When I run ldd -r binary_file I get something like this:
libstdc++.so.6 => /usr/lib32/libstdc++.so.6 (0xf6d7a000)
and this seems ok.
However, I don't know what this line means, do I have the library or not and where is it:
linux-gate.so.1 => (0xf7713000)
linux-gate.so.1 is a "a virtual DSO, a shared object exposed by the kernel at a fixed address in every process' memory"
Have a look at https://stackoverflow.com/questions/19981862/what-are-ld-linux-so-2-and-linux-gate-so-1
Missing libraries are more commonly reported as not found in ldd output if I remember correctly
