Please stick with a single email thread. I believe all problems you are having stem from the same place which I mentioned at least twice now.
IRRLICHT_LIBRARY should be set to the Irrlicht library file (NOT a directory)! You are passing something like: -DIRRLICHT_LIBRARY=/opt/hamzstlib/Physics/irrlicht-1.8.5/lib/Linux In the example cmake command line I gave you (which works just fine on my machine) I set: -DIRRLICHT_LIBRARY=/usr/lib/x86_64-linux-gnu/libIrrlicht.so Please locate the library file libIrrlicht.so on your machine and set IRRLICHT_LIBRARY to be that. You are misinterpreting the output from make. 1. The library libChronoEngine_vehicle.so was built just fine. Look in the lib/ directory and you should see it there. The make command stops due to earlier errors (from trying to build Chrono Irrlicht demos because you did not set the Irrlicht library correctly). 2. The problem is not really in libChronoEngine_irrlicht.so. In fact, the library libChronoEngine_irrlicht.so is probably created and you can see it in lib/ as well. The problem is that the Irrlicht library libIrrlicht.so is not known. Note that these are shared libraries. As such, errors will occur only when you try to link an executable that uses them. Please get the above working first. Once you fix the issue above by providing the correct full path to the Irrlicht library file libIrrlicht.so in the cmake variable IRRLICHT_LIBRARY, you should be able to build Chrono with BUILD_DEMOS enabled. You will get the demo executables in the directory bin/ and can run them from within that directory. If you want to play around with the demos, you can modify their source code and then run again make at the same top-level as the first time. You should NOT try to run make in a demo subdirectory. The demo programs distributed with Chrono are just that: demos. 1. Their full source code is provided with the distribution, so I’m not quite sure why you would expect us to post the source for all of them on the documentation website. We chose to do so for a few of them (and in fact may decide to remove that from the website): indeed, that is NOT the place to get the code for a particular demo; you have that source code in the Chrono repository which you have cloned. 2. As I also mentioned a couple of times before, if you really want to experiment further with a particular demo or else want to write your own program based on the Chrono libraries, you should set up a separate project and configure that following the instructions at https://api.projectchrono.org/tutorial_install_project.html --Radu From: [email protected] <[email protected]> On Behalf Of Freya the Goddess Sent: Saturday, May 21, 2022 9:27 AM To: ProjectChrono <[email protected]> Subject: Re: [chrono] Re: ProjectChrono Compilation Error with Irrlicht Module version 1.8.5 Hi all, good day to you, I want to share the failed building / compiling with BUILD_DEMOS=ON 1. I am using Irrlicht-1.8.5 because I cannot compile Irrlicht-1.8.4 on my Linux OS system, I am able to test the Irrlicht demo on their website, all work nicely. 2. If I build Project Chrono with BUILD_DEMOS=OFF the compilation will be finished. My question is based on my screenshot there must be some problem either in libraries linking or my ccmake options? Look at 42% compiling there are warning: undefined reference to 'createDeviceEx' undefined reference to 'irr::core::IdentityMatrix' undefined reference to 'irr::video::IdentityMaterial' Is the problem located on libChronoEngine_irrlicht.so ? Then the compilation stop / failed when building libChronoEngine_vehicle.so Is the problem on my system or there are some preconfiguration needed or maybe to set environment variables for irrlicht ? Thank You Le ven. 20 mai 2022 à 17:39, Freya the Goddess <[email protected]<mailto:[email protected]>> a écrit : 1. I use the develop branch. Is it better to use version 7.0 to clone the git? 2. cmake-gui or ccmake works fine here, but I just trying using typing manually CMAKE 3. I need to fix some of the manual typed CMAKE commands. If it complicates things more I go back to ccmake, I just want to make / build Project Chrono well. Irrlicht version 1.8.5 has been tested and works, but Irrlicht-1.8.4 can't produce the library (.a or .so / static or shared), maybe that's why it has been fixed and works on version 1.8.5 by the developers. I will rebuild again with your advice, thanks Radu.
