libc.so.6 error while compiling C++ program

Question

I am a complete beginner in C++ and trying to run my first program.

#include <iostream>

int main()
{
    std::cout << "Hello world!";
    return 0;
}

Then I run, in the terminal:

g++ first.cpp

But it gives me this error:

/home/shikhar/anaconda3/bin/ld: /lib/x86_64-linux-gnu/libc.so.6: undefined reference to `_dl_exception_create@GLIBC_PRIVATE'
/home/shikhar/anaconda3/bin/ld: /lib/x86_64-linux-gnu/libc.so.6: undefined reference to `_dl_audit_symbind_alt@GLIBC_PRIVATE'

/home/shikhar/anaconda3/bin/ld: /lib/x86_64-linux-gnu/libc.so.6: undefined reference to `__tunable_get_val@GLIBC_PRIVATE'

I am using Linux Mint 21.2. \

I am unable to understand any solutions on the internet for similar errors.

Those linker errors seems odd for that simple program. How did you install the compiler and the system development files? Have you set up anything special in the terminal for development? Is perhaps g++ an alias for something else? — Some programmer dude

Try not to use binutils from conda. For example, run conda deactivate first. — Weijun Zhou

Anaconda sets some environment variables, for example $LD_LIBRARY_PATH, which interferes with the execution of your program. — Weijun Zhou

The problem was using the compiler through anaconda. Deactivating anaconda then compiling worked.

conda deactivate
