Hello I am trying to create a shared object and use it in a program under cygwin with gcc. I seem to miss a point. If some kind soul could help me on that, I'd be very grateful.
Here's the code for the shared object (calc_mean.c): #include "calc_mean.h" double mean(double a, double b) { return (a+b) / 2; } Here's its header file (calc_mean.h): double mean(double, double); So, I compile that to a .so like so: $ gcc -shared -o libmean.so calc_mean.c Then, there's main.c that wants to use the shared object: #include <stdio.h> #include "calc_mean.h" int main(int argc, char* argv[]) { double v1, v2, m; v1 = 5.2; v2 = 7.9; m = mean(v1, v2); printf("The mean of %3.2f and %3.2f is %3.2f\n", v1, v2, m); return 0; } I try to compile main.c like so: $ gcc main.c -o main -L. -lmean However, the following error is returned: /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/../../../../i686-pc-cygwin/bin/ld: cannot find -lmean collect2: ld returned 1 exit status Obviously, I do something wrong here, but I have no idea what that could be.
