dynamic class loading doesn't find my functions!?
 

hiho@ll

i'm using dlopen and dlsym to load a class dynamically

everything works fine, but my main prog doesn't recognize the functions included by dlsym!!

compileerror:
/tmp/cchUTQgK.o(.text+0x185a): In function `main':
: undefined reference to `myserv::init(int, int, int, int, int, int, int, int)'
/tmp/cchUTQgK.o(.text+0x1977): In function `main':
: undefined reference to `myserv::start()'
collect2: ld returned 1 exit status


i understand why it doesn't find the functions (http://www.linuxjournal.com/article/3687), but although i'm using extern "C" directive
(in my server.cpp class (not the main app class) i have extern "C"{ function codings })

anyone knows what the problem could be?

maybe it's a compilerflag i don't know
or do i have to use extern "C" in the server.h too?

thx@ll

the compiler option -shared was missing :rolleyes:
