no eigen, ceres, opengv directory

[JaimeParker]

Hi everyone, in file fix_eigen_deps.sh

#eigen_catkin
cd ${BASEDIR}/..
if [ -d "eigen_catkin" ]
then
  cd eigen_catkin
  FIX_EIGEN_VERSION="1"
  if grep -q "covins_patched" CMakeLists.txt; then
    FIX_EIGEN_VERSION="0"
  fi
#  echo "FIX_EIGEN_VERSION: $FIX_EIGEN_VERSION"
  if [ "$FIX_EIGEN_VERSION" == "1" ]
  then
    echo "set eigen_catkin to 3.3.4"
    sed -i '13d' CMakeLists.txt
    sed -i '12aset(EIGEN_MINIMUM_VERSION 3.3.4)' CMakeLists.txt
    sed -i '88d' CMakeLists.txt
    sed -i '88d' CMakeLists.txt
    sed -i '87a\ \ \ \ URL https://gitlab.com/libeigen/eigen/-/archive/3.3.4/eigen-3.3.4.tar.bz2' CMakeLists.txt
    sed -i '88a\ \ \ \ URL_MD5 6e74a04aeab3417120f1bdef6f3b4881' CMakeLists.txt
    sed -i '46aset(USE_SYSTEM_EIGEN "OFF")' CMakeLists.txt
    sed -i '1i# covins_patched' CMakeLists.txt
  else echo "eigen_catkin already set to version 3.3.4"
  fi
else echo "ERROR: no eigen_catkin directory"
fi

it means there should be a folder called eigen_catkin in covins_ws/src, but there isn't.
I have eigen3.4.0 and ceres on my ubuntu, not sure about opengv(I can run ORB_SLAM3 and 2 on my device).
Do I need to copy these files in src or is this a bug? Or did I mistakenly operate something? thanks for your reply, in advance.

Hi
The mentioned folders (besides others) are listed in the dependencies.rosinstall file and get automatically installed from the install file. So if you follow the installation guide step by step all dependencies should be installed.
Regards Thomas

Sir I'm rather confused, there is no command to download eigen, ceres and opengv in file src, so when install script pointing to fix_eigen_deps.sh, it just run down to ERROR: no eigen_catkin directory

[JaimeParker]

I just git clone all files in dependencies.rosinstall in src, with the covins file.

[JaimeParker]

fixed, need to clone all files in dependencies.rosinstall , then run that install command

[ThomasZiegler]

It's strange that you had to clone the repos manually. Normally the installation scripts takes care of that and automatically. It clones the repos via the python3-wstool. Could it be that you did not install the listed dependencies i.e. sudo apt-get install python3-wstool?

[JaimeParker]

@ThomasZiegler thank you, sir. I tested sudo apt-get install python3-wstool again, and it said that python3-wstool has been the newest version, and when I ran it before

cd ${BASEDIR}/..
wstool init
wstool merge covins/dependencies.rosinstall
wstool up

I can see info provided by wstool, just didn't know whether it's successful.
Whatever, it did show that if something went wrong, we can install these files manually, also a solution I guess.

Hi
I reproduce this problem by running
wstool merge covins/dependencies.rosinstall
, then I get
File "/usr/lib/python3/dist-packages/wstool/config_yaml.py", line 74, in get_yaml_from_uri yamldata = yaml.load(stream) TypeError: load() missing 1 required positional argument: 'Loader'
YAML does not support .load(f) after v5.1 anymore as it's considered to be unsafe. safe_load or load(f, Loader=FullLoader) is recommended.
So I just replace yaml.load with yaml.safe_load and it goes well.
