compile .so with .h












1















I have three files:



list.c, recursive.c, recursive.h


the 2nd and third are the header and .c of an auxiliary function called: recursive.



The first one is a file that im trying to compile as a .so. It does an include of recursive.h with:



#include "recursive.h"



Normally i would compile it with:



gcc -Wall -shared -fPIC -o list.so list.c


but whenever i run the code from a client program i get the following:



./shell: symbol lookup error: /home/list.so: undefined symbol: recursive





c gcc

    Where is the function recursive() defined?

  • @Ctx its defined in recursive.c. Prototyped in recursive.h

  • Then you will probably have to link recursive.c also into list.so

  • @Ctx I read some answers suggesting the same on the internet. But i dont know how to link a .c

            Dulmage-Mendelsohn matrix decomposition in Python

            Image
            0 Matlab has a function called dmperm that computes the so-called Dulmage–Mendelsohn decomposition of a n x n matrix. From wikipedia, the Dulmage–Mendelsohn is a partition of the vertices of a bipartite graph into subsets, with the property that two adjacent vertices belong to the same subset if and only if they are paired with each other in a perfect matching of the graph. Looking both on scipy and numpy, I could not find this function, nor some similar version. Is it possible to implement it using basic linear algebra operations? Any idea if this is implemented in some Python package? python matlab linear-algebra graph-theory matrix-decomposition share | improve this question
