Cmake error when building GymFC about gymfc HOT 7 CLOSED

Hey @xabierolaz Can you provide output as text and not a screenshot? Its difficult to read and cannot be searched.
It doesn't look like Gazebo was installed correctly. If you look in that CMakeLists.txt file its trying to find the gazebo package which it can't.

Look at the value of your LD_LIBRARY_PATH environment variable and others, did you complete these steps?

CMake Error at CMakeLists.txt:4 (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.

from gymfc.

Before you execute build_plugin.sh what is the output of,
echo $LD_LIBRARY_PATH
What is the output of,
ls <install_path>/lib

from gymfc.

echo $LD_LIBRARY_PATH
outputs nothing:
xabi@xabi-VirtualBox:~/.local/share/Trash/files/gazebo/build$ echo $LD_LIBRARY_PATH

and
ls <install_path>/lib outputs:
bash: install_path: No such file or directory

so I went to a previous snapshot when gazebo was just installed, confirmed same output was still happening when entering both echo $LD_LIBRARY_PATH and ls <install_path>/lib,
so tried to do those extra steps for Local Install:

echo "export LD_LIBRARY_PATH=<install_path>/lib:$LD_LIBRARY_PATH" >> ~/.bashrc
echo "export PATH=<install_path>/bin:$PATH" >> ~/.bashrc
echo "export PKG_CONFIG_PATH=<install_path>/lib/pkgconfig:$PKG_CONFIG_PATH" >> ~/.bashrc

install_path is /home/$USER/local ../
However, when
source ~/.bashrc
I got
bash: install_path: No such file or directory, same output as when ls <install_path>/lib

Im assuming /usr/local/lib is not in load path, so I run

echo '/usr/local/lib' | sudo tee /etc/ld.so.conf.d/gazebo.conf
sudo ldconfig

but still get this error when running gazebo:

xabi@xabi-VirtualBox:~/.local/share/Trash/files/gazebo/build$ gazebo

Command 'gazebo' not found, but can be installed with:

sudo apt install gazebo9

from gymfc.

Yea something is definitely wrong with your install.

Your replacing <install_path> with your actual install path right? Your output after sourcing it not making it seem that way.

Also it's very odd to place the build in a Trash directory.

from gymfc.

It's also not clear above why your doing multiple gazebo installs, i.e., line 32 and 98. I recommend starting from stratch and following the Gazebo install from source guide.

from gymfc.

Got it working! @wil3

Clean install, checked the install path wasn't right

Now, as the last step in the guide,

I'm confirming SetupFile in gymfc.ini is pointing to the correct location, so I open gymfc.ini and:

# Configuration for GymFC
#
# In most cases this should not be modified
[DEFAULT]

SetupFile = /usr/share/gazebo-9/setup.sh


World = attitude.world
Hostname = localhost

#a random port will be sampled from the supplied range.
# This is helpful when running multiple in parellel and it takes time to 
# tear down an old connection.
GazeboNetworkPortRangeBegin = 11345
GazeboNetworkPortRangeEnd = 12345

FCPluginPortRangeBegin = 9005
FCPluginPortRangeEnd = 10005

Im guessing it should be pointing to gazebo 10 now, with its new location, is it right?, so
SetupFile =/home/$USER/local/share/gazebo-10/setup.sh

from gymfc.
