[libdispatch-dev] [PATCH] use libkqueue if sys/event.h is missing

[Joakim Johansson]

Unfortunately, it breaks on Solaris, as PKG_CHECK_MODULES isn't available:

-----
.
.
.
checking for sys/event.h... no
./configure: line 14665: syntax error near unexpected token `KQUEUE,'
./configure: line 14665: `  PKG_CHECK_MODULES(KQUEUE, libkqueue)'
-----

I'll see if I can figure it out...
