Make run_example failed

[micleb]

Hello,

I successful built Veins, Vanetza, Inet and Artery but I am stuck at : cmake --build build --target run_example

This command always failed with the following output :

The recipe for the target " run_example" failed

And I do not understand this warning message :

Attempt to load the oppsim shared library more than once. This usually happens when part of your simulation is using release libraries while other parts are using the debug version. Make sure to rebuild all parts of your model in either release or debug mode!

I just followed the tutorial step by step, that's all. What am I supposed to do/change ?

Could you help me ?

Thank you

I can see from your console dump that INET is compiled in release mode (as out/gcc-release/src/libINET.so library). As the output by opp_run tells you one should not mix OMNeT++ libraries (such as Veins, INET and Artery) when they are not all built in the same mode, i.e. release or debug.
For example, you can force INET to be built in debug mode by calling make MODE=debug in extern/inet.

I executed make MODE=debug in extern/inet. The compilation was successful.

But cmake --build build --target run_example is still not working (same output)

@riebl Any idea how to fix that ?

Like I said in my previous post, I tried make MODE=debug in the inet folder (it worked) but when I try to compile run_example the default mode is "release"

I also tried make run_example mode=debug in the build directory, but the error is still there

[riebl]

@micleb I still don't know why this problem occurs on your system. You can try to build Veins in release mode explicitly as well, similar to INET.
I have the feeling that something with the generated veins-targets.cmake and INET-targets.cmake files in your build directory is odd, e.g. one of them is missing the release configuration und thus falling back to the debug build.

[riebl]

@micleb Did you manage to get Artery running in the meantime?

Hi, I also got the same problem a while ago. I got the error on 9ec5eba and don't know if the error persists after that. However, then i tried cloning down the 655d46a commit (from march) and I didn't get the same error. So it seems to be caused by some CMake change after that. Hope it helps in discovering the issue.

[riebl]

@dnguyenkth Thanks for your additional insights. You may try to remove all *-targets.cmake files from your build directory when this problem occurs.
It seems that those files, which are generated by Artery's opp_cmake, are not updated when dependencies such as Veins or INET have been built with another mode option. Removing them forces CMake to run opp_cmake again.

[dnguyenkth]

I get it to build without any problem on the latest commit 577e2bd, so I guess this is solved now :)
