Hi, See the following output given below by `git submodule status`: $ git submodule status +c7b9787f0b7826a87f07ce00cbfe4947b8521101 external/devxlib (heads/master) d0197c76ae76bbf4d3fed20444fac31af550069d external/eigensolver_gpu (v0.3.1-7-gd0197c7) +6fef49bcfc4a380432f15734ed0ca1f0b0388977 external/fox (4.1.2-89-g6fef49b) +4b3c7c249f6a2cfed76603d9987cf5164fa6f9e1 external/lapack (v3.7.0-1026-g4b3c7c249) +2899044d2a6828aa16e0189913662bc35ce8f645 external/mbd (0.12.1-43-g2899044) +2b9973c12e85397fa9564370f6cced16f8428834 external/wannier90 (v3.1.0-35-g2b9973c) What's the meaning of the '+' sign at the beginning? Why do some submodules have this symbol, but some submodules don't? Regards -- Assoc.
