cross-compile diamondback ROS for Nao 1.10 issues...

edit

Trying to follow instructions at http://www.ros.org/wiki/nao/Tutorials/Cross-Compiling#A1.10.2B-_and_Diamondback

Not exactly sure how to interleave 1.10 instructions with original instructions... that might be the issue.

In addition to some minor obstacles (detailed below), I was ultimately stymied by not being able to build apr-util (could not link to crti.o)

Help!

Thanks,

Setup is Ubuntu 10.10, Nao H25 and nao-cross-toolchain 1.10.52 ( note to others: toolchain is not in the SDK, and is hard to find on new web page, but here's a link: http://users.aldebaran-robotics.com/index.php?option=com_docman&task=cat_view&gid=50 )

Notes:

• needed libmpfr1ldbl package as a prerequisite ( sudo apt-get install libmpfr1ldbl )
• (9.4) Get rosinstall file:
  • sudo easy_install -U rosinstall
  • wget "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=diamondback&variant=ros-base&overlay=no" -O diamondback.rosinstall
  • (as per http://www.ros.org/wiki/diamondback/Installation/rosinstall )
• (9.7) Patch rosbuild - with what patch?
• (9.8) Compile ROS - doesn't this require apr, etc. to be built first? my build complained...
• (4) Cross-compiling of non-ROS modules:
  • apr and apr-util have new versions; I just grabbed the latest ones listed at http://www.powertech.no/apache/dist/apr/
  • As predicted, upon building apr-util, I got error: "cross/geode/bin/../lib/gcc/i586-linux/4.3.3/../../../../i586-linux/bin/ld: crti.o: No such file: No such file or directory" ; however, copying files into /home/opennao/opennao-1-4-x/build/tmp/ did not work. I noticed (via grep) that the nao cross toolchain referred to 1-9-x, so I tried that path instead, but to no avail.
