Compiling ROS stack openni_kinect/openni_tracker

While compiling openni_tracker, the compiler cannot find the OpenNI headers.

Append the following line to openni_tracker's CMakeLists.txt

include_directories(/usr/include/ni)

ROS kdl patch failure

While compiling kdl, *make* tries to apply total.patch. However, it is already patched.

  Makefile:61: warning: overriding recipe for target `clean'
  /usr/local/opt/ros/ros/core/mk/cmake.mk:24: warning: ignoring old recipe for target `clean'

Comment out the following line in *Makefile*. Like so:

#cd $(SOURCE_DIR) && patch -p0 < ../../$(PATCH)

Then kdl should compile.

ROS pcl_ros fails to compile with GCC 4.6

Error:
/usr/local/opt/ros/perception_pcl/pcl/include/pcl/ros/conversions.h:284:9: error: taking address of temporary [-fpermissive]

Code fix:
First assign the temporary variable to a local variable. Then reference the address of the local variable. However, this is more complicated with arrays being copied with memcpy. One way is to use a for-loop to replace memcpy.
See patch for a similar error in another library.

Since the change is somewhat drastic, I compiled pcl_ros with gcc-4.5 instead.

# install gcc-4.5
yaourt -S gcc45

Edit perception_pcl/pcl_ros/CMakeLists.txt.
Add the following lines (prefixed with +) near the top, *after* the rosbuild directives.

rosbuild_init()
...

+set (CMAKE_C_COMPILER gcc-4.5)
+set (CMAKE_CXX_COMPILER g++-4.5)

(If the compilers are set before the rosbuild directives, cmake will enter an infinite loop during configuration!)

Then pcl_ros should compile.

Compiling ROS pcl package

The pcl package depends on libhdf5_cpp.so.
However, Archlinux hdf5 does not include libhdf5_cpp.so. See reason.

Therefore, you will need to download and compile hdf5 with the --enable-cxx configure flag.

Download hdf5 source package.

tar -xjf hdf5-1.8.7.tar.bz2
cd hdf5-1.8.7
./configure --prefix=/usr/local --enable-cxx
make
make install

A number of other patches are also necessary when compiling with GCC 4.6.

Compiling ROS pluginlib with boost 1.4.6

pluginlib cannot be compiled with boost 1.4.6, due to changes in API.
Patch can be found at ros-pkg ticket.

Automatic patching will fail, due to later changes to boost_fs_wrapper.cpp.
Apply the patch manually.

Installing irobot_create

The driver is available from the Brown University brown-ros-pkg site.

Download, extract, and compile using ROS.
You should work in a user ROS project directory (such as ~/projects/ros), which as been added to $ROS_PACKAGE_PATH.

cd [ROS project directory]
wget http://brown-ros-pkg.googlecode.com/files/irobot_create_2_1.tar.bz2
tar -xjf irobot_create_2_1.tar.bz2
rosmake irobot_create_2_1

Plug iRobot Create through USB, which should show up as /dev/ttyUSB0
Make ensure you have access to /dev/ttyUSB0.

sudo chmod 666 /dev/ttyUSB0

To test, start roscore and run irobot_create/driver.py

roscore
rosrun irobot_create_2_1 driver.py

In a separate terminal,

# Examine the service
rosservice type tank | rossrv show
# Publish to the service; make the robot spin
rosservice call tank -- 0 -10 10

The last command will instruct the robot to drive the left wheel at -10 mm/s and the right wheel at 10 mm/s, which causes the robot to spin.

Installing ROS bullet

The bullet library does not compile out of the box with GCC 4.6.
The patch is available at:
http://code.google.com/p/bullet/issues/detail?id=284

Download zero_initialize.patch to $ROS_ROOT/../geometry/bullet/
Apply patch and compile.

cd $ROS_ROOT/../geometry/bullet
patch build/bullet_svn/src/BulletSoftBody/btSoftBodyInternals.h -i zero_initialize.patch
rosmake bullet
