  12. Hi.  Does anybody know if there are any special tricks to using shared
  13. libraries with gcc/g++ (version 2.3.3)?
  14.  
  15. I'm using a sparc platform and successfully build shared libraries using
  16. Sun C++ 2.1 by compiling with -PIC and putting all global variables into one
  17. object which becomes libxx.sa.0.1 and the other objects into libxx.so.0.1.
  18.  
  19. ...but when it comes to g++, the libraries build OK with -fPIC but when I am
  20. linkingan application, I get a failure with unresolved symbols which are all
  21. defined in libxx.sa.0.1.
  22.  
  23. gcc/g++ is using sun's linker.
  24.  
  25. Any help would be appreciated.
  26.  
  27. Regards,
