Compilation fails if OpenMP is disabled
In src/graph/graph_openmp.cc, around line 47 (amongst others), 1277a9d4:
#!cpp
40 size_t openmp_get_num_threads()
41 {
42 #ifdef USING_OPENMP
43 return omp_get_max_threads();
44 #else
45 throw GraphException("OpenMP was not enabled during compilation")
46 #endif
47 }
Line 45 is missing a ";" at the line end.
