An error occurs when generating a custom message using rosgenmsg.

An error occurs when generating a custom message using rosgenmsg.

The error is as follows.

ThemeCopy

>> rosgenmsg('/root/mavros_msgs/')
Identifying message files in folder '/root/mavros_msgs'..Done.
Validating message files in folder '/root/mavros_msgs'..Done.
[0/1] Generating MATLAB interfaces for custom message packages... 0%Error using ros.internal.utilities.getCMakeBinaryPath (line 24)
    Could not find CMake in your system. Please install CMake version 3.15.5 or higher and rerun the command.

Error in rosgenmsg (line 223)
builder = ros.internal.CatkinBuilder(genDir, pkgInfos{iPkg});

However, I have already installed cmake 3.20.5.

However, matlab does not seem to recognize the cmake installed on the desktop.

ThemeCopy

>> !which cmake
/usr/local/bin/cmake
>> !cmake version
cmake: /usr/local/MATLAB/R2020b/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by cmake)

The above error occurs when checking the cmake version in the matlab command window.

Can you help me?

I run matlab in docker, ubuntu 20.04, cmake 3.20.5, python2.7 environment.

and matlab version is 2020b

The solutions on answer thread have already been implemented. But that didn't solve my problem.

All I can do is try a different version of Matlab.

I saw the answer that using 2021b did not cause any problems related to cmake.

You can also contact Technical Support. They should be able to help better with knowledge of your specific system, what you have tried, and actively troubleshooting with you.

thank you. However, when I changed it to 2021b version, the problem was solved.
