Matlab Kalman /usr/bin/ld: cannot find -lstdc++

Question

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

What command did you use to compile you code? Also, is the source code C++ or C? — Benjamin Bannier, Nov 02 '12 at 12:22
Might be a 32/64 bit issue. What kind of system do you have? — n. m. could be an AI, Nov 02 '12 at 13:02
OK so that explains it. You need to either install 32-bit libraries, or use `-m64` compiler flag. — n. m. could be an AI, Nov 02 '12 at 13:29

The same, worked on Ubuntu but Fedora needed the above. – Max Feb 21 '15 at 08:01
Wouldn't **build-essential** take care of all that? – IgorGanapolsky Nov 16 '16 at 17:56

@IgorGanapolsky `build-essential` is a Ubuntu package. OP uses Fedora. – Qsiris Oct 12 '17 at 09:45
I also needed this in Centos 7.5 – Galder Zamarreño Mar 22 '19 at 09:21
Running `sudo dnf install libstdc++-static` saved my life. Thank you. – Tomás Ferrer Aug 04 '22 at 03:42

You can soft link the library to the name that is being sought

ln -s /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so

For Ubuntu 14 try: `ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib/x86_64-linux-gnu/libstdc++.so` – Nathan Moinvaziri Nov 04 '19 at 22:30

If you're compiling a 32-bit application on a 64-bit CentOS 7:

sudo yum install libstdc++-devel.i686

Following this website (http://tech.yipp.ca/compile-error/install-libstdc-for-32-bit-on-64-bit-centos/), I found that the command: `sudo yum install libstdc++-static libstdc++-static.i686` is more appropriate. Tried in my machine and worked. – rph Apr 12 '17 at 06:15

For CentOS, be sure you have installed gcc-c++ package (it includes libstdc++-devel dependency):

sudo yum install gcc-c++
