Bug of "make px4_sitl gazebo"

[Miranda-Tian]

The version of my gazebo is 7.16.0.
First I source ubuntu_sim_common_deps.sh. Then I ran make px4_sitl gazebo.
Describe the bug
The bug shown in terminal is in the following:

-- Configuring incomplete, errors occurred!

And the content of CMakeError.log is below:

It seems that there're some problems in 'pthread_create'. But I have no idea how to fix it.
Can someone tell me how to fix that? Thanks!

Can you try make clean and then paste the output of git status and make px4_sitl?

[Mavrikant]

I'm using make px4_sitl_default gazebo and it works. But I'm not sure is it correct mentod.

[Tarrandurham]

I'm having the same issue. Tried everything, reininstalled everything, buddy's system shows the same error. make clean, git status, make px_sitl - all done.

Same thing in there, when i run "no_sim=1 make px4_sitl_default gazebo" there is the following error:

I just tested this off latest firmware environment set up as described in our docs. This is Gazebo 9 on Ubuntu 18.04. For me NO_SIM=1 make px4_sitl_default gazebo works fine.

I am closing this as the follow on posts are different reported errors as the original one.

@piradata Can you please try again with recent firmware and if you still have the problem report a new bug with detail on your environment setup. Perhaps create a gist with your full build log and link to it?

[piradata]

okay, I will test it soon, now I am using the old version of px4 on my pc, will format the laptop for a clean install Em dom, 2 de fev de 2020 19:21, Hamish Willee <[email protected]> escreveu:

Had the same issues and re-downloaded gazebo plug-ins
sudo apt-get install libprotobuf-dev libprotoc-dev protobuf-compiler libeigen3-dev libxml2-utils python-rospkg python-jinja2
sudo apt-get install libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-bad gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly -y

and it worked like a charm

[Babyboomu]

Had the same issue but it still can't run in the correct way.
