I am trying to install Px4-SITL GAZEBO on Ubuntu 20.04 and I get this error
Syntax error in cmake code at /home/sj/src/PX4-Autopilot/CMakeLists.txt:506
** when parsing string ${PX4 There is an unterminated variable reference.**
The syntax currently@506 is
" target_link_libraries(${PX4 Firmware} ${GAZEBO_LIBRARIES}) "
Any Ideas !!
Please paste the full output after a clean build, the full error, and the exact git commit that you’re at.
Hi …

I’m confused because from your git command it looks like you are on the main branch. However, the CMakeLists.txt there doesn’t have that many lines.
https://github.com/PX4/PX4-Autopilot/blob/82dce9353c9e17f0de23eae23d20796661441389/CMakeLists.txt
So what exactly is your git commit? Or branch?
@Hi Julian,
I used the following command after creating the " /src " folder
( git clone --recursive GitHub - PX4/PX4-SITL_gazebo-classic: Set of plugins, models and worlds to use with OSRF Gazebo Simulator in SITL and HITL. .)
Went by the guidelines dictated on GitHub - PX4/PX4-SITL_gazebo-classic: Set of plugins, models and worlds to use with OSRF Gazebo Simulator in SITL and HITL..
The above guidelines were attempted after successfully installing and running the docker version of PX4-SITL Gazebo headless using the GitHub - JonasVautherin/px4-gazebo-headless: An unofficial Ubuntu-based container building and running PX4 SITL (Software In The Loop) through gazebo. in the same "/ src " folder .
Hope this could help you in some direction to the issue…thank you …
@Julian…thank you
I was able to finally run PX4SITL Gazebo classic by installing additional GST streamer 1.0 modules using the following command
sudo apt-get install libgstreamer-plugins-base1.0-dev and then I ran the following command in PX4-Autopilot dir
make px4_sitl gazebo-classic
All the errors vanished and Gazebo started !!
I read the following link Build error GSTREAMER · Issue #13117 · PX4/PX4-Autopilot · GitHub
