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

            For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease.
