Explanation of the error message “libstdc++.so.6: error adding symbols: dso missing from command line”
The error message “libstdc++.so.6: error adding symbols: dso missing from command line” typically occurs when you are trying to compile or link a program, and it is unable to find the necessary libraries or shared objects (“.so” files) for the libstdc++ (GNU Standard C++ Library).
Possible Causes
- Missing or incorrect installation of libstdc++ library.
- Incorrect compiler or linker flags.
- Missing or incorrect library paths.
Solution Examples
1. Using GCC Compiler
If you are using the GCC compiler, you can try the following solutions:
# If you are compiling a C++ program
g++ your_program.cpp -o your_program -lstdc++
# If you are linking against a shared object file
g++ your_program.cpp -o your_program -L/path/to/libstdc++ -lstdc++
# If you are using a Makefile, ensure you have the proper flags
LDFLAGS = -L/path/to/libstdc++
LDLIBS = -lstdc++
your_program: your_program.cpp
$(CXX) $(CXXFLAGS) $(LDFLAGS) -o $@ $^ $(LDLIBS)
2. Using Clang Compiler
If you are using the Clang compiler, the options are similar:
# If you are compiling a C++ program
clang++ your_program.cpp -o your_program -lstdc++
# If you are linking against a shared object file
clang++ your_program.cpp -o your_program -L/path/to/libstdc++ -lstdc++
# If you are using a Makefile, ensure you have the proper flags
LDFLAGS = -L/path/to/libstdc++
LDLIBS = -lstdc++
your_program: your_program.cpp
$(CXX) $(CXXFLAGS) $(LDFLAGS) -o $@ $^ $(LDLIBS)
3. Adjusting Library Paths
Alternatively, you can add the library path to the LD_LIBRARY_PATH environment variable. For example:
export LD_LIBRARY_PATH=/path/to/libstdc++:$LD_LIBRARY_PATH
Make sure to replace “/path/to/libstdc++” with the actual path where the libstdc++.so.6 library is located on your system.
By following these steps, you should be able to resolve the “libstdc++.so.6: error adding symbols: dso missing from command line” error and successfully compile or link your program.
