    g++ undefined refernce

    hey guys..
    been a while since i've been here..but I need some help.
    This is driving me nuts, I'm getting an "undefined reference" error, but all the function prototypes and the code is there. Here's the command line I"m usingL


    g++ *.cpp -L/usr/local/ssl/lib -lcrypto -L/usr/lib -lnsl -ldl -lc -lm -c eti

    Here's the errors:


    # g++ *.cpp -L/usr/local/ssl/lib -lcrypto -L/usr/lib -o eti
    /tmp/ccvXWf45.o(.text+0x236): In function `MyProc(int, char**, pthread_mutex_t)':
    : undefined reference to `_STI_GetBalance(char*, long*, unsigned short)'
    /tmp/ccvXWf45.o(.text+0x27d): In function `MyProc(int, char**, pthread_mutex_t)':

    : undefined reference to `_STI_GetBalanceCode(char*, long*, unsigned short, unsigned long, char*, unsigned long)'
    collect2: ld returned 1 exit status

    Any ideas?

    If you could show us the function prototype/definition for the GetBalance function, we might be able to better help you. Since there is no compiler error, just a link error, it seems that there is a prototype -- the function is declared -- but no definition in the object files being linked -- either it's in another source or object file that you've forgotten to include, or there's a typeographic error in the actual function definition in the file so that the function in question does not match the expected name and argument type signature.

    Edit:
    I re-read the original post. I think it's most likely that some object file (or source file, for that matter) is not being included -- I suspect that all of the missing definitions are in some other source file.

    actually nvm, i took care of it. it was an issue with #defines, it wasn't properly parsing it
