build emc2

1. cd src
2. ./configure --enable-simulator --enable-run-in-place
3. make (stuck at here: cannot build libnml on Windows)
   # Before running the software, set the emc environment:
   # . (top dir)/scripts/emc-environment
   # To run the software type
   # emc
4. libnml is forked from rcslib
5. rcslib can be built with MinGW; cannot be built with cygwin
6. replace libnml with rcslib?
7. port libnml to cygwin?
   
8. skip emc2 and try orocos?
