when ever i try to run any simulink model in external mode with my Arduino Uno i get the following error im runiung Matlab 2017a on Ubuntu 17.04.

在 MATLAB Online 中打开

Same with R2017b on Linux and Raspberry Pi.

Quick fix. Comment out line 180 of matlabroot/toolbox/coder/simulinkcoder_core/+coder/+oneclick/TargetHook.m:

% warningLog = matlab.internal.diagnostic.log.load(logfile);

And add this line below it:

warningLog.identifier = '';

I found out that this problem happens when I force MATLAB to use system libstdc++ instead of that shipped with MATLAB. In this case, the "matlab.internal.diagnostic.log.load(logfile)" line throws the error "basic_ios::clear: iostream error".

Unfortunately, I can't use MATLAB's shipping libstdc++ because it breaks more MATLAB functionality than it actually fixes.
