Q2 - build demo error

[Philip Rhoades]

People,

Using Fedora 25 x86_64 I get:

Program drivers/framebuffer/spec/sdl/fb_sdl
COMPILE fb_sdl.o
COMPILE input.o
LINK fb_sdl
/usr/bin/ld: cannot find -lsupc++
collect2: error: ld returned 1 exit status
/root/genode/repos/base/mk/prg.mk:174: recipe for target 'fb_sdl' failed
make[3]: *** [fb_sdl] Error 1
var/libdeps:375: recipe for target 'fb_sdl.prg' failed
make[2]: *** [fb_sdl.prg] Error 2
Makefile:270: recipe for target 'gen_deps_and_build_targets' failed
make[1]: *** [gen_deps_and_build_targets] Error 2
make[1]: Leaving directory '/root/genode/build.lx'
Error: Genode build failed
Makefile:307: recipe for target 'run/demo' failed
make: *** [run/demo] Error 252

The only relevant Google result taslked about static linking . . but I
thought it better to ask here first . .

Thanks,

Phil.

your host system misses a proper C++ compiler, which is needed to build
the "hybrid" fb_sdl component (hybrid means that it is both a regular
Linux program that is linked against the glibc and interacts with the
Linux world, as well a Genode component that interacts with the Genode
world). The sup++ library is normally part of the 'g++' package.

To avoid stumbling blocks like this, please revisit the prerequisites
listed here:
