Hi,

we have been trying to convert a human model from collada to urdf. The model was exported from within blender and when we try to use the urdf_collada converter that comes with ros we run into the following error:

jworch@jawo:~/makehuman/export$ rosrun collada_urdf collada_to_urdf test.dae
;; Input file is: test.dae
[ERROR] [1399980598.886927868]: COLLADA error: Trying to load an invalid COLLADA version for this DOM build!
[ERROR] [1399980598.895890126]: COLLADA error: Failed to load XML document from memory
ERROR: Model Parsing the xml failed

Here you can find the collada file we used. Any idea on how to fix this?

I just figured out that you can directly c&p the following into the addressbar of your browser: build.pointclouds.org/overview.html then, below the login button, there is a link "login as guest". That will lead you to an overview of the buildfarm of pcl, where the status of all repos is listed.

Take a look at the answer given by Georg Bartels or the link he posted to an issue at github. Those two "strategies" to solve the problem seems to be the right way to find the path to script.

It seems as if the current repository status is not being able to be build. Take a look at (not enough karma...). Google for build.pointclouds.org/overview.html

I was able to "fix" the problem. The problem is that

rospack find rosbuild

points to

/opt/ros/groovy/share/rosbuild/

but the python script is located in

/opt/ros/groovy/share/ros/core/rosbuild/bin/

So my workaround was to create the bin folder and create a symbolic link to the python script. Is there any better solution than this workaround, because to me it seems not to be the final solution but more a bad hack.

Hi,

when trying to compile a package on groovy I get the following error.

make clean
  make[1]: Entering directory `/home/jworch/groovy_workspace/sandbox/cram_core/3rdparty/alexandria'
  rm -rf alexandria asdf alexandria-20110210.tar.bz2

[ rosmake ] Halting due to failure in package alexandria.

It it is supposed to pull a tarball which is not held in the package repository. It worked on fuerte and I guess it fails because of the missing *.py file. Is there any substitute on groovy for that file or another/better way to solve this problem? Thanks in advance
