将 libsndfile 源代码与 gcc 链接

Question

I just cloned libsndfile and created program.c file with the following contents:

#include <stdio.h>
#include <sndfile.h>
main() {
    printf("hello world");
}

My goal is to get this file to compile using gcc (if indeed sndfile.h is the right header to include), however, I am not competent with c code nor the gcc compiler.

So far I've been referencing the gcc docs and the libsndfile FAQ and haven't been able to come up with a solution. I'm not sure if I even have a 'library' yet to feed the gcc -l option . Do I need to go through some sort of build process with the libsndfile source code first or can I 'link' to .c files?

So far, with program.c and the libsndfile clone directory in the same directory, I've tried the following:

gcc 'pkg-config --cflags libsndfile' program.c -o hello
gcc 'pkg-config --cflags ./libsndfile/sndfile.pc.in' program.c -o hello

I'm coding on my raspberry pi model B and did not install libsndfile, so, nothing is on my path... maybe I should rename sndfile.pc.in to sndfile.pc and somehow put it on my path? (not a linux guru either!)

If there are some resources you think I should study please comment! I'm perfectly willing to accept answers that simply push me enough to figure things out. Any help would be much appreciated.

First make sure you have gcc installed:

sudo apt-get install gcc

Then, install libsndfile1-dev :

sudo apt-get install libsndfile1-dev

I slightly fixed you code to avoid some warnings:

#include <stdio.h>
#include <sndfile.h>

int main(void) {
  printf("hello world\n");
  return 0;
}

Now you can compile:

gcc -o hello program.c

Execution:

bebs@rasp:~$ ./hello                                     
hello world                                                                              
bebs@rasp:~$
