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.
