[zeromq-dev] C++ programming help (Was not: Various Majordomo protocol versions)

[Brett Viren]

Hi Simon,

This apparently has nothing to do with majordomo protocol versions.

It would help if you show your code but based on the small hints, I
agree with Brian.  Remove the "*" in front of "sock".

If the build failed to find cppzmq header files you'd see much different
errors.
