I have tried to compile fossil version a9027e7d (20th Nov 2019) with the following configure arguments on Zorin Linux 15:

./configure --static --disable-fusefs --with-th1-docs --with-th1-hooks --with-openssl=/usr/lib/x86_64-linux-gnu

This fails. The config.log file is included below. The libcrypto.a, libcrypt.a, and libc.a libraries are in the directory /usr/lib/x86_64-linux-gnu long with their dynamic .so counterparts. When I omit the --static flag, the compile against the dynamic libraries is successful. The same is true for the release version 2.10 (the dynamic compile works and the static compile fails. Can someone tell me whether some other required libraries are missing or whether for the static compilation it is necessary to compile against a specific version of libc library. There is no guidance on this in the documentation.

config.log:
