9 months ago i have solved it。 If you're using ROS 2 Humble and cannot find the libignition-math7-dev package via apt-get, it might indicate that your package sources list does not include the necessary libraries, or the library is not available in the official repositories for your current version of Ubuntu.
For ROS 2 Humble, it relies on a range of Ignition (now referred to as Gazebo Fortress) libraries, but some specific library versions might not be directly included in the software sources of all Ubuntu distributions. There are several methods to address this issue:
1. Add the Official Gazebo Repository
If you haven't already added the official Gazebo repository, you can follow these steps to do so. This ensures you can install the required Ignition (Gazebo) libraries.
First, add the Gazebo repository key:
sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
wget https://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
Then, update your package sources and try installing again:
sudo apt-get update
sudo apt-get install libignition-math7-dev
terminal ERROR: --- stderr: ros_gz_sim
CMake Error at CMakeLists.txt:22 (find_package): By not providing "Findgz-math7.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "gz-math7", but CMake did not find one.
Could not find a package configuration file provided by "gz-math7" with any of the following names:
Add the installation prefix of "gz-math7" to CMAKE_PREFIX_PATH or set "gz-math7_DIR" to a directory containing one of the above files. If "gz-math7" provides a separate development package or SDK, be sure it has been installed.
