Now when I change my code to
#include <stdio.h>
#include <stdlib.h>
#include "glpk.h"


int main(void)
{
    LPX *lp;
    char *model;
    model = "transp.mod";
    char *output;
    output = "transp.out";
    lp = lpx_read_model(model, NULL, output);
}

And I put the code under /include
it reports
transp.c:(.text+0x40): undefined reference to `glp_lpx_read_model'
collect2: ld returned 1 exit status

If I compile sample.c under /include
it reports the similar problems.
/tmp/ccOj7oOg.o: In function `main':

Does anybody have ideas about this kind of problem. Thanks
