ZED2 The "new" xacro script is the old xacro.py renamed and lives in the For the additional commands proposed in ros/ros_comm#228 which would enable an arbitrary location of the executable in the source package it was not possible to reach a consensus so it will likely not be merged at all. However, the contents in the ${} dont have to only be a property, which brings us to our next point You can build up arbitrarily complex expressions in the ${} construct using the four basic operations (+,-,*,/), the unary minus, and parenthesis. -backwards compatibility script "xacro.py" in the devel/share space, points to the xacro script in source space, In install space: The xacro program runs all of the macros and outputs the result. . https://blog.csdn.net/qq_40213457/article/details/81021562 The dependencies in newer releases can't be satisfies without breaking the operating system. The reason for having two differently named scripts is that we need one with the old name, which can be found by the $(find) syntax in roslaunch files. velocity"org.apache.velocity.exception.

If the xacro with a specified name is not found, it will not be expanded and will NOT generate an error. I've modified the cmake code from @tfoote to try and reflect what @ablasdel is suggesting. In the devel space "xacro" it would exist in the scripts directory just You can also automatically generate the urdf in a launch file. The text was updated successfully, but these errors were encountered: as we do not want xacro.py to go into the global bin folder, and in CMakelists, the line.

Check out the ROS 2 Documentation. The full error message is similar to the following example: NETSDK1064: Package 'PackageName', version x.x.x was not found.

Looks like the $(find xacro)/xacro.py on launch files assumes that xacro is still a non-catkin package, and so the scripts are on share directory instead of the catkin standard (bin). I will talk to Tully and have this pushed to public ASAP. To specify a block parameter, include an asterisk before its parameter name. Backport xacro substitution args fix to fuerte? vmwareubunturosROS The two values are specified in the first two lines. :,$catkin_make:CMake Error at/opt/ros/indigo/share/catkin/cmake/safe_execute_process.cmake:11 (message): execute_process(/home/cookie/dev/catkin_ws/build/catkin_generated/env_cach ros launch This may take awhile. For example, these are the first two lines of a valid xacro file: Lets take a quick look at our base_link in R2D2. Brought up on the ros users mailing list after Tully announced new debs: I'm not sure what all the cmake-wizardry is trying to do in xacro-extras.cmake, but it appears the problem here is actually that xacro.py in /lib/xacro/ is not executable as it would be if it were brought in via a "install(PROGRAMS " type of cmake command. Maybe I wasn't being clear. Well occasionally send you account related emails.

If I execute xacro with rosrun, no problem. For this to work, i've renamed the xacro.py in source space to xacro. This is convenient because it stays up to date and doesnt use up hard drive space. , qq_42419700: Note this is also an issue for package local binary executables, those may also be both rosrunned as well as roslaunch found. GitHubhttps://github.com//issues/1#issuecomment-14416016 -velocity"org.apache.velocity.exception. privacy statement. You can also automatically generate the urdf in a launch file. This concludes this section however if you have completed all these steps you are well prepared to move into simulation. I've created a hydro-devel branch in this repo with this two script solution. Fort example, when I launch. ./ZED_SDK_Ubuntu18_cuda10.2_v3.5.0.run You can remove cached packages by executing 'dnf clean packages'. "At best the script in share should also output a deprecation warning so that packages which use that file can update to the new usage.". -backwards compatibility script "xacro.py" in share/xacro/, You can try this change by pulling from the backwards_compat branch of my fork: https://github.com/jonbinney/xacro/tree/backwards_compat Was discussing this today. . @dirk-thomas unless you think you can clean this up quickly (in particular the installing configured files).

See how we use the reflect parameter to put the legs on either side of the body in the base_to_${prefix}_leg origin. gazebo Have a question about this project? Is this bugfix in 1.7.3? A backwards compatibility script named "xacro.py" will live in /share and simply print a deprecation warning and run the "new" xacro script. The above code would be replaced with: Sure, but that is just another workaround because we lack the necessary roslaunch logic from ros/ros_comm#228. To de-xacro-ify it, copy out the contents of the 'xacro:macro' tag each time there is an instance of '<xacro:my_macro />'. After trying a bunch of things, the best fix I've found is to actually have 2 identical scripts. I can't update until this fix is in public, since xacro is important for me.

The xacro language is rather flexible in what it allows you to do. Asking for help, clarification, or responding to other answers. The executable script must be in the root of a package to be found there and after installation under lib/PKGNAME since the find command does only specify one path of the script. In my opinion, the (find ) shortcut for roslaunch files should be changed to find files the way rosrun does. This error occurs when the build tools can't find a NuGet package that's needed to build a project. Open Control Panel - Programs and Features. On ROS distros melodic and later, you should omit the {--inorder} argument. First, lets take an example of a simple macro used in R2D2.
Velocity Exception in thread "main" org.apache.velocity.exception. Sign in You can also parameterize macros so that they dont generate the same exact text every time. I found the command in a readme file in the baxter_moveit_config folder. I think I'm going to take advantage of the rollback capability. Using "rosrun xacro xacro" finds this one in both source and install. There's a lot of corner cases we need to cover. What's the progress on getting this released into Hydro? Often you want to create multiple similar looking objects in different locations. The parameters act just like properties, and you can use them in expressions. Common Trick 2: Use math to calculate joint origins. At the top, click 'Change'. It needs to be taken out of the scripts in setup.py. Usually they go at the top. I didn't have to create another dummy folder. Using $(find xacro)/xacro.py in a launchfile finds this whether working from source or an install.
