[lttng-dev] lttng ubuntu .deb packages - compilation error

[Alexandre Montplaisir]

Hi,

Did you install the "liblttng-ust-dev" package? That one is required if
you want to compile applications against UST.

sdt.h comes from "systemtap-sdt-dev", which liblttng-ust-dev depends on,
so it should get pulled in automatically once you install the dev package.

That's expected, because the SDT integration is not enabled by default.
You have to pass --with-sdt to configure to enable it. Which we do in
the Debian/Ubuntu packages, since the sdt.h header is easily available.
