I'm following the Matlab coder kalman tutorial in Matlab help. When using codegen, there's an error as below:
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
But there is libstdc++.so.6 in /lib/ and /usr/lib
For Fedora 16 use:
sudo yum install libstdc++-static
You can soft link the library to the name that is being sought
ln -s /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so
If you're compiling a 32-bit application on a 64-bit CentOS 7:
sudo yum install libstdc++-devel.i686
i did sudo apt-get install g++-4.7 it work for me for matlab .
For CentOS, be sure you have installed gcc-c++ package (it includes libstdc++-devel dependency):
sudo yum install gcc-c++
