Do these errors say anything to you?

I have g++ 5.4.0 on Ubuntu 16.04 LTS.

Curiously, at work on a CentOS 7 machine I was able to compile it just fine.

What are the real minimum requirements for a successful build? Which versions of what?

Same Error here on ubuntu18.04 with g++ 7.4.0 :

@jlucidar If it helps you, I wrote myself this Dockerfile that can compile it successfully and consistently:

FROM centos:7
RUN yum install -y make gcc-c++-4.8.5
COPY . ./libssp/
WORKDIR ./libssp/example/linux
RUN make all && chmod 777 libssp_test
CMD ./libssp_test

(I didn't check if the resulting file works as-is in Ubuntu though.)

[jlucidar]

Yup, did the same ^^ It works directly in Ubuntu ;)

[secit]

Use g++ version 4.8.5, then it should compile just fine.
