@avikivity do we really have to (or want to) make this dependency hard? Couldn't we discover in configure.py whether we have sdt.h, and only compile the STAP stuff when it exists, or make it a do-nothing macro when it doesn't? In C++17, there is even a #if __has_include (see http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p0061r1.html).

This is really an unwanted forced dependency. Ideally, this becomes optional instead and allows people deploying this to hard disable it in production.

[avikivity]

If you don't want the dependency, send a patch to make it optional

I'm already working on making cryptopp obsolete, but now I run into this dependency.

BTW, systemtap hard requires python2.................................................................

I am spinning in circles, and, this is starting to ruin my weekend.

hmm, looks like there's a flag to configure it for py3.... well that's one problem solved.
