Re: Can run mono once and only once ( Mono locks up when calling pthread_getattr_np ).

by simozzer :: Rate this Message:

I've narrowed it down to a call in threads.c, line 766:

pthread_getattr_np(pthread_self(), &attr).

I'm still no wiser though. Does anyone have any insight as to why this call might be causing some kind of deadlock?

Thanks

Simozzer.

Can anyone please help me here?

I can run mono 1.2.6 absolutely fine with no problems but with 2.0 I always experience a lock-up. The lockup occurs both when I have built mono from trunk and also when i try installing the (unsupported) binary distribution.

Any hints to help me debug this would be much appreciated.

Cheers

Hello,

I wonder if anyone can help me with fixing this?

After lots of package upgrades I've finally managed to get mono 2.0 installed on my EEE PC -Yey!

It seems, however, I can run any mono application once then I have to reboot - Boo!

After reboot the first mono application i try to run runs fine - the next freezes :(

I've tried debugging using gdb but i've never gdb debugged anything in my life so I haven't got very far. Here follows the gdb output from two successive runs of HelloWorld.exe:

Starting program: /opt/mono/2.0/bin/mono /home/user/HelloWorld.exe

At this point gdb freezes - what keys can i press to halt execution and inspect the call stack to find out what the heck is happening?

Can anyone help? P.lease, it would be wonderful to get Mono and MonoDevelop up and running on a 4GB handheld 'toy' :o)

Cheers
