Yes, Marcus... I am certainly not an expert, and I've used C++ only
sporadically. Still, this must be the first time that I haven't solved
a compilation problem on my own (after 25+ years of linux).
I'm not a frequent IRC visitor, for the same reason.
I can't find any obvious mixup between versions. In each case I
carefully looked for old version laying around, checked */cmake
directories and */pkgconfig dirs for possible confusion.
The only issue I detected was about the fact that there were both
-gr38 (which is version 0.2.0) and real -0.2.0 versions to be found
on the 'net.
Please have a look at my reply to Vasil, and I'd really appreciate
pointers to where I went wrong.
