I need a simple timer thread in my application to pooling my OPC-UA server and my code crash when execute Browse Method (adapted by Lesson 6), with "Segmentation fault (core dumped)" error. Best Regards!

What version of Linux are you using? Can you provide a stack trace of the segfault'ing thread? Your best bet to get us to look at it would be to post a minimal sample (e.g. one file) that reproduces the bug. Cheers, Patrick

It doesn't contain a self contained example, and unfortunately I don't have the time to spend making it build. If you can provide a complete sample that reproduces the bug, I'd be happy to look at it, but it really needs to be either a single cpp file, or there must be a makefile or VS solution. I don't mind changing include and lib paths to pick-up the SDK, but anything more than that is really beyond the scope of the support I can offer. Cheers, Patrick Edited by user Thursday, June 18, 2015 9:16:28 AM(UTC) \| Reason: Typo
