Unknown CMake command "PROTOBUF_GENERATE_CPP".

[mboisson]

I'm trying to build ign-gazebo3_3.8.0, and I encounter:

26409 CMake Error at src/msgs/CMakeLists.txt:2 (PROTOBUF_GENERATE_CPP):
26410   Unknown CMake command "PROTOBUF_GENERATE_CPP".
26411

According to this page
https://stackoverflow.com/questions/52533396/cmake-cant-find-protobuf-protobuf-generate-cpp
there would be something missing in the CMakeLists.txt, but even patching it did not resolve the issue.

I have protobuf/3.12.3 and cmake/3.16.5

Any idea ?

Below is the full log:

-- Configuring incomplete, errors occurred!

[chapulina]

I have protobuf/3.12.3 and cmake/3.16.5

I think your Protobuf version is too new. What OS are you in?

Would you mind using the issue template next time and filling the relevant info? Thanks! ✌️

[traversaro]

Probably you need to define to ON the protobuf_MODULE_COMPATIBLE CMake option in ign-gazebo. The motivation is a bit intricate, but you can find some details in the PR linked by @chapulina : #715 .

[mboisson]

My apologies. I did not use the template because none of it seemed relevant, but still, here it is :
OS Version: Gentoo on top of CentOS, using Lmod and EasyBuild to provide many pieces of the software. This is for a supercomputer.
Source version: (version provided above)
It is not a rendering error, but rather a compilation one.

What version of protobuf is needed ?

The PROTOBUF_GENERATE_CPP function does exist in our installation of protobuf. It seems that it is not about the function not existing, but rather that it is not being found:

[traversaro]

I already tried patching the relevant (I think) CMakeLists.txt files with this patch:

I am afraid that patch will not work if protobuf_MODULE_COMPATIBLE CMake cache variable is already defined by a previous (transitive) call to find_package(Protobuf CONFIG) . I suggest to move the patch earlier in the CMakeLists.txt before any find_package call, or just pass it as a CMake command line option.

[traversaro]

In a sense, probably we just need to move the line https://github.com/ignitionrobotics/ign-gazebo/blob/ign-gazebo5/CMakeLists.txt#L140 before any call to find_package (or at least any call that transitive search for Protobuf).

[mboisson]

Adding to the cmake command line options worked, so I guess I can workaround it without the patch.

Now I hit another compilation bug, which seems related to ignition-physics2:

26511 CMake Error in src/systems/physics/CMakeLists.txt:
26512   Imported target "ignition-physics2::ignition-physics2" includes
26513   non-existent path
26514
26515     "/cvmfs/soft.computecanada.ca/easybuild/software/2020/Core/eigen/3.3.7//cvmfs/soft.computecanada.ca/easybuild/software/2020/Core/eigen/3.3.7/include"
26516
26517   in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:
26518
26519   * The path was deleted, renamed, or moved to another location.
26520
26521   * An install or uninstall procedure did not complete successfully.
26522
26523   * The installation package was faulty and references files it does not
26524   provide.

I guess I should open a separate issue for this ?

The path should obviously be
/cvmfs/soft.computecanada.ca/easybuild/software/2020/Core/eigen/3.3.7/include
rather than
/cvmfs/soft.computecanada.ca/easybuild/software/2020/Core/eigen/3.3.7//cvmfs/soft.computecanada.ca/easybuild/software/2020/Core/eigen/3.3.7/include

Not sure (yet) how ignition-physics2 gets that separate path....

[mboisson]

Any pointer about how those cmake files are generated ? It obviously detect eigen and writes it in this cmake file, but writes it incorrectly.

[traversaro]

I guess the patch in gazebosim/gz-physics#282 should fix the problem (note that the PR is against ign-physics4, but I guess that probably a similar fix can be applied to ign-physics 2).

[traversaro]

See https://cmake.org/cmake/help/latest/manual/cmake-packages.7.html#creating-relocatable-packages for more details on CMake relocatable packages (that I guess it is what is required by easybuild, even if I am not an expert).

[mboisson]

We do not (usually) install in place, indeed. So I guess they need to be relocatable. Thanks for the pointer. I will try the patch (or a similar patch).

[traversaro]

Not sure what is your use case for ign-gazebo, but in that case probably you may be interested in #626 .

[mboisson]

I am just trying to build all of ignitition-citadel suite. Our user actually asked for ORSF Gazebo 11, and it depends on a lot of the ignition-citadel components, so I figured I would install all of the components, and then build ORSF Gazebo 11 using ignitition-citadel as a dependency. Is that a bad idea ? Should I skip some components ?

[mboisson]

🤔 , now the configuration passes, but the build fails...

Maybe building gazebo is not such a good idea, but if it does not build, doesn't that mean that other components were not built correctly ?

Our user actually asked for ORSF Gazebo 11, and it depends on a lot of the ignition-citadel components, so I figured I would install all of the components, and then build ORSF Gazebo 11 using ignitition-citadel as a dependency. Is that a bad idea ? Should I skip some components ?

It is not a bad idea, but probably it is more work then necessary, as for Gazebo 11 you will not need ignition-gazebo or ignition-physics, that are exactly the one that are giving you problems.

However, I guess we are definitely OT at this point here, so perhaps it could make sense to open an issue in osrf/gazebo repo instead?

Ok. I will do this.

build ORSF Gazebo 11 using ignitition-citadel as a dependency.

If it helps, instead of building the entire collection-citadel from source as instructed on our docs, you can just get the Gazebo 11 dependencies from gazebo11.yaml.
