px4 cmake error with gazebo

cs147 commented 8 years ago

ubuntu 14.04 // gazebo 7.3.1

I downloaded gazebo7 as specified here: http://gazebosim.org/tutorials?tut=ros_wrapper_versions#Gazebo7.xseries

but then when I try to do make posix_sitl_default gazebo

I get this error:

[  1%] [  2%] CMake Error at CMakeLists.txt:23 (find_package):
  By not providing "Findgazebo.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "gazebo", but
  CMake did not find one.

  Could not find a package configuration file provided by "gazebo" with any
  of the following names:

    gazeboConfig.cmake
    gazebo-config.cmake

  Add the installation prefix of "gazebo" to CMAKE_PREFIX_PATH or set
  "gazebo_DIR" to a directory containing one of the above files.  If "gazebo"
  provides a separate development package or SDK, be sure it has been
  installed.

We're not aware that our install instructions wouldn't work. I can re-check later on my machine.

Installing libgazebo7-dev fixed the problem for me. I also needed to install libopencv-dev and protobuf-compiler to be able to build the simulation.

Thanks @antoinealb for the comment. protobuf-compiler and libopencv-dev are already in the list of packages that need to be installed, and I've added a comment that libgazebo7-dev is needed in https://github.com/PX4/Devguide/pull/44.

FYI, I report the same error during a ROS package is built. After libgazebo9-dev installed by sudo apt install libgazebo9-dev command, it disappeared.
