<pre>I've tried to compile libmnl without the HAVE_VISIBILITY_HIDDEN option, so in
my case config.h defines
#undef HAVE_VISIBILITY_HIDDEN
internal.h uses this option and declares the EXPORT_SYMBOL macro:
#include "config.h"
#ifdef HAVE_VISIBILITY_HIDDEN
# define __visible __attribute__((visibility("default")))
# define EXPORT_SYMBOL(x) typeof(x) (x) __visible
#else
# define EXPORT_SYMBOL
#endif
This causes compilation problems when EXPORT_SYMBOL is used, e.g. in socket.c:
EXPORT_SYMBOL(mnl_socket_get_fd);
int mnl_socket_get_fd(const struct mnl_socket *nl)
{
return nl->fd;
}
So I think EXPORT_SYMBOL should be defined as
...
#else
# define EXPORT_SYMBOL(x)
#endif
?</pre>
