ROS2 compile a standalone node: undefined references to `std::__throw_bad_array_new_length()'
显示 更早的评论
Hi all,
I am trying to create a standalone node for ROS2 with a publisher (see schema below) and I am using the following tutorial to set up the model to generate the code:
but when I compile it, I obtain the following error
undefined reference to `std::__throw_bad_array_new_length()
and I don't find a way to fix (below the imag with the error). I also got the same error with the Simulink model used in the tutorial.
System info:
- OS: Ubuntu 22.04 LTS
- ROS2 version: Humble
- gcc version: 11.4.0

Hi Federico,
Thanks for providing the system information. This error seems to be a compiler incompatible issue.
In R2023b version of MATLAB/Simulink, some internal packages were built with gcc-10. Hence, when compiling the Simulink model with gcc-11, you may see undefined reference errors.
This issue was resolved in the upcoming R2024b version, which uses gcc-12 to build those packages.
As a workaround for R2023b, you could consider installing gcc-10 on your machine so that the entire project uses the same gcc version during build process.
Best,
Josh

Hi Josh Chen,
you were right, I changed the version of gcc on my system and I resolved the problem.
I leave here the small resume of how to change the version of gcc/g++ on Ubuntu 22.04 LTS:
# Install gcc-10 and g++--10
sudo apt install gcc-10
sudo apt install g++-10
# Remove all alternatives configuration
sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
# Add alternatives configuration for gcc/g++ versions
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-11 11
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-11 11
# Change the default gcc/g++ version
sudo update-alternatives --config gcc
sudo update-alternatives --config g++
# Check the gcc verion
gcc --version
# Add gCC/g++ configuration for colcon
echo "export CC=/usr/bin/gcc-10" >> ~/.bashrc
echo "export CXX=/usr/bin/g++-10" >> ~/.bashrc
source ~/.bashrc
#run matlab/simulink
and in simulink I went to ROS tab, I opened Hardware settings>code generation and in the label Language standard inside the Target selection I choose C++10 (ISO):

hi, thank you very much for your guide but i couldn't choose C++10(ISO) on the Language Standard bar
i can only see C++03 AND C++11
how to change it to C++10???!
[later]
Hi Josh, do you have any idea what should i do?!
