Hi all,
just trying to compile a trivial c++ program which uses alpm. In the linking phase i get those errors:

I'm just missing something on alpm linking? I've added only -lalpm to my compiler line
I believe you should use alpm_list_t , not __alpm_list_t . All other errors seem to be fixed in 3.1 . I don't know why, but many many functions in pacman 3.0 were not public, and this has only been fixed in 3.1 .
