Undefined reference to to `blacs_gridinfo_'

Question

I am getting a undefined reference errors while building LSDMap (Locally Scaled Diffusion Map). What libraries contain the missing references?

Answer 1

They are from BLACS. Notice blacs_gridinfo_ and a simple google search identifies the other ones (like google.com/search?q=pdlarnv&oq=pdlarnv) as also from BLACS or ARPACK.

Etime() is a non-standard intrinsic in some compilers (https://gcc.gnu.org/onlinedocs/gfortran/ETIME.html) but your compiler doesn't know it. You will have to find some substitute for it.

Generally, I recommend you to search using your favourite search engine for the missing name without the underscores and it should not be difficult to find the corresponding library.
