[Xenomai-help] pthread_cond_init() returns ENOMEM

[Xenomai-help] pthread_cond_init() returns ENOMEM

[Mike McTernan]

Hi,

I'm trying to port a large complex app to Xenomai using the POSIX skin,
and so far so good!

But I've found pthread_cond_init() it reporting ENOMEM to a userspace
app.  Looking back up the sources I think this maybe because
xnheap_alloc() is exhausted in the kernel.

I'm using the Xenomai VMware image from
http://www.cs.ru.nl/lab/xenomai/, it's version 2.4.3.  Do I need to
update, or is there a way I can increase the heap?  

I can't see how to do it from the docs, please point me in the right
direction.

Kind Regards,

Mike

You should update it at some point, since we fixed significant bugs since then.
But you don't need this to increase the heap.

Check XENO_OPT_SYS_HEAPSZ in the Xenomai nucleus menu (Kconfig).
