commit c618c4f27986825df2026fb22b8ee222edd1afa1 Author: David Goulet dgoulet@torproject.org Date: Wed Nov 18 11:24:38 2020 -0500
configure: Fix the --enable-static-tor switch
The "-static" compile flag was set globally which means that all autoconf test were attempting to be built statically and lead to failures of detecting OpenSSL libraries and others.
This commit adds this flag only to the "tor" binary build.
There is also a fix on where to find libevent.a since it is using libtool, it is in .libs/.
At this commit, there are still warnings being emitted that informs the user that the built binary must still be linked dynamically with glibc.
Fixes #40111
