Thread: Undefined reference

Hey guys, first I'd like to thank you for all your help in the past. Anyway, when I compile I get a whole bunch of "undefined reference to" and then a function call. I have these functions defined, and the appropriate files included. For example
error:
"main.o(.text+0x235):/home/bbare/converting/c/main.cpp:68: undefined reference to `Convert_and_Score(int, double, int, double, double&)'"

in main I have #include "In_out.h"
In_out.h:

Code:

void Convert_and_Score(int chrom_num1, double cM_percent1, int chrom_num2, double cM_percent2, double &outscore);

oh ya
the call in main that the error is referencing:

Code:

    double score;
    double fChromNumOne = PGAGetRealAllele(ctx, p, pop, 1);
    double fChromNumTwo = PGAGetRealAllele(ctx, p, pop, 3);
    int iChromNumOne = (int)(fChromNumOne * NUM_CHROM);
    int iChromNumTwo = (int)(fChromNumTwo * NUM_CHROM);

    double loc1 = PGAGetRealAllele(ctx, p, pop, 2);
    double loc2 = PGAGetRealAllele(ctx, p, pop, 4);

    score = 0;
    Convert_and_Score(iChromNumOne, loc1, iChromNumTwo, loc2, score);

and those PGA functions are also undefined references yet I have the file that they are defined in included...

Sorry, yes, the declarations are in the header. The defintions are in the file of the same name just .cpp extension.
Makefile:

Code:

In_out.o: In_out.h In_out.cpp
        g++ $(FLAGS) -c In_out.cpp

...

ga_ee: math_utils.o calc_subs.o EM.o EE_utils.o In_out.o main.o
        g++ math_utils.o calc_subs.o EM.o EE_utils.o main.o -o ga_ee

yay! stupid mistakes are so much better. easier to fix!
