Hello,
I followed the Webminar about Generating C++ code with Matlab Coder (<http://www.mathworks.com/company/events/webinars/wbnr56354.html?id=56354&p1=869881600&p2=869881618>) and i tried to replicate the easy examples in Linux.
I started with
function c = foo(a,b) %#codegen
c = a * b;
and I generate the project, but in the build process I got severals errors messages like:
Build error: Compilation returned error status code 2. See the target build log for further details.

Anyone has a clue what happened?
Thanks in advance,
Michael.

Hi, It appears that you have an incomplete install of the gcc compiler. Based on the build log, the 'gcc' command requires (for example) 'libstdc++.so', which apparently isn't installed on your machine.
Have you tried compiling the standard 'hello world' C program on your Linux system? This would be a quick check to see if you have a good install of gcc.
