next: compilation error due to disabled zeromq

[andimik]

Problem

Although I have disabled zeromq (using ./configure --disable-output-uhd --disable-zeromq), I cannot compile the next branch. I fear there are some #if defined(HAVE_ZEROMQ) missing in Events.h and Events.cpp

As I am not a programmer I have no idea if I broke something when excluding everything in Events.cpp. See patch below.

another bug found and fixed

Furthermore, there was a missing #include <string.h> in Utils.cpp, otherwise I get the following error

make[1]: Verzeichnis „/home/andreas/apps/ODR-DabMod“ wird betreten

Compilation

But at least I could compile it near to the end, but not 100%

Hint:

After enabling zeromq (or changing to the master branch), everything works fine.
