Re: [osg-users] Enabling notifications from within program?
Hi
You can set your own notify handler like this to check if you ever get messages
from osg:
class NH : public osg::NotifyHandler
{
public:
NH()
: m_out(osg_log.txt)
{
}
~NH()
{
m_out.close();
}
void notify (osg::NotifySeverity severity, const char *message)
{
m_out message;
}
private:
std::ofstream m_out;
};
osg::setNotifyHandler(new NH);
Cheers,
Sergey.

Hi Robert,
That's what I'm currently doing (ie using stack traces to try and
figure stuff out), but I was wondering why osg doesn't give me *any*
output at all. For instance, I'm apparently able to do a bunch of
stuff: Load an *.osg model, setup an animation path, create nodes,
etc, pretty much all of the scene setup goes fine up until I try to
create the viewer. Doesn't doing any of those things before the viewer
provide output when I've set the notify level to debug? I made sure I
compiled with OSG_DISABLE_NOTIFY (or whatever the exact wording for
that flag was) to allow notifications.

Hi Preet,
The osg::notify system isn't related to handling of std exceptions
except where some specific code might catch an exception and report
the output to osg::notify. This means that upping the notify level
won't effect how exceptions are handled.
The best thing to do is run a debugger and the look at the stack trace
where the application crashes.

Hiya,
I'm trying to debug a std::bad_alloc() exception from osg that doesn't
product any other output. I can't set environment variables, so I
tried:
osg::setNotifyLevel(osg::DEBUG_INFO);
This still doesn't give me any output. The system I'm on dumps stdout
and stderr to a log file in a specific directory and since Notify.cpp
dumps to both of those it seems like I should be seeing something, but
I'm not. However, I do get statements like std::cout Hello
std::endl outputted as expected when used in my application (just not
from osg). Am I missing something obvious?

Re: [osg-users] Enabling notifications from within program?
Thanks to all for the replies... I wasn't getting any output because
of some unrelated linking errors. After fixing them, debugging is
working as expected :)

I made sure I compiled with OSG_DISABLE_NOTIFY (or whatever the exact wording for that flag was) to allow notifications. Loading a file will certainly produce output with the proper OSG_LOG_LEVEL. I'm wondering if whatever subsystem is redirecting output to a log file in your application is maybe run after OSG sets up its logging and so they're going to different file descriptors?
