Hi, after the recent discussion here about Inline C, I decided to try one of the examples from the cookbook: how to access an so lib. But for some reason, I'm getting unresolved symbols, even though it builds properly. The example below is taken almost verbatim from the cookbook. 

#!/usr/bin/perl
print get('http://localhost');

use Inline C => Config =>
LIBS => '-lghttp',
INC => '-I/opt/gnome/include/';
use Inline C => <<'END_OF_C_CODE';

#include <ghttp.h> 

char *get(SV* uri) {
SV* buffer;
ghttp_request* request;

buffer = NEWSV(0,0);
request = ghttp_request_new();
ghttp_set_uri(request, SvPV(uri, PL_na));

ghttp_set_header(request, http_hdr_Connection, "close");

ghttp_prepare(request);
ghttp_process(request);

sv_catpv(buffer, ghttp_get_body(request));

ghttp_request_destroy(request);

return SvPV(buffer, PL_na);
}

#When I run it, it compiles fine, but I get this error when running: 
Had problems bootstrapping Inline module 'gethttp_bce4'

Can't load '_Inline/lib/auto/gethttp_bce4/gethttp_bce4.so' 
for module gethttp_bce4: _Inline/lib/auto/gethttp_bce4/gethttp_bce4.so: 
undefined symbol: http_hdr_Connection at /DynaLoader.pm line 229.

OK, so now I go to the gethttp_bce4.so and do an nm on it: 
Here is the relevant section of the output: 
nm gethttp_bce4.so -> 
 
00000d00 t frame_dummy 
000015b0 T get 
U ghttp_get_body 
U ghttp_prepare 
U ghttp_process 
U ghttp_request_destroy 
U ghttp_request_new 
U ghttp_set_header 
U ghttp_set_uri 
U http_hdr_Connection 
00002874 d p.0 
U pthread_getspecific 
 
Well all the subroutines needed are undefined. Why?? 
If I do an nm on libghttp.so.1, they are defined : 
nm libghttp.so.1 ->

So, what am I missing to cause those subroutines to get 
linked in?
