Robert,
Attached is a copy of the PThread.cpp file from OSG 3.3.7 that I modified that
allows Linux systems to take full advantage of the pthread scheduling
parameters. The changes I made are all within the
#ifdef ALLOW_PRIORITY_SCHEDULING
define and the static int
Hi,
I would like to revisit this topic again as I see that even in the current
trunk(3.3.8) as of this date May 04, 2015, the linux platform is still crippled
inside of Openthreads/PThread API, from running priority/real-time scheduling
policies.
I will like to open a discussion about

Robert,
When I mentioned crippled, I did not mean that as a bad or derogatory
comment. Maybe saying something like intentionally disabled would have
been a better choice of words, my apologies if my wording offended anyone in
any way.
Basic threading is working fine under Linux. If the user
Hi Curtis,
There has to be a historical reason for need for the #ifndef __linux__
around the thread scheduling assignment. As I'm not the author of
this block of code I can only check the code and svn log's. I'm
currently working on a complex bug fix on another area of the OSG so
can't dive
Robert,
There is already a define around all the priority scheduling
calls to protect people from accidentally using them:
#ifdef ALLOW_PRIORITY_SCHEDULING
Which seems to have to be defined in the calling program as I cannot find this
any place inside of OSG other than the pthreads source.

I spent few hours on this and I have things to report. First, there are

Hi Robert,
My first problem was that I had selected the option to build
OpenThreads with QT in cmake for some reason. So I rebuilt with this option
off..
My apologies on that issue...
At least it is now using the pthreads section properly.
However, as Nick stated in his post, the openthreads

Nick,
__linux__ is defined someplace in the gcc compiler
as it finds the current arch and os, etc., installed.
you can:
cpp -dM /dev/null
and see all the gcc defines output.
I see that __linux is still there as well, at least for
the time being.
ALLOW_PRIORITY_SCHEDULING, however seems to

I have 64bit Kubuntu 14.04 installed here and when I follow Curtis's
suggestion I get:
$ cpp -dM /dev/null | grep __linux
#define __linux 1
Ubuntu 13.04 raring got it from the store installed on the laptop I
bought in a rush :-)

Checked out the latest trunk version myself and I am still having the same
issues here with the OpenThread calls and the example code I sent to Nick. We
are running OpenSuse 12.3 64-bit here.
The calls all return good status. In fact the getSchedulePolicy and the

svn/trunk to see if it things work now as you were expecting?

Yep, that is correct.

Hi Robert,
I just build the latest from the trunk - revision 14188, and no changes.
Still geting failures (-1) on these calls. But on Windows it works well.
Any ideas? Could you give it a shot to the attached file, it is
selfcontained
Thanks a bunch!
