Thanks for all the replies. I haven't got quoting right in gmail. Nathan Hartman I used git clone git://git.openssl.org/openssl.git ., so I guess I am using the latest development version. I will see if I can use a tagged version.
Daniel Shahaf I will try Nathan Hartman's suggestion of using a tagged release of openssl. If that doesn't work, I will try asking on the serf mailing list Nico Kadel-Garcia Sorry, I forgot to add my operating system. It is Devuan Ascii. uname -a gives Linux jrlp02 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u5 (2019-08-11) x86_64 GNU/Linux Andreas Stieger I want to be able to run PVS-Studio source code analyzer on the code, but want to make sure I have a buildable version first.
