SNP TPP Build Error

[marip8]

          I'm not sure if this is the right place for this. I tried running changes from this PR locally on my machine. I was able to compile fine, but when I run `ros2 launch snp_automate_2022 start.launch.xml`, the `snp_tpp_app` fails -

[snp_tpp_app-6] /home/srsidd//ws/install/snp_tpp/lib/snp_tpp/snp_tpp_app: symbol lookup error: /home/srsidd/ws/install/noether_gui/lib/libnoether_gui.so: undefined symbol: _ZNK4YAML4Node2asIiEET_v
[ERROR] [snp_tpp_app-6]: process has died [pid 43187, exit code 127, cmd '/home/srsidd/ws/install/snp_tpp/lib/snp_tpp/snp_tpp_app --ros-args --params-file /tmp/launch_params_kchfuebp'].

Not sure why. I tried doing some digging and it turns out if I comment out loading the mesh modifier (L93 on noether_gui/src/tpp_pipeline_widget - mesh_modifier_loader_widget_->configure(config[MESH_MODIFIERS_KEY]); and tool path modifier (L110 on noether_gui/src/tpp_pipeline_widget - tool_path_modifier_loader_widget_->configure(config[TOOL_PATH_MODIFIERS_KEY]); then the app runs fine without crashing. I checked and the header files are all included.

If it's better, I can open a separate issue, but considering it's part of this PR I thought I'd drop a comment here. Any thoughts? Have you run into this issue as well?

This issue should be addressed by #37. Are you using a version of scan-n-plan workshop that includes these changes? Also, you'll need to update your version of the noether repository to the hash listed in the dependencies.repos file. There is a corresponding update to noether that is captured in that hash

I'm using this fork and branch that @marrts created for Humble. I did a meld to compare the two forks, and most of the changes in the fork I'm using are small fixes (Use .hpp instead of .h, use std instead of boost etc.). I don't see anything that can cause a linking error with yaml-cpp. Do you know what specific changes are in that hash that I can port over which I can fix?

I have the other changes to include the correct yaml-cpp header files.

AFAIK the port to the latest version of tesseract is totally independent of the snp_tpp package, so you should be able to rebase that branch onto the latest master branch (if it isn't already), pull the specified version of noether, rebuild and test.

[srsidd]

Rebasing onto latest master and checking out the specific version didn't fix the error unfortunately.

However, after some more testing, I found something strange. When I compile my workspace in "Debug" mode (Specifying cmake arguments with colcon) the app does not crash, but when I compile in Release or RelWithDebInfo or Release the application crashes.
