DirectFB is written in C++, but can be linked to by a C library or
program.
When doing shared link, this is fine because the linker gets help from
the DT_NEEDED flags and knows what libraries to pull in during the link.
However, during a static link, the linker does not get such help.
Properly fixing this would require that there is support in pkg-config
and autotools to specify that the C++ runtime must be linked. Alas there
is no sush support. The only option is to add -lstdc++ to the
Libs.Private field in directfb.pc. But this is not upstreamable, because
there are other C++ runtimes in the wild (e.g. -lc++ from llvm/clang).
However, DirectFB in a static scenario is probably not a very common
scenario.
Disable DirectFB for static builds.

DirectFB (Direct Frame Buffer) is a set of graphics APIs implemented
|
|
on top of the Linux Frame Buffer (fbdev) abstraction layer. It is an
|
|
alternative to X11 with a smaller memory footprint that still has an
|
|
integrated windowing system. As of 4 October 2015, DirectFB's website
|
|
http://www.directfb.org/ is down. See alternative site listed below.
