Why not also linking libunistring statically ? We build wget and it's fuzzers statically (except libc6) for oss-fuzz. This includes static builds + installs of libunistring, libidn2, libpsl, nettle and gnutls. You can view to Dockerfile and build script by git clone https://github.com/google/oss-fuzz ls -la oss.fuzz/projects/wget/ Regards, Tim
