Build Issue (PCL version error) about lidarslam_ros2 HOT 13 CLOSED

Hey again, I noticed you labeled the foxy branch as failing. I managed to get it to build.
-First I changed the C++ version from 14 to 17 which resolved a bunch of errors related to the compiler.
-Second I changed the following namespaces form g2o to std (but I don't think that's a valid solution) at line 269 to 276:

g2o::SparseOptimizer optimizer;
optimizer.setVerbose(false);
std::unique_ptrg2o::BlockSolver_6_3::LinearSolverType linear_solver =
// g2o::make_unique<g2o::LinearSolverEigeng2o::BlockSolver_6_3::PoseMatrixType>();
std::make_unique<g2o::LinearSolverEigeng2o::BlockSolver_6_3::PoseMatrixType>();
g2o::OptimizationAlgorithmLevenberg * solver = new g2o::OptimizationAlgorithmLevenberg(
// g2o::make_uniqueg2o::BlockSolver_6_3(std::move(linear_solver)));
std::make_uniqueg2o::BlockSolver_6_3(std::move(linear_solver)));

from lidarslam_ros2.

Did you use the humble branch? Please use the foxy branch.
https://github.com/rsasaki0109/lidarslam_ros2/tree/foxy

from lidarslam_ros2.

When I git clone, I am obligated to use the the general branch correct?
So I have to run git clone --recursive https://github.com/rsasaki0109/lidarslam_ros2 and then run cd lidarslam_ros2 && git checkout foxy followed by building the project from the workspace directory using colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release

from lidarslam_ros2.

With that, the humble branch's submodule will be used.
Please use the following command.

git clone --recursive https://github.com/rsasaki0109/lidarslam_ros2 -b foxy

from lidarslam_ros2.

I ran the git clone command provided and then built the workspace like instructed and I got a really long error for a build failure.
Here are some snipets (since the error message can't be fully read in terminal):

How about deleting the 'install' and 'build' from the workspace and then building it again?

from lidarslam_ros2.

Do you have a different version of PCL installed than the default one in ROS2 Foxy? If so, you might need to uninstall it.

from lidarslam_ros2.

What is the version I need specifically?
When I run locate PCLConfig.cmake I get multiple versions like so:

I haven't used ros2 foxy for a while, so I forgot the pcl version.

from lidarslam_ros2.

Perhaps 1.10.

from lidarslam_ros2.

I ended up running the locale pcl and looking through any possible versions and found out I have pcl-1.10 and pcl-1.12 installed as well as the pcl debian package. I ended up calling sudo rm -r on the paths to these location leaving only the pcl debian package which made the error no longer pop up.
I am now getting a g2o related error with this following erro log, do you have any idea why:

It seems that the issue has been resolved, so I am closing it.
