I am trying to cross compile syslog-ng for my embedded platform. When I run ./configure pointing it to the proper tool chain, it indicates "checking for pthread_spin_lock... no". And when I compile, it complains - "iv_thr.h:97: error: conflicting type qualifiers for 'pthread_spinlock_t'"

I suspect ivykis (lib/ivykis/) is a bit buggy when cross-compiling. Since it fails to detect pthread_spin_lock, it will have HAVE_PTHREAD_SPIN_LOCK disabled, which in turn means that it will try to typedef pthread_spinlock_t to an int. But! Your embedded platform DOES have pthread_spin_lock_t, so this will fail.

I would suggest editing lib/ivykis/config.h after configure, and enabling HAVE_PTHREAD_SPIN_LOCK.

Hopefully this'll help.

(Why the detection fails, though, is not entirely clear to me..)

It'd make sense to forward this email to libivykis-discuss@lists.sourceforge.net so the ivykis authors become aware of the issue.

Upstream ivykis just assumes that pthread_spin_lock() is always there, i.e. it doesn't even do a configure test for it, so I think that this issue is due to a patch unique to syslog-ng's branch/fork of ivykis.

oops. my bad. probably messed up the configure test. sorry for bothering you Lennart.
