Ok, but you shouldn't have had to do that, there seems to be something
wrong with your system: pkg-config should already be looking in
/usr/lib/x86_64-linux-gnu/pkgconfig , you should not have had to specify
it.

Do not type the \ as they are, they are there only to indicate that the
line is to be continued.

Also, did the summary at the end of ./configure notify that the gcc
plugin infrastructure was built?  This is required for getting the gcc
pluging way of using StarPU working.

All that being said, the example you use (block.c) does *not* use the
gcc plugin for C extension, so you can just skip the related part, i.e.

-fplugin=`pkg-config starpu-1.1 --variable=gccplugin`

and thus only keep the cflags and the libs parts.
