I have the following program:

#include <iostream>
#include <sstream>
using namespace std;

int main()
{
    //ostringstream s;
    cout << "cpp test" << endl;
    return 0;
}

I build it on Ububtu 20.04 desktop using cross-compiler:

arm-linux-gnueabihf-g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/cpp_test.d" -MT"src/cpp_test.o" -o "src/cpp_test.o" "../src/cpp_test.cpp"
arm-linux-gnueabihf-g++  -o "cpp_test"  ./src/cpp_test.o

Then I copy cpp_test to BeagleBone Black Wireless board and execute it:

debian@beaglebone:~/c$ ./cpp_test 
cpp test
debian@beaglebone:~/c$ ldd cpp_test
    linux-vdso.so.1 (0xbee85000)
    libstdc++.so.6 => /usr/lib/arm-linux-gnueabihf/libstdc++.so.6 (0xb6ea1000)
    libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0xb6e78000)
    libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0xb6d7e000)
    libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0xb6d03000)
    /lib/ld-linux-armhf.so.3 (0xb6fbe000)

Now I uncomment the line ostringstream s;, build the program, copy it to BeagleBone and execute:

debian@beaglebone:~/c$ ./cpp_test 
./cpp_test: /usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./cpp_test)

    libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0xb6c84000)

Both computers, host and BB board, are completely updated.

Not really an answer, but on my Ubuntu 20.04 system, I have package libstdc++6 installed, containing libstdc++.so.6.0.28.

Looking for symbols

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.28 | grep GLIBCXX

gives

...
GLIBCXX_3.4.19
GLIBCXX_3.4.20
GLIBCXX_3.4.21
GLIBCXX_3.4.22
GLIBCXX_3.4.23
GLIBCXX_3.4.24
GLIBCXX_3.4.25
GLIBCXX_3.4.26
GLIBCXX_3.4.27
GLIBCXX_3.4.28
...

So, it seems, version 6.0.28 corresponds to symbol 3.4.28.

In your case, you have libstdc++.so.6.0.25 installed, which is just one less than GLIBCXX_3.4.26. So, you must either upgrade the Beagle board, or downgrade the dev environment.


Current (focal, 20.04) libstdc++6 version is 6.0.28. Version 6.0.25 is contained in bionic (18.04), which also contains gcc-8.

So, maybe installing package gcc-8/g++-8 and its dependencies (e.g. libstdc++-8-dev) solves this.

GLIBCXX_3.4.26 comes with gcc-8. Installing gcc-8 and upgrading libstdc++6 worked for me. Run the following as shown here:

sudo apt update
sudo apt install wget gcc-8 unzip libssl1.0.0 software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt-get install --only-upgrade libstdc++6

You may not have Debian 11 as OS, 3.4.26 is not available for Debian 10. After upgrading to Debian 10, I could run the program without error.
