I've created another patch against openssl-0.9.3 (see below) to get the
examples in the following demos directories to work ... bio, eay,
maurice, prime, sign, but not ssl which is in C++... I've got it to
compile cleanly, but it will take a bit more work to debug it... but
it's definitely a great way of learning more about OpenSSL !!!
The patch also includes a Makefile for each directory with a test:
where I can...
I am building under intel Redhat linux 5.2
Hope this is useful... should I continue to hand these "fixes" in ?
Constructive Criticism gratefully received !
cheers,
