Subject: RE: Any flags needed to statically link openmp in Linux


So, it looks like the opm des 7 patch needs to be fixed, maybe I'll do that
soon, if the creator does not.

IIRC, simple -static worked for me.  I have 1.7.6-omp-des-4 and
1.7.6-omp-des-7 static binaries that I built on Owl with gcc 4.5.0 a
year ago, and I tested these on a variety of systems (other Owl systems,
CentOS 5, maybe others) - all worked fine.

It seems I was lucky.

Sure. ;-)

Some of the reasons given there are why for the GUI we'll likely have to
use hybrid linking - static for some libs (Qt?), dynamic for others
(glibc?)  JtR Pro for Linux is linked against a purposefully old version
of glibc dynamically (so it works with newer versions as well due to
symbol versioning, but does not strictly require those newer versions),
but with OpenSSL statically.
