Compiling with -static-libgcc -static-libstdc++ still results in dynamic dependency on libc.so

by

GNU libc is not designed to be statically linked. Important functions, e.g. gethostbyname and iconv, will malfunction or not work at all in a static binary. Arguably even worse, under some conditions a static binary will attempt to dynamically open and use libc.so.6, even though the whole point of static linkage is to avoid such dependencies.

You should compile your program against uClibc or musl libc instead.

(This has been true for at least 15 years.)
