Summary and Info:
I get undefined references when using alpm_option_set_ignoregrps and alpm_option_set_ignorepkgs. I discovered this after trying to import a libalpm Python extension (created using SWIG).

>>> import alpm
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "alpm.py", line 7, in <module>
import _alpm
ImportError: /home/darwin/Projects/arch/pyalpm/pkg/usr/lib/python2.5/site-packages/_alpm.so: undefined symbol: alpm_option_set_ignorepkgs

When I set SWIG to ignore those two functions, _alpm.so loads fine.

I also created a dummy program that calls the two functions and I get this upon compilation:

darwin@excelsior:/tmp$ gcc test.c -lalpm
/tmp/cc85uUDg.o: In function `main':
test.c:(.text+0x18): undefined reference to `alpm_option_set_ignoregrps'
test.c:(.text+0x23): undefined reference to `alpm_option_set_ignorepkgs'
collect2: ld returned 1 exit status

BTW, I only need to link to libalpm right? Or am I missing something here?

Steps to Reproduce:

/* test.c */
#include <alpm.h>

int main()
{
alpm_list_t *a;
alpm_option_set_ignoregrps(a);
alpm_option_set_ignorepkgs(a);
return 0;
}

$ gcc test.c -lalpm
