Thanks for opening this issue, the first error on the first translation unit it starts like

[pdell-kitware]

Ok, thanks ! So it seems that std::optional is not found. strange.

Can you try adding the line

#include <optional>

At the top of the schema.h file ? Also has the Superbuild installation worked ?

Also, can you tell me which compiler do you use ?

[nachovizzo]

So moving forward, I included the header files that were missing (I recommend checking out "include-what-you-use"). And now it did compile, but we are getting linking errors.

Compiler

I'm using gcc on ubuntu. The superbuild did work

[pdell-kitware]

Thanks I'll check this out,

Can you tell me which version of gcc do you have ? With gcc < 7.5 we had some compilation problem (because we use C++-17)

[nachovizzo]

$ gcc --version

Thanks, I'll try to replicate the bug, and I'll get back to you

[nachovizzo]

Amazing! Thanks a lot for the help!!!!

[pdell-kitware]

If you try a different compiler, it would be very helpful,

For example if you have clang on your system, before running the cmake install script, You can export the environment variables:

which clang                     # Checks the clang installation

# -- Setup environment variables
export C=clang               
export CXX=clang++

# -- CT_ICP Install
mkdir cmake-build-release && cd  cmake-build-release                  #< Create the build directory
cmake .. -DCMAKE_BUILD_TYPE=Release                                   #< (2) Configure with the desired options (specify arguments with -D<arg_name>=<arg_value>)
cmake --build . --target install --config Release --parallel 12       #< Build and Install the project

(And do delete the cmake cache before launch the new installation)

[pdell-kitware]

This should now be resolved with commit f2db6a1

[nachovizzo]

Yay! Finally it's building, now let's see how to run this on the data :)

Thanks!

[nachovizzo]

You can close the issue

[nachovizzo]

Sorry to bother again, I still can't run this code

ct_icp/install/CT_ICP/bin (master) ./run_odometry -c ../../../config/odometry/driving_config.yaml
./run_odometry: error while loading shared libraries: libglog.so.0: cannot open shared object file: No such file or directory

Which magic export I might be missing?

[nachovizzo]

Update, most libraries are missing from the binary:

libSlamCore.so
        libyaml-cpp.so.0.6 => not found
        libceres.so.2 => not found
        libtinyply.so => not found
        libglog.so.0 => not found

[pdell-kitware]

Can you run readelf -d run_odometry ? And notably look at the RUNPATH ?

Sorry to use you as an early tester 😅

[nachovizzo]

adelf -d run_odometry

I fixed the issue (setting the path to the external shared libraries in the RPATH of the executables and libraries built by the project)

The tests run on the CI (see this JOB)

So you should be good to go, but let me know if you have any more problems

@ajxdhe,

The problem is that you are compiling again in gcc 7.5 which does not support completely <filesystem>,

As can be seen in:

/usr/bin/../lib/gcc/x86_64-linux-gnu/7.5.0/../../../../include/c++/7.5.0/experimental/filesystem:47:11: note: 'std::experimental::filesystem' declared here
namespace filesystem

Your problem (in your second answer) is that you probably did not delete the CMakeCache.txt before configuring the project again.

Try deleting the cmake-build-release directory, then

export CC=clang
export CXX=clang++

mkdir cmake-build-release && cd  cmake-build-release                  #< Create the build directory
cmake .. -DCMAKE_BUILD_TYPE=Release                                   #< (2) Configure with the desired options (specify arguments with -D<arg_name>=<arg_value>), add -DWITH_VIZ3D=ON to install with the GUI
cmake --build . --target install --config Release --parallel 12       #< Build and Install the project

If you have any more issues on this topic, please write them on Issue #35

I confirm this solve the build error, now I have another errors :angel:

That's not possible, the tests pass 😛

Thanks again for all the effort, it was very helpful !

[pdell-kitware]

I'll close this for now .
