[Discourse.ros.org] [Next Generation ROS] Ament Build -test failed

Thilo Zimmermann via ros-users


Hello,

I am migrating to my new workstation. I ran previously r2b3. This is the first time i was installing ardent apalone.

While i was running `src/ament/ament_tools/scripts/ament.py test --skip-build --skip-install` I got this at the end for output.

I have built the workspace before this and also ran `src/ament/ament_tools/scripts/ament.py test` earlier to this which ended with ros1_bridge failure. Is this error specific to RMW implementation. It certainly looks for the metaconfig.xml files. I haven't encountered this in r2b2 and r2b3. Kindly guide.

The failure of the test with `rmw_opensplice_cpp` is something we are also having on our CI system (see http://ci.ros2.org/view/packaging/job/packaging_linux/902/). While the bridge itself work with OpenSplice the test is currently not working correctly. We haven't had a chance to look at the test failure - it might be related to the warnings printed by Opensplice related to the `metaconfig` file as you mentioned.

The test with FastRTPS is expected to pass though. At least it does so on our CI as well as on the developer machines when we tested the recent release. Maybe you can post more information why the test failed in your case.

Hi @dirk-thomas,

I am doing a clean install in my new workstation. So I cannot really figure out any extra information. Just followed the wiki for insalling the AA release.

Using Ubuntu 16.04, I have Kinetic running from ROS1.
Do I need to install FastRTPS separately to have the test passed?

[/quote]

If you follow the [from-source instructions](https://github.com/ros2/ros2/wiki/Linux-Development-Setup) your workspace will contains the FastRTPS repository and if that passed to build it also found all dependencies. There is nothing else you need to make the tests pass.

Yes I have done accordingly. In r2b3 I did not encounter this issue with FastRTPS. Dont know why is it happening now. @dirk-thomas

@arunava_nag Do you have every test with fastrtps failing or only the bridge?
Do the simple demos work with fastrtps ? e.g.:
`ros2 run demo_nodes_cpp talker`

Tip: if you want to see the summary of all the tests you ran you can call
`ament test_results <path to your build folder>`

@marguedas

Hi I did run : `ros2 run demo_nodes_cpp_native talker`  which i believe is using fastrtps and the output is as below:

    [INFO] [talker_native]: eprosima::fastrtps::Participant * 33898080
    [INFO] [talker_native]: eprosima::fastrtps::Publisher * 42375136
    [INFO] [talker_native]: Publishing: 'Hello World: 1'
    [INFO] [talker_native]: Publishing: 'Hello World: 2'
    [INFO] [talker_native]: Publishing: 'Hello World: 3'
    [INFO] [talker_native]: Publishing: 'Hello World: 4'
    [INFO] [talker_native]: Publishing: 'Hello World: 5'
    [INFO] [talker_native]: Publishing: 'Hello World: 6'

I am attaching the log for the test_results ( sorry had to make it a .pdf to support the website format: <a class="attachment" href="/uploads/ros/original/2X/b/bed9bdb319b2d9cea3c8ceb18e643e73f3c55de8.pdf">test_results.pdf</a> (37.7 KB)

I see it failing for the fastrtps examples too on running `ament build test_results <path_to_my_build_folder>`

According to the test results pretty much every pub / sub is failing for you for both rmw impl. That is certainly not supposed to happen and something severe seems to be wrong on your system.

Can you please try to run the tests for a single package (e.g. `demo_nodes_cpp`) and check the output for why those fail. I expect a generic error in the invocation of the tests since the `talker` seems to work just fine for you.

The test result summary only tells us that the test failed (which we knew from the previous output). In order to provide more information please look at the actual test output when *running* the test.

The error message says:

I assume you are using an older version of `pytest` since this command line argument was only added in version [3.2.0](https://docs.pytest.org/en/latest/changelog.html#pytest-3-2-0-2017-07-30).

Please check that you have followed the [instructions](https://github.com/ros2/ros2/wiki/Linux-Development-Setup#how-to-setup-the-development-environment) which mention to install the latest version via pip.

Sorry, I used the binaries from

> https://github.com/ros2/ros2/wiki/Linux-Install-Debians

to get ROS 2. But even if I run the commands from the Building from Source page, the failures still occur. Even worse, when I run pytest on /ros2_ws I get a ton load of errors. All the while, the other tutorials are all working until now. Does the error come from the binary installation?

The binary instructions are only sufficient to install the Debian packages and "use" what is coming with it.

If you want to build and test your own packages you need to follow the `Linux-Development-Setup`.

You likely already had `pytest` installed from a Debian package but unfortunately the latest Debian package version is still not new enough.

[quote="paulrusu, post:13, topic:3398"]
Even worse, when I run pytest on /ros2_ws I get a ton load of errors.
[/quote]

You are not supposed to run `pytest` on the workspace `/ros2_ws`. You should use `ament test` for this instead. The build tool makes sure to invoke the test on each package separately with various command line options as well as an environment which includes all dependencies of a specific package.

Has any one come across this during building the src.

` src/ament/ament_tools/scripts/ament.py build --build-tests --symlink-install`

Your error is different than what is discussed in this thread. Therefore I suggest in the future create a new thread or a question on answers.ros.org.

Regarding the error message: it looks like you are mixing a newer version of `rmw_fastrtps_cpp` with an older version of `rmw`. This is not supported. Either stick two both packages from e.g. the latest release or use both packages from the current default branch.

i thought we are posting ros2 issues in ros discourse. And also, as this topic is related to ament build tests which i created earlier so I linked this issue to this thread.

I did `sudo apt-get remove ros-ardent-*` and also removed my workspace and then downloaded and reinstalled everything back. How do I solve this again? I think old versions Screenshot from 2018-02-02 11-22-19have stayed in. Please help, it has stopped all my development in ros2 now.

I have these installed : ![image|690x31](upload://kIgNVlHa4Agkioyzl8wl6L6bm89.png)

I resolved this by removing the opensplice_cmake_module from /opt path. The `AMENT_CURRENT_PREFIX` was messing up a lot, otherwise. Don't know though if that is the right way to do it.

[quote="arunava_nag, post:17, topic:3398"]
Warning: OSPL_URI was already set to [[file:///home/rosi/ros2_ws/install/share/opensplice_cmake_module/config/ros_ospl.xml]]. This will not override it to the default [[file:///opt/ros/ardent/share/opensplice_cmake_module/config/ros_ospl.xml]]. Please make sure this is the config that you want.

Still struggling with this though:

Ok I believe I have figured it out. Since been using the beta version and now moved to the ardent debian version.

After installation, when I moved to the ament tutorial:

    wget https://raw.githubusercontent.com/ros2/ros2/master/ros2.repos
    vcs import ~/ros2_ws/src < ros2.repos

I ran those again. That is why it was creating duplicate probably. Just realised it is clearly mentioned there:


_To start off we need to setup an underlay **without any of ROS2 installed**._

My apologies @dirk-thomas and that is great that I don't need to go through the 2 hours of build and test time to set up my ros2.
