Linking error in building apps.

[bchoineubility]

Hi community,

I am brandnew for mrpt2 and trying to build mrpt2 for humble edition now. by the way, I have an issue for building apps which include header file, libs/gui/include/mrpt/3rdparty/mathplot/mathplot.h.

error log tell undefined reference to mpMovableObject::~mpMovableObject().

error log is the followinng:

I have to do workarround by removing apps which include the header file in the apps/CMakeLists.txt as follows:

list(REMOVE_ITEM LIST_MRPT_APP_DIRS  2d-slam-demo RawLogViewer)

Can you please help me?

BR, Mark

[jlblancoc]

Are you using the standard way to build using cmake?

What is your OS?

Anyway, I just pushed a commit that might fix it, but it's really weird that this error never happened to us or to any of the CI builds :-) So, if you have cloned the repo, please do "git pull" for the develop branch and try again.

@jlblancoc Many thanks for the help

I will test your push and get back to you.

Thanks again. 👍

BR, Mark

[bchoineubility]

@jlblancoc , I can build all apps without issue.

Thanks.

Thanks @jlblancoc and @bchoineubility! I ran into this when building with https://github.com/ros/meta-ros. I can confirm that this fixes the issue.

The version of gcc was: gcc version 14.1.0 (GCC). There were no special compiler options in play that I could tell, I managed to reproduce it simply with:

Awesome! Thanks for the additional feedback, @robwoolley :+1: So, it seems our (and OSRF's ROS) CI has a blind spot regarding testing for Yocto... :-)

For the records: Using MRPT >= v2.13.2 should avoid the error.
