[stunnel-users] undefined reference to `CRYPTO_set_id_callback'

Fri Nov 29 06:45:05 CET 2019

Well, OK, but why doesn't configure detect this and error out then?  I
put a lot of work into moving my system to openssl 1.1.1d since that
is supposed to be the current version.

Should I build a private, older openssl static library just for
stunnel?  I worry maybe that would miss out on bugs fixed in the
current openssl that aren't fixed in older versions.  To get everyting
else working, I wound up with this for my openssl:

CC=gcc \
./Configure linux-x86_64 \
   --prefix=/usr \
   --openssldir=/etc/ssl \
   --api=1.0.0 \
   threads \
   enable-mdc2 \
   no-asm \
   shared \
   no-ssl2 \
   no-ssl3 \
   zlib-dynamic \
   disable-fuzz-libfuzzer \
   -DOPENSSL_USE_IPV6=0 \
   -DMAKEDEPPROG=gcc

All of my other stuff works with that build of openssl.  So yeah, I
guess I'll have to build a special stunnel-only openssl.  What version
should I use, and how should I build it?  My system is a pure64 x86_64
system (no /usr/lib64, just /usr/lib) with no 32bit support at all,
and no ipv6.

I'd appreciate any hint you can give....
