Hi,
I have installed and built chrono-8.0.0 on Ubuntu 18.04. I can run all the demos OK.

I am trying to create a new project, using tutorials ( https://github.com/projectchrono/chrono-tutorial/tree/8.0.0 ), and the template_project folder that comes with chrono (https://api.projectchrono.org/tutorial_install_project.html). When I try to configure the cmake, for these projects, I get errors for "PREPEND" subcommand not recognized. I am aware that these commands were added to cmake in only the later versions, and not in 3.10. I wonder if I am doing something wrong, or am supposed to run another template project/ tutorial versions?

Config:
gcc 7.5.0
cmake 3.10.2
irrlicht 1.8.4

CMAKE configuration Output for the tutorials case (I get same PREPEND unrecognized error for the template_project  too that came with the /chrono directory)

Hi Prakhar,
we just changed the template project and the relative chrono-config file so we surely need some feedback. 

Could you update CMake to latest version?

Yes, that fixed the error with cmake 3.27.7. I was just thrown off, because the cmake minimum version in the cmake files for all chrono was 3.10, and it does the job too. I did not expect tutorials to be requiring a different version.

Thanks for the help!
Cheers,
Prakhar

Hi Prakhar,

 

Thanks for pointing this out. We missed it in the 8.0 release but will make sure to update the template project in the latest development code so that it requires a proper CMake version, compatible with Chrono itself.

 

On a different note, like Dario also suggested, I encourage you to start using the latest code in the ‘main’ branch of the Chrono git repository. There have been many enhancements, new features, and bug fixes since the 8.0 release.

Radu,
Thanks for the suggestion - I will switch over to the main branch.

Radu,
I am building the main branch now - with the MATLAB module.

This leads to following error during make:

----------------------------------------------------------------

In file included from /home/cralab/chrono/chrono/src/chrono_matlab/ChMatlabEngine.cpp:15:0:
/home/cralab/chrono/chrono/src/chrono_matlab/ChMatlabEngine.h:85:10: error: extra qualification ‘chrono::ChMatlabEngine::’ on member ‘GetString’ [-fpermissive]
     bool ChMatlabEngine::GetString(std::string& str, std::string varname);
          ^~~~~~~~~~~~~~
src/chrono_matlab/CMakeFiles/ChronoEngine_matlab.dir/build.make:75: recipe for target 'src/chrono_matlab/CMakeFiles/ChronoEngine_matlab.dir/ChMatlabEngine.cpp.o' failed

---------------------------------------------------------------

I removed the extra namespace qualification and it works. If you agree with this fix, I can create an issue on github and create a pull request.

Hi Prakhar,

 

Thanks for the heads up. You are correct, this isa bug (most likely a copy and paste).

I’ll push the fix soon.

Radu,
Going back to building projects that use chrono - Are the tutorials from the main branch (https://github.com/projectchrono/chrono-tutorial/tree/main) supposed to build in the current commit?
I cannot build the template projects or the tutorial projects for the main branch. This is after I can successfully run the demos.

I am attaching the log from the make process.

Hi Prakhar,

Yes, the chrono-tutorial project, as well as the template project in the Chrono repository are supposed to work (assuming you have pulled the latest code in both repos).

Having said that, Dario and I worked in this part of the code recently, with some significant changes and so it's possible we introduced a bug. I don't see any issues on my windows box.

Could you please send us your cmake cache file and the output from cmake when configuring chrono-tutorial?

Thanks, I think I need to make a run on a Linux machine. I didn't have the chance yet

Prakhar,

 

Dario and I worked out a fix for the issue you reported with the Chrono project configuration script.

I tested this with the chrono-tutorial projects, on both Windows and Linux. 

Please pull the latest code and let us know if this resolves your issue.  Note that I also pushed the fix to the ChMatlabEngine.h header.

Thanks Radu, Dario,
I am able to build the projects now.
