in reply to Inline::C and gd

Beatnik,

This works for me (you can place the "include" within the code section). Your problem is quite odd since the c example works while the perl does not. If you do a "perl -V" do you see /usr/lib in the linker and libs section? Was your perl compiled with gcc? If it was another compiler/linker, that linker may not know about /usr/lib. 

#!/usr/local/bin/perl

use Inline C => DATA =>
           LIBS => '-lgd';
outtext();

__END__
__C__

#include "gd.h"

int outtext()
{ gdImagePtr im;
  FILE *out;
  im = gdImageCreate(100,100);
  out = fopen("foo.jpg", "wb");
  gdImageJpeg(im, out,-1);
  fclose(out);
  gdImageDestroy(im);
  return 1;
}

    a perl -V dump returns something like this :

      Okay. That's a different error message (undefined symbol jpeg_destroy). Doing an "nm -a libgd.so | grep jpeg_destroy" on my system shows that libgd.so has an unresolved dependency for that function. jpeg_destory is part of the jpg library. Do you have libjpg.so anywhere in your libpths?
