Ok, I did:
1) Attempted reinstallation of all libraries. Machine reported that all 
libraries were the latest versions.
2) Using latest INSTALL file, cloned and installed Subsurface variant of 
libdivecomputer. No errors, warnings or messages.
    This important with respect to the compile error below.
3) Cloned and installed Subsurface variant of Marble.
4) Cloned Subsurface and invoked qmake-qt5
Upon make, the following error and warnings:

compiling qt-ui/downloadfromdivecomputer.cpp

make: *** [.obj/configuredivecomputerthreads.o] Error 1

HOWEVER:
1) When I build V4.3 on Fedora, no problem. Problem only with latest master.
2) When building latest master on Ubuntu, no problem.

I think you could believe I am quite exasperated!
Kind regards,
