project template build failed

[AllenChienXXX]

Hi, I'm following the tutorial and decided to build the project template, but it keeps failed to build and produce a lot of errors. I followed the exact steps in the documentation.
I guess the reason it's generating so many errors is because there are multiple dependencies that are not compatible between my ros2 iron and ignition gazebo fortress?

Environment

• OS Version: Ubuntu 22.04 LTS on arm64
• Source or binary build?
  binary build, the latest version

Description

Hi, I'm following the tutorial and decided to build the project template, but it keeps failed to build and produce a lot of errors. I followed the exact steps in the documentation.
I guess the reason it's generating so many errors is because there are multiple dependencies that are not compatible between my ros2 iron and ignition gazebo fortress?

Steps to reproduce

I just follow the exact steps on the tutorial

Output

there are so many errors, I only include the most botton ones:

Same issue here with dependencies. Has this been fixed?
OS Version: Ubuntu 22.04 LTS
ROS: Humble
Gazebo: Fortress

Followed template instructions and removed/reinstalled gazebo, but there are dependencies that must not be in the default packages: for example "gz-plugin2"

[YoungRicky7]

same here, got errors when building
**CMake Error at CMakeLists.txt:13 (find_package):

I had this error before it is because you don't have required dependency on your system, you have to install gz-cmake package manually, check https://gazebosim.org/libs/cmake/

[Reka-Berci-Hajnovics]

Same issue here. I'm running a docker file (FROM osrf/ros:jazzy-desktop-full) and I'm trying to build the template project, but it fails with the following error:

--- stderr: ros_gz_example_gazebo                              
CMake Error at CMakeLists.txt:26 (find_package):

Failed   <<< ros_gz_example_gazebo [0.42s, exited with code 1]

[Reka-Berci-Hajnovics]

I have solved the above issue by commenting the following lines in the CMakeLists.txt of ros_gz_example_gazebo:

# Harmonic
#if("$ENV{GZ_VERSION}" STREQUAL "harmonic")
find_package(gz-sim8 REQUIRED)
set(GZ_SIM_VER ${gz-sim8_VERSION_MAJOR})
message(STATUS "Compiling against Gazebo Harmonic")
# Default to Garden
#else()
#  find_package(gz-sim7 REQUIRED)
#  set(GZ_SIM_VER ${gz-sim7_VERSION_MAJOR})
#  message(STATUS "Compiling against Gazebo Garden")
#endif()

Now it is not looking for gz-sim7, and it builds with gz-sim8 by default.
