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? – Sedentary

matlab code...codegen -report kalman02.m -args {z} – Sirdar

Might be a 32/64 bit issue. What kind of system do you have? – Synectics

OK so that explains it. You need to either install 32-bit libraries, or use -m64 compiler flag. – Synectics

Answer 1

For Fedora 16 use:

sudo yum install libstdc++-static

Tav

Fixed my problem on Fedora 21. Thanks! – Pageantry

The same, worked on Ubuntu but Fedora needed the above. – Craal

Wouldn't build-essential take care of all that? – Brushwork

@Brushwork build-essential is a Ubuntu package. OP uses Fedora. – Collyrium

I also needed this in Centos 7.5 – Starfish

Running sudo dnf install libstdc++-static saved my life. Thank you. – Summersummerhouse

Answer 2

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

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

Doleful

For Ubuntu 14 try: ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib/x86_64-linux-gnu/libstdc++.so – Belated

Answer 3

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

sudo yum install libstdc++-devel.i686

Mccown

Following this website (tech.yipp.ca/compile-error/…), I found that the command: sudo yum install libstdc++-static libstdc++-static.i686 is more appropriate. Tried in my machine and worked. – Offing

Answer 4

i did sudo apt-get install g++-4.7 it work for me for matlab .

Answer 5

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

sudo yum install gcc-c++
