[so] [ tema 2 ] Legare biblioteca partajata la aplicatie

[Dragos Tarcatu]

Modifica headerul crypto.h la modul urmator:

/*
 *  crypto.h
 *  
[...]
 *
 */


#ifdef __cplusplus
extern "C" {
#endif

int crypt_base64(void *in, int len, void *out);

[...]

#ifdef __cplusplus
}
#endif

Are de a face cu procesul de name mangling din C++.

Am probleme la compilare folosind biblioteca partajata.
Includ header-ul crypto.h si creez obiectul main.o .Cand incerc sa creez 
executabilul primesc 
main.cpp:(.text+0x47): undefined reference to `crypt_des(void*, int, void*)'

Comanda folosita este
g++  -Wl,-rpath -llibcrypto -L. main.o -o bin 

In alte situatii (la folosirea altor biblioteci *.so - nu la tema) nu am avut 
probleme. Sa incarc biblioteca la runtime nu am incercat [1].
