stevieb's scratchpad

by stevieb (Monsignor)

The C program:

#include <stdio.h> #include <wiringPi.h> int main (){ char * ver = wiringPiVersion(); printf("wiringPi version: %s\n", ver); return 0; }

I compile like this:

gcc -o ver wpi_ver.c -lwiringPi

The addition to .h

extern char * wiringPiVersion(void);

The .c addition:

char * wiringPiVersion(void){ return "string"; # actually it's a `#define`, but I digress }

In my module's XS file, I have:

char * wiringPiVersion()

...and my Makefile.PL

LIBS => ['-lwiringPi'],

...and after re-installing the Perl module, I can access the function without any issue.
